+flow, which uses [`DefaultAzureCredential`](https://learn.microsoft.com/en-us/python/api/azure-identity/azure.identity.defaultazurecredential)
+to automatically discover and use available credentials in the following order:
+
+1. **Environment Variables** — `AZURE_CLIENT_ID`, `AZURE_CLIENT_SECRET`, and `AZURE_TENANT_ID` for Service Principal authentication
+2. **Managed Identity** — Uses the managed identity assigned to the pod
+3. **Azure CLI** — Uses credentials from the Azure CLI if available
+4. **Azure PowerShell** — Uses credentials from Azure PowerShell if available
+
+This approach is particularly useful for getting started with development and testing; it allows
+the SDK to attempt multiple authentication mechanisms seamlessly across different environments.
+However, this is not recommended for production. Please refer to the
+[official Azure guidance](https://learn.microsoft.com/en-us/dotnet/azure/sdk/authentication/credential-chains?tabs=dac#usage-guidance-for-defaultazurecredential)

+# Compression
+
+<!-- SPDX-License-Identifier: CC-BY-4.0 -->
+
+By default, backups and WAL files are archived **uncompressed**. However, the
+Barman Cloud Plugin supports multiple compression algorithms via
+`barman-cloud-backup` and `barman-cloud-wal-archive`, allowing you to optimize
+for space, speed, or a balance of both.
+
+### Supported Compression Algorithms
+
+- `bzip2`
+- `gzip`
+- `lz4` (WAL only)
+- `snappy`
+- `xz` (WAL only)
+- `zstd` (WAL only)
+
+Compression settings for base backups and WAL archives are configured
+independently. For implementation details, refer to the corresponding API
+definitions:
+
+- [`DataBackupConfiguration`](https://pkg.go.dev/github.com/cloudnative-pg/barman-cloud/pkg/api#DataBackupConfiguration)
+- [`WALBackupConfiguration`](https://pkg.go.dev/github.com/cloudnative-pg/barman-cloud/pkg/api#WalBackupConfiguration)
+
+:::important
+Compression impacts both performance and storage efficiency. Choose the right
+algorithm based on your recovery time objectives (RTO), storage capacity, and
+network throughput.

+:::important
+Before proceeding, make sure to review the following sections of the
+CloudNativePG documentation:
+
+- [**Backup**](https://cloudnative-pg.io/documentation/current/backup/)
+- [**WAL Archiving**](https://cloudnative-pg.io/documentation/current/wal_archiving/)
+- [**Recovery**](https://cloudnative-pg.io/documentation/current/recovery/)
+:::
+
+The **Barman Cloud Plugin** enables **hot (online) backups** of PostgreSQL
+clusters in CloudNativePG through [`barman-cloud`](https://pgbarman.org),
+supporting continuous physical backups and WAL archiving to an **object
+store**—without interrupting write operations.
+
+It also supports both **full recovery** and **Point-in-Time Recovery (PITR)**
+of a PostgreSQL cluster.
+
+## The Object Store
+
+At the core is the [`ObjectStore` custom resource (CRD)](plugin-barman-cloud.v1.md#objectstorespec),
+which acts as the interface between the PostgreSQL cluster and the target
+object storage system. It allows you to configure:
+
+- **Authentication and bucket location** via the `.spec.configuration` section
+- **WAL archiving** settings—such as compression type, parallelism, and
+  server-side encryption—under `.spec.configuration.wal`
+- **Base backup options**—with similar settings for compression, concurrency,
+  and encryption—under `.spec.configuration.data`
+- **Retention policies** to manage the life-cycle of archived WALs and backups
+  via `.spec.configuration.retentionPolicy`
+
+WAL files are archived in the `wals` directory, while base backups are stored
+as **tarballs** in the `base` directory, following the
+[Barman Cloud convention](https://docs.pgbarman.org/cloud/latest/usage/#object-store-layout).
+
+The plugin also offers advanced capabilities, including
+[backup tagging](misc.md#backup-object-tagging) and
+[extra options for backups and WAL archiving](misc.md#extra-options-for-backup-and-wal-archiving).
+
+:::tip
+For details, refer to the
+[API reference for the `ObjectStore` resource](plugin-barman-cloud.v1.md#objectstorespec).
+:::
+
+## Integration with a CloudNativePG Cluster
+
+CloudNativePG can delegate continuous backup and recovery responsibilities to
+the **Barman Cloud Plugin** by configuring the `.spec.plugins` section of a
+`Cluster` resource. This setup requires a corresponding `ObjectStore` resource
+to be defined.
+
+:::important
+While it is technically possible to reuse the same `ObjectStore` for multiple
+`Cluster` resources within the same namespace, it is strongly recommended to
+dedicate one object store per PostgreSQL cluster to ensure data isolation and
+operational clarity.
+:::
+
+The following example demonstrates how to configure a CloudNativePG cluster
+named `cluster-example` to use a previously defined `ObjectStore` (also named
+`cluster-example`) in the same namespace. Setting `isWALArchiver: true` enables
+WAL archiving through the plugin:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+metadata:
+  name: cluster-example
+spec:
+  # Other cluster settings...
+  plugins:
+    - name: barman-cloud.cloudnative-pg.io
+      isWALArchiver: true
+      parameters:
+        barmanObjectName: cluster-example
+```
+
+## Backup of a Postgres Cluster
+
+Once the object store is defined and the `Cluster` is configured to use the
+Barman Cloud Plugin, **WAL archiving is activated immediately** on the
+PostgreSQL primary.
+
+Physical base backups are seamlessly managed by CloudNativePG using the
+`Backup` and `ScheduledBackup` resources, respectively for
+[on-demand](https://cloudnative-pg.io/documentation/current/backup/#on-demand-backups)
+and
+[scheduled](https://cloudnative-pg.io/documentation/current/backup/#scheduled-backups)
+backups.
+
+To use the Barman Cloud Plugin, you must set the `method` to `plugin` and
+configure the `pluginConfiguration` section as shown:
+
+```yaml
+[...]
+spec:
+  method: plugin
+  pluginConfiguration:
+    name: barman-cloud.cloudnative-pg.io
+  [...]
+```
+
+With this configuration, CloudNativePG supports:
+
+- Backups from both **primary** and **standby** instances
+- Backups from **designated primaries** in a distributed topology using
+  [replica clusters](https://cloudnative-pg.io/documentation/current/replica_cluster/)
+
+:::tip
+For details on how to back up from a standby, refer to the official documentation:
+[Backup from a standby](https://cloudnative-pg.io/documentation/current/backup/#backup-from-a-standby).
+:::
+
+:::important
+Both backup and WAL archiving operations are executed by sidecar containers
+running in the same pod as the PostgreSQL `Cluster` primary instance—except
+when backups are taken from a standby, in which case the sidecar runs alongside
+the standby pod.
+The sidecar containers use a [dedicated container image](images.md) that
+includes only the supported version of Barman Cloud.
+:::
+
+## Recovery of a Postgres Cluster
+
+In PostgreSQL, *recovery* refers to the process of starting a database instance
+from an existing backup.  The Barman Cloud Plugin integrates with CloudNativePG
+to support both **full recovery** and **Point-in-Time Recovery (PITR)** from an
+object store.
+
+Recovery in this context is *not in-place*: it bootstraps a brand-new
+PostgreSQL cluster from a backup and replays the necessary WAL files to reach
+the desired recovery target.
+
+To perform a recovery, define an *external cluster* that references the
+appropriate `ObjectStore`, and use it as the source in the `bootstrap` section
+of the target cluster:
+
+```yaml
+[...]
+spec:
+  [...]
+  bootstrap:
+    recovery:
+      source: source
+  externalClusters:
+  - name: source
+    plugin:
+      name: barman-cloud.cloudnative-pg.io
+      parameters:
+        barmanObjectName: cluster-example
+        serverName: cluster-example
+  [...]
+```
+
+The critical element here is the `externalClusters` section of the `Cluster`
+resource, where the `plugin` stanza instructs CloudNativePG to use the Barman
+Cloud Plugin to access the object store for recovery.
+
+This same mechanism can be used for a variety of scenarios enabled by the
+CloudNativePG API, including:
+
+* **Full cluster recovery** from the latest backup
+* **Point-in-Time Recovery (PITR)**
+* Bootstrapping **replica clusters** in a distributed topology
+
+:::tip
+For complete instructions and advanced use cases, refer to the official
+[Recovery documentation](https://cloudnative-pg.io/documentation/current/recovery/).

+
+:::important
+1. The plugin **must** be installed in the same namespace as the CloudNativePG
+   operator (typically `cnpg-system`).
+
+2. Keep in mind that the operator's **listening namespaces** may differ from its
+   installation namespace. Double-check this to avoid configuration issues.
+:::
+
+## Verifying the Requirements
+
+Before installing the plugin, make sure the [requirements](intro.md#requirements) are met.
+
+### CloudNativePG Version
+
+Ensure you're running a version of CloudNativePG that is compatible with the
+plugin. If installed in the default `cnpg-system` namespace, you can verify the
+version with:
+
+```sh
+kubectl get deployment -n cnpg-system cnpg-controller-manager \
+  -o jsonpath="{.spec.template.spec.containers[*].image}"
+```
+
+Example output:
+
+```output
+ghcr.io/cloudnative-pg/cloudnative-pg:1.26.0
+```
+
+The version **must be 1.26 or newer**.
+
+### cert-manager
+
+Use the [cmctl](https://cert-manager.io/docs/reference/cmctl/#installation)
+tool to confirm that `cert-manager` is installed and available:
+
+```sh
+cmctl check api
+```
+
+Example output:
+
+```output
+The cert-manager API is ready
+```
+
+Both checks are required before proceeding with the installation.
+
+## Installing the Barman Cloud Plugin
+
+import { InstallationSnippet } from '@site/src/components/Installation';
+
+Install the plugin using `kubectl` by applying the manifest for the latest
+release:
+
+<InstallationSnippet />
+
+Example output:
+
+```output

+<!-- SPDX-License-Identifier: CC-BY-4.0 -->
+
+The **Barman Cloud Plugin** for [CloudNativePG](https://cloudnative-pg.io/)
+enables online continuous physical backups of PostgreSQL clusters to object storage
+using the `barman-cloud` suite from the [Barman](https://docs.pgbarman.org/release/latest/)
+project.
+
+:::important
+If you plan to migrate your existing CloudNativePG cluster to the new
+plugin-based approach using the Barman Cloud Plugin, see
+["Migrating from Built-in CloudNativePG Backup"](migration.md)
+for detailed instructions.
+:::
+
+## Requirements
+
+Before using the Barman Cloud Plugin, ensure that the following components are
+installed and properly configured:
+
+- [CloudNativePG](https://cloudnative-pg.io) version 1.26 or later
+
+  - We strongly recommend version 1.27.0 or later, which includes improved
+    error handling and status reporting for the plugin.
+  - If you are running an earlier release, refer to the
+    [upgrade guide](https://cloudnative-pg.io/documentation/current/installation_upgrade).
+
+- [cert-manager](https://cert-manager.io/)
+
+  - The recommended way to enable secure TLS communication between the plugin
+    and the operator.
+  - Alternatively, you can provide your own certificate bundles. See the
+    [CloudNativePG documentation on TLS configuration](https://cloudnative-pg.io/documentation/current/cnpg_i/#configuring-tls-certificates).
+
+- [`kubectl-cnpg`](https://cloudnative-pg.io/documentation/current/kubectl-plugin/)
+  plugin (optional but recommended)
+
+  - Simplifies debugging and monitoring with additional status and inspection
+    commands.
+  - Multiple installation options are available in the
+    [installation guide](https://cloudnative-pg.io/documentation/current/kubectl-plugin/#install).
+
+## Key Features
+
+This plugin provides the following capabilities:
+
+- Physical online backup of the data directory
+- Physical restore of the data directory
+- Write-Ahead Log (WAL) archiving
+- WAL restore
+- Full cluster recovery
+- Point-in-Time Recovery (PITR)
+- Seamless integration with replica clusters for bootstrap and WAL restore from archive
+
+:::important
+The Barman Cloud Plugin is designed to **replace the in-tree object storage support**
+previously provided via the `.spec.backup.barmanObjectStore` section in the
+`Cluster` resource.
+Backups created using the in-tree approach are fully supported and compatible
+with this plugin.
+:::
+
+## Supported Object Storage Providers
+
+The plugin works with all storage backends supported by `barman-cloud`, including:
+
+- **Amazon S3**
+- **Google Cloud Storage**
+- **Microsoft Azure Blob Storage**
+
+In addition, the following S3-compatible and simulator solutions have been
+tested and verified:
+
+- [MinIO](https://min.io/) – An S3-compatible storage solution
+- [Azurite](https://github.com/Azure/Azurite) – A simulator for Azure Blob Storage
+- [fake-gcs-server](https://github.com/fsouza/fake-gcs-server) – A simulator for Google Cloud Storage

+# Migrating from Built-in CloudNativePG Backup
+
+<!-- SPDX-License-Identifier: CC-BY-4.0 -->
+
+The in-tree support for Barman Cloud in CloudNativePG is **deprecated starting
+from version 1.26** and will be removed in a future release.
+
+If you're currently relying on the built-in Barman Cloud integration, you can
+migrate seamlessly to the new **plugin-based architecture** using the Barman
+Cloud Plugin, without data loss. Follow these steps:
+
+- [Install the Barman Cloud Plugin](installation.mdx)
+- Create an `ObjectStore` resource by translating the contents of the
+  `.spec.backup.barmanObjectStore` section from your existing `Cluster`
+  definition
+- Modify the `Cluster` resource in a single atomic change to switch from
+  in-tree backup to the plugin
+- Update any `ScheduledBackup` resources to use the plugin
+- Update the `externalClusters` configuration, where applicable
+
+:::tip
+For a working example, refer to [this commit](https://github.com/cloudnative-pg/cnpg-playground/commit/596f30e252896edf8f734991c3538df87630f6f7)
+from the [CloudNativePG Playground project](https://github.com/cloudnative-pg/cnpg-playground),
+which demonstrates a full migration.
+:::
+
+---
+
+## Step 1: Define the `ObjectStore`
+
+Begin by creating an `ObjectStore` resource in the same namespace as your
+PostgreSQL `Cluster`.
+
+There is a **direct mapping** between the `.spec.backup.barmanObjectStore`
+section in CloudNativePG and the `.spec.configuration` field in the
+`ObjectStore` CR. The conversion is mostly mechanical, with one key difference:
+
+:::warning
+In the plugin architecture, retention policies are defined as part of the `ObjectStore`.
+In contrast, the in-tree implementation defined them at the `Cluster` level.
+:::
+
+If your `Cluster` used `.spec.backup.retentionPolicy`, move that configuration
+to `.spec.retentionPolicy` in the `ObjectStore`.
+
+---
+
+### Example
+
+Here’s an excerpt from a traditional in-tree CloudNativePG backup configuration
+taken from the CloudNativePG Playground project:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+metadata:
+  name: pg-eu
+spec:
+  # [...]
+  backup:
+    barmanObjectStore:
+      destinationPath: s3://backups/
+      endpointURL: http://minio-eu:9000
+      s3Credentials:
+        accessKeyId:
+          name: minio-eu
+          key: ACCESS_KEY_ID
+        secretAccessKey:
+          name: minio-eu
+          key: ACCESS_SECRET_KEY
+      wal:
+        compression: gzip
+```
+
+This configuration translates to the following `ObjectStore` resource for the
+plugin:
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: minio-eu
+spec:
+  configuration:
+    destinationPath: s3://backups/
+    endpointURL: http://minio-eu:9000
+    s3Credentials:
+      accessKeyId:
+        name: minio-eu
+        key: ACCESS_KEY_ID
+      secretAccessKey:
+        name: minio-eu
+        key: ACCESS_SECRET_KEY
+    wal:
+      compression: gzip
+```
+
+As you can see, the contents of `barmanObjectStore` have been copied directly
+under the `configuration` field of the `ObjectStore` resource, using the same
+secret references.
+
+## Step 2: Update the `Cluster` for plugin WAL archiving
+
+Once the `ObjectStore` resource is in place, update the `Cluster` resource as
+follows in a single atomic change:
+
+- Remove the `.spec.backup.barmanObjectStore` section
+- Remove `.spec.backup.retentionPolicy` if it was defined (as it is now in the
+  `ObjectStore`)
+- Remove the entire `spec.backup` section if it is now empty
+- Add `barman-cloud.cloudnative-pg.io` to the `plugins` list, as described in
+  [Configuring WAL archiving](usage.md#configuring-wal-archiving)
+
+This will trigger a rolling update of the `Cluster`, switching continuous
+backup from the in-tree implementation to the plugin-based approach.
+
+### Example
+
+The updated `pg-eu` cluster will have this configuration instead of the
+previous `backup` section:
+
+```yaml
+  plugins:
+  - name: barman-cloud.cloudnative-pg.io
+    isWALArchiver: true
+    parameters:
+      barmanObjectName: minio-eu
+```
+
+---
+
+## Step 3: Update the `ScheduledBackup`
+
+After switching the `Cluster` to use the plugin, update your `ScheduledBackup`
+resources to match.
+
+Set the backup `method` to `plugin` and reference the plugin name via
+`pluginConfiguration`, as shown in ["Performing a base backup"](usage.md#performing-a-base-backup).
+
+### Example
+
+Original in-tree `ScheduledBackup`:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: ScheduledBackup
+metadata:
+  name: pg-eu-backup
+spec:
+  cluster:
+    name: pg-eu
+  schedule: '0 0 0 * * *'
+  backupOwnerReference: self
+```
+
+Updated version using the plugin:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: ScheduledBackup
+metadata:
+  name: pg-eu-backup
+spec:
+  cluster:
+    name: pg-eu
+  schedule: '0 0 0 * * *'
+  backupOwnerReference: self
+  method: plugin
+  pluginConfiguration:
+    name: barman-cloud.cloudnative-pg.io
+```
+
+---
+
+## Step 4: Update the `externalClusters` configuration
+
+If your `Cluster` relies on one or more external clusters that use the in-tree
+Barman Cloud integration, you need to update those configurations to use the
+plugin-based architecture.
+
+When a replica cluster fetches WAL files or base backups from an external
+source that used the built-in backup method, follow these steps:
+
+1. Create a corresponding `ObjectStore` resource for the external cluster, as
+   shown in [Step 1](#step-1-define-the-objectstore)
+2. Update the `externalClusters` section of your replica cluster to use the
+   plugin instead of the in-tree `barmanObjectStore` field
+
+### Example
+
+Consider the original configuration using in-tree Barman Cloud:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+metadata:
+  name: pg-us
+spec:
+  # [...]
+  externalClusters:
+  - name: pg-eu
+    barmanObjectStore:
+      destinationPath: s3://backups/
+      endpointURL: http://minio-eu:9000
+      serverName: pg-eu
+      s3Credentials:
+        accessKeyId:
+          name: minio-eu
+          key: ACCESS_KEY_ID
+        secretAccessKey:
+          name: minio-eu
+          key: ACCESS_SECRET_KEY
+      wal:
+        compression: gzip
+```
+
+Create the `ObjectStore` resource for the external cluster:
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: minio-eu
+spec:
+  configuration:
+    destinationPath: s3://backups/
+    endpointURL: http://minio-eu:9000
+    s3Credentials:
+    accessKeyId:
+        name: minio-eu
+        key: ACCESS_KEY_ID
+    secretAccessKey:
+        name: minio-eu
+        key: ACCESS_SECRET_KEY
+    wal:
+      compression: gzip
+```
+
+Update the external cluster configuration to use the plugin:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+metadata:
+  name: pg-us
+spec:
+  # [...]
+  externalClusters:
+  - name: pg-eu
+    plugin:
+      name: barman-cloud.cloudnative-pg.io
+      parameters:
+        barmanObjectName: minio-eu
+        serverName: pg-eu
+```
+
+## Step 5: Verify your metrics
+
+When migrating from the in-core solution to the plugin-based approach, you need
+to monitor a different set of metrics, as described in the
+["Observability"](observability.md) section.
+
+The table below summarizes the name changes between the old in-core metrics and
+the new plugin-based ones:
+
+| Old metric name                                  | New metric name                                                  |
+| ------------------------------------------------ | ---------------------------------------------------------------- |
+| `cnpg_collector_last_failed_backup_timestamp`    | `barman_cloud_cloudnative_pg_io_last_failed_backup_timestamp`    |
+| `cnpg_collector_last_available_backup_timestamp` | `barman_cloud_cloudnative_pg_io_last_available_backup_timestamp` |
+| `cnpg_collector_first_recoverability_point`      | `barman_cloud_cloudnative_pg_io_first_recoverability_point`      |

+
+## Backup Object Tagging
+
+You can attach key-value metadata tags to backup artifacts—such as base
+backups, WAL files, and history files—via the `.spec.configuration` section of
+the `ObjectStore` resource.
+
+- `tags`: applied to base backups and WAL files
+- `historyTags`: applied to history files only
+
+### Example
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: my-store
+spec:
+  configuration:
+    [...]
+    tags:
+      backupRetentionPolicy: "expire"
+    historyTags:
+      backupRetentionPolicy: "keep"
+  [...]
+```
+
+## Extra Options for Backup and WAL Archiving
+
+You can pass additional command-line arguments to `barman-cloud-backup` and
+`barman-cloud-wal-archive` using the `additionalCommandArgs` field in the
+`ObjectStore` configuration.
+
+- `.spec.configuration.data.additionalCommandArgs`: for `barman-cloud-backup`
+- `.spec.configuration.wal.archiveAdditionalCommandArgs`: for `barman-cloud-wal-archive`
+
+Each field accepts a list of string arguments. If an argument is already
+configured elsewhere in the plugin, the duplicate will be ignored.
+
+### Example: Extra Backup Options
+
+```yaml
+kind: ObjectStore
+metadata:
+  name: my-store
+spec:
+  configuration:
+    data:
+      additionalCommandArgs:
+        - "--min-chunk-size=5MB"
+        - "--read-timeout=60"
+```
+
+### Example: Extra WAL Archive Options
+
+```yaml
+kind: ObjectStore
+metadata:
+  name: my-store
+spec:
+  configuration:
+    wal:
+      archiveAdditionalCommandArgs:
+        - "--max-concurrency=1"
+        - "--read-timeout=60"
+```
+
+For a complete list of supported options, refer to the
+[official Barman Cloud documentation](https://docs.pgbarman.org/release/latest/).
+
+## Enable the pprof debug server for the sidecar
+
+You can enable the instance sidecar's pprof debug HTTP server by adding the `--pprof-server=<address>` flag to the container's
+arguments via `.spec.instanceSidecarConfiguration.additionalContainerArgs`.
+
+Pass a bind address in the form `<host>:<port>` (for example, `0.0.0.0:6061`).
+An empty value disables the server (disabled by default).
+
+### Example
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: my-store
+spec:
+  instanceSidecarConfiguration:
+    additionalContainerArgs:
+      - "--pprof-server=0.0.0.0:6061"

+# Object Store Providers
+
+<!-- SPDX-License-Identifier: CC-BY-4.0 -->
+
+The Barman Cloud Plugin enables the storage of PostgreSQL cluster backup files
+in any object storage service supported by the
+[Barman Cloud infrastructure](https://docs.pgbarman.org/release/latest/).
+
+Currently, Barman Cloud supports the following providers:
+
+- [Amazon S3](#aws-s3)
+- [Microsoft Azure Blob Storage](#azure-blob-storage)
+- [Google Cloud Storage](#google-cloud-storage)
+
+You may also use any S3- or Azure-compatible implementation of the above
+services.
+
+To configure object storage with Barman Cloud, you must define an
+[`ObjectStore` object](plugin-barman-cloud.v1.md#objectstore), which
+establishes the connection between your PostgreSQL cluster and the object
+storage backend.
+
+Configuration details — particularly around authentication — will vary depending on
+the specific object storage provider you are using.
+
+The following sections detail the setup for each.
+
+---
+
+## AWS S3
+
+[AWS Simple Storage Service (S3)](https://aws.amazon.com/s3/) is one of the
+most widely adopted object storage solutions.
+
+The Barman Cloud plugin for CloudNativePG integrates with S3 through two
+primary authentication mechanisms:
+
+- [IAM Roles for Service Accounts (IRSA)](https://docs.aws.amazon.com/eks/latest/userguide/iam-roles-for-service-accounts.html) —
+  recommended for clusters running on EKS
+- Access keys — using `ACCESS_KEY_ID` and `ACCESS_SECRET_KEY` credentials
+
+### Access Keys
+
+To authenticate using access keys, you’ll need:
+
+- `ACCESS_KEY_ID`: the public key used to authenticate to S3
+- `ACCESS_SECRET_KEY`: the corresponding secret key
+- `ACCESS_SESSION_TOKEN`: (optional) a temporary session token, if required
+
+These credentials must be stored securely in a Kubernetes secret:
+
+```sh
+kubectl create secret generic aws-creds \
+  --from-literal=ACCESS_KEY_ID=<access key here> \
+  --from-literal=ACCESS_SECRET_KEY=<secret key here>
+# --from-literal=ACCESS_SESSION_TOKEN=<session token here> # if required
+```
+
+The credentials will be encrypted at rest if your Kubernetes environment
+supports it.
+
+You can then reference the secret in your `ObjectStore` definition:
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: aws-store
+spec:
+  configuration:
+    destinationPath: "s3://BUCKET_NAME/path/to/folder"
+    s3Credentials:
+      accessKeyId:
+        name: aws-creds
+        key: ACCESS_KEY_ID
+      secretAccessKey:
+        name: aws-creds
+        key: ACCESS_SECRET_KEY
+  [...]
+```
+
+### IAM Role for Service Account (IRSA)
+
+To use IRSA with EKS, configure the service account of the PostgreSQL cluster
+with the appropriate annotation:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+metadata:
+  [...]
+spec:
+  serviceAccountTemplate:
+    metadata:
+      annotations:
+        eks.amazonaws.com/role-arn: arn:[...]
+        [...]
+```
+
+### S3 Lifecycle Policy
+
+Barman Cloud uploads backup files to S3 but does not modify or delete them afterward.
+To enhance data durability and protect against accidental or malicious loss,
+it's recommended to implement the following best practices:
+
+- Enable object versioning
+- Enable object locking to prevent objects from being deleted or overwritten
+  for a defined period or indefinitely (this provides an additional layer of
+  protection against accidental deletion and ransomware attacks)
+- Set lifecycle rules to expire current versions a few days after your Barman
+  retention window
+- Expire non-current versions after a longer period
+
+These strategies help you safeguard backups without requiring broad delete
+permissions, ensuring both security and compliance with minimal operational
+overhead.
+
+
+### S3-Compatible Storage Providers
+
+You can use S3-compatible services like **MinIO**, **Linode (Akamai) Object Storage**,
+or **DigitalOcean Spaces** by specifying a custom `endpointURL`.
+
+Example with Linode (Akamai) Object Storage (`us-east1`):
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: linode-store
+spec:
+  configuration:
+    destinationPath: "s3://BUCKET_NAME/"
+    endpointURL: "https://us-east1.linodeobjects.com"
+    s3Credentials:
+    [...]
+  [...]
+```
+
+Recent changes to the [boto3 implementation](https://github.com/boto/boto3/issues/4392)
+of [Amazon S3 Data Integrity Protections](https://docs.aws.amazon.com/sdkref/latest/guide/feature-dataintegrity.html)
+may lead to the `x-amz-content-sha256` error when using the Barman Cloud
+Plugin.
+
+If you encounter this issue (see [GitHub issue #393](https://github.com/cloudnative-pg/plugin-barman-cloud/issues/393)),
+you can apply the following workaround by setting specific environment
+variables in the `ObjectStore` resource:
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: linode-store
+spec:
+  instanceSidecarConfiguration:
+    env:
+      - name: AWS_REQUEST_CHECKSUM_CALCULATION
+        value: when_required
+      - name: AWS_RESPONSE_CHECKSUM_VALIDATION
+        value: when_required
+  [...]
+```
+
+These settings ensure that checksum calculations and validations are only
+applied when explicitly required, avoiding compatibility issues with certain
+S3-compatible storage providers.
+
+Example with DigitalOcean Spaces (SFO3, path-style):
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: digitalocean-store
+spec:
+  configuration:
+    destinationPath: "s3://BUCKET_NAME/path/to/folder"
+    endpointURL: "https://sfo3.digitaloceanspaces.com"
+    s3Credentials:
+    [...]
+  [...]
+```
+
+### Using Object Storage with a Private CA
+
+For object storage services (e.g., MinIO) that use HTTPS with certificates
+signed by a private CA, set the `endpointCA` field in the `ObjectStore`
+definition. Unless you already have it, create a Kubernetes `Secret` with the
+CA bundle:
+
+```sh
+kubectl create secret generic my-ca-secret --from-file=ca.crt
+```
+
+Then reference it:
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: minio-store
+spec:
+  configuration:
+    endpointURL: <myEndpointURL>
+    endpointCA:
+      name: my-ca-secret
+      key: ca.crt
+  [...]
+```
+
+<!-- TODO: does this also apply to the plugin? -->
+:::note
+If you want `ConfigMaps` and `Secrets` to be **automatically** reloaded by
+instances, you can add a label with the key `cnpg.io/reload` to the
+`Secrets`/`ConfigMaps`. Otherwise, you will have to reload the instances using the
+`kubectl cnpg reload` subcommand.
+:::
+
+---
+
+## Azure Blob Storage
+
+[Azure Blob Storage](https://azure.microsoft.com/en-us/services/storage/blobs/)
+is Microsoft’s cloud-based object storage solution.
+
+Barman Cloud supports the following authentication methods:
+
+- [Connection String](https://learn.microsoft.com/en-us/azure/storage/common/storage-configure-connection-string)
+- Storage Account Name + [Access Key](https://learn.microsoft.com/en-us/azure/storage/common/storage-account-keys-manage)
+- Storage Account Name + [SAS Token](https://learn.microsoft.com/en-us/azure/storage/blobs/sas-service-create)
+- [Azure AD Workload Identity](https://azure.github.io/azure-workload-identity/docs/introduction.html)
+
+### Azure AD Workload Identity
+
+This method avoids storing credentials in Kubernetes via the
+`.spec.configuration.inheritFromAzureAD` option:
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: azure-store
+spec:
+  configuration:
+    destinationPath: "<destination path here>"
+    azureCredentials:
+      inheritFromAzureAD: true
+  [...]
+```
+
+### Access Key, SAS Token, or Connection String
+
+Store credentials in a Kubernetes secret:
+
+```sh
+kubectl create secret generic azure-creds \
+  --from-literal=AZURE_STORAGE_ACCOUNT=<storage account name> \
+  --from-literal=AZURE_STORAGE_KEY=<storage account key> \
+  --from-literal=AZURE_STORAGE_SAS_TOKEN=<SAS token> \
+  --from-literal=AZURE_STORAGE_CONNECTION_STRING=<connection string>
+```
+
+Then reference the required keys in your `ObjectStore`:
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: azure-store
+spec:
+  configuration:
+    destinationPath: "<destination path here>"
+    azureCredentials:
+      connectionString:
+        name: azure-creds
+        key: AZURE_CONNECTION_STRING
+      storageAccount:
+        name: azure-creds
+        key: AZURE_STORAGE_ACCOUNT
+      storageKey:
+        name: azure-creds
+        key: AZURE_STORAGE_KEY
+      storageSasToken:
+        name: azure-creds
+        key: AZURE_STORAGE_SAS_TOKEN
+  [...]
+```
+
+For Azure Blob, the destination path format is:
+
+```
+<http|https>://<account-name>.<service-name>.core.windows.net/<container>/<blob>
+```
+
+### Azure-Compatible Providers
+
+If you're using a different implementation (e.g., Azurite or emulator):
+
+```
+<http|https>://<local-machine-address>:<port>/<account-name>/<container>/<blob>
+```
+
+---
+
+## Google Cloud Storage
+
+[Google Cloud Storage](https://cloud.google.com/storage/) is supported with two
+authentication modes:
+
+- **GKE Workload Identity** (recommended inside Google Kubernetes Engine)
+- **Service Account JSON key** via the `GOOGLE_APPLICATION_CREDENTIALS` environment variable
+
+### GKE Workload Identity
+
+Use the [Workload Identity authentication](https://cloud.google.com/kubernetes-engine/docs/how-to/workload-identity)
+when running in GKE:
+
+1. Set `googleCredentials.gkeEnvironment` to `true` in the `ObjectStore`
+   resource
+2. Annotate the `serviceAccountTemplate` in the `Cluster` resource with the GCP
+   service account
+
+For example, in the `ObjectStore` resource:
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: google-store
+spec:
+  configuration:
+    destinationPath: "gs://<bucket>/<folder>"
+    googleCredentials:
+      gkeEnvironment: true
+```
+
+And in the `Cluster` resource:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+spec:
+  serviceAccountTemplate:
+    metadata:
+      annotations:
+        iam.gke.io/gcp-service-account: [...].iam.gserviceaccount.com
+```
+
+### Service Account JSON Key
+
+Follow Google’s [authentication setup](https://cloud.google.com/docs/authentication/getting-started),
+then:
+
+```sh
+kubectl create secret generic backup-creds --from-file=gcsCredentials=gcs_credentials_file.json
+```
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: google-store
+spec:
+  configuration:
+    destinationPath: "gs://<bucket>/<folder>"
+    googleCredentials:
+      applicationCredentials:
+        name: backup-creds
+        key: gcsCredentials
+  [...]
+```
+
+:::important
+This authentication method generates a JSON file within the container
+with all the credentials required to access your Google Cloud Storage
+bucket. As a result, if someone gains access to the `Pod`, they will also have
+write permissions to the bucket.
+:::
+
+---
+
+
+## MinIO Object Store
+
+In order to use the Tenant resource you first need to deploy the
+[MinIO operator](https://docs.min.io/community/minio-object-store/operations/deployments/installation.html).
+For the latest documentation of MinIO, please refer to the
+[MinIO official documentation](https://docs.min.io/community/minio-object-store/).
+
+MinIO Object Store's API is compatible with S3, and the default configuration of the Tenant
+will create these services:
+- `<tenant>-console` on port 9090 (with autocert) or 9443 (without autocert)
+- `<tenant>-hl` on port 9000
+Where `<tenant>` is the `metadata.name` you assigned to your Tenant resource.
+
+:::note
+The `<tenant>-console` service will only be available if you have enabled the
+[MinIO Console](https://docs.min.io/community/minio-object-store/administration/minio-console.html).
+
+For example, the following Tenant:
+```yml
+apiVersion: minio.min.io/v2
+kind: Tenant
+metadata:
+  name: cnpg-backups
+spec:
+  [...]
+```
+would have services called `cnpg-backups-console` and `cnpg-backups-hl` respectively.
+
+The `console` service is for managing the tenant, while the `hl` service exposes the S3
+compatible API. If your tenant is configured with `requestAutoCert` you will communicate
+to these services over HTTPS, if not you will use HTTP.
+
+For authentication you can use your username and password, or create an access key.
+Whichever method you choose, it has to be stored as a secret.
+
+```sh
+kubectl create secret generic minio-creds \
+  --from-literal=MINIO_ACCESS_KEY=<minio access key or username> \
+  --from-literal=MINIO_SECRET_KEY=<minio secret key or password>
+```
+
+Finally, create the Barman ObjectStore:
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: minio-store
+spec:
+  configuration:
+    destinationPath: s3://BUCKET_NAME/
+    endpointURL: http://<tenant>-hl:9000
+    s3Credentials:
+      accessKeyId:
+        name: minio-creds
+        key: MINIO_ACCESS_KEY
+      secretAccessKey:
+        name: minio-creds
+        key: MINIO_SECRET_KEY
+  [...]
+```
+
+:::important
+Verify on `s3://BUCKET_NAME/` the presence of archived WAL files before
+proceeding with a backup.

+# Resource name migration guide
+
+<!-- SPDX-License-Identifier: CC-BY-4.0 -->
+
+:::warning
+Before proceeding with the migration process, please:
+1. **Read this guide in its entirety** to understand what changes will be made
+2. **Test in a non-production environment** first if possible
+3. **Ensure you have proper backups** of your cluster configuration
+
+This migration will delete old RBAC resources only after the
+`plugin-barman-cloud` upgrade. While the operation is designed to be safe, you
+should review and understand the changes before proceeding. The maintainers of
+this project are not responsible for any issues that may arise during
+migration.
+
+**Note:** This guide assumes you are using the default `cnpg-system` namespace.
+:::
+
+## Overview
+
+Starting from version **0.8.0**, the `plugin-barman-cloud` deployment manifests
+use more specific, prefixed resource names to avoid conflicts with other
+components deployed in the same Kubernetes cluster.
+
+## What Changed
+
+The following resources have been renamed to use proper prefixes.
+
+### Cluster-scoped Resources
+
+| Old Name                   | New Name                                 |
+|----------------------------|------------------------------------------|
+| `metrics-auth-role`        | `barman-plugin-metrics-auth-role`        |
+| `metrics-auth-rolebinding` | `barman-plugin-metrics-auth-rolebinding` |
+| `metrics-reader`           | `barman-plugin-metrics-reader`           |
+| `objectstore-viewer-role`  | `barman-plugin-objectstore-viewer-role`  |
+| `objectstore-editor-role`  | `barman-plugin-objectstore-editor-role`  |
+
+### Namespace-scoped Resources
+
+| Old Name                      | New Name                                    | Namespace     |
+|-------------------------------|---------------------------------------------|---------------|
+| `leader-election-role`        | `barman-plugin-leader-election-role`        | `cnpg-system` |
+| `leader-election-rolebinding` | `barman-plugin-leader-election-rolebinding` | `cnpg-system` |
+
+## Why This Change?
+
+Using generic names for cluster-wide resources is discouraged as they may
+conflict with other components deployed in the same cluster. The new names make
+it clear that these resources belong to the Barman Cloud plugin and help avoid
+naming collisions.
+
+## Migration Instructions
+
+This three steps migration process is straightforward and can be completed with
+a few `kubectl` commands.
+
+### Step 1: Upgrade plugin-barman-cloud
+
+Please refer to the [Installation](installation.mdx) section to deploy the new
+`plugin-barman-cloud` release.
+
+### Step 2: Delete Old Cluster-scoped Resources
+
+:::danger Verify Resources Before Deletion
+**IMPORTANT**: The old resource names are generic and could potentially belong
+to other components in your cluster.
+
+**Before deleting each resource, verify it belongs to the Barman Cloud plugin
+by checking:**
+- For `objectstore-*` roles: Look for `barmancloud.cnpg.io` in the API groups
+- For `metrics-*` roles: Check if they reference the `plugin-barman-cloud`
+  ServiceAccount in `cnpg-system` namespace
+- For other roles: Look for labels like `app.kubernetes.io/name: plugin-barman-cloud`
+
+If a resource doesn't have these indicators, **DO NOT DELETE IT** as it may
+belong to another application.
+
+Carefully review the output of each verification command before proceeding with
+the `delete`.
+:::
+
+:::tip Dry Run First
+You can add `--dry-run=client` to any `kubectl delete` command to preview what
+would be deleted without actually removing anything.
+:::
+
+**Only proceed if you've verified these resources belong to the Barman Cloud
+plugin (see warning above).**
+
+For each resource below, first verify it belongs to Barman Cloud, then delete
+it:
+
+```bash
+# 1. Check metrics-auth-rolebinding FIRST (we'll check the role after)
+# Look for references to plugin-barman-cloud ServiceAccount
+kubectl describe clusterrolebinding metrics-auth-rolebinding
+# If it references plugin-barman-cloud ServiceAccount in cnpg-system namespace,
+# delete it:
+kubectl delete clusterrolebinding metrics-auth-rolebinding
+
+# 2. Check metrics-auth-role
+# Look for references to authentication.k8s.io and authorization.k8s.io
+kubectl describe clusterrole metrics-auth-role
+# Verify it's not being used by any other rolebindings:
+kubectl get clusterrolebinding -o json \
+  | jq -r '.items[] | select(.roleRef.name=="metrics-auth-role") \
+  | .metadata.name'
+# If the above returns nothing (role is not in use) and the role looks like the
+# Barman Cloud one, delete it (see warnings section):
+kubectl delete clusterrole metrics-auth-role
+
+# 3. Check objectstore-viewer-role
+# Look for barmancloud.cnpg.io API group or
+# for `app.kubernetes.io/name: plugin-barman-cloud` label
+kubectl describe clusterrole objectstore-viewer-role
+# If it shows barmancloud.cnpg.io in API groups, delete it:
+kubectl delete clusterrole objectstore-viewer-role
+
+# 4. Check objectstore-editor-role
+# Look for barmancloud.cnpg.io API group or
+# for `app.kubernetes.io/name: plugin-barman-cloud` label
+kubectl describe clusterrole objectstore-editor-role
+# If it shows barmancloud.cnpg.io in API groups, delete it:
+kubectl delete clusterrole objectstore-editor-role
+
+# 5. Check metrics-reader (MOST DANGEROUS - very generic name)
+# First, check if it's being used by any rolebindings OTHER than barman's:
+kubectl get clusterrolebinding -o json | jq -r '.items[] \
+  | select(.roleRef.name=="metrics-reader") \
+  | "\(.metadata.name) -> \(.subjects[0].name) in \(.subjects[0].namespace)"'
+# If this shows ANY rolebindings, review them carefully. Only proceed if
+# they're all Barman-related.  Then check the role itself:
+kubectl describe clusterrole metrics-reader
+# If it ONLY has nonResourceURLs: /metrics and NO other rolebindings use it,
+# delete it:
+kubectl delete clusterrole metrics-reader
+```
+
+:::warning
+The `metrics-reader` role is particularly dangerous to delete blindly. Many
+monitoring systems use this exact name. Only delete it if:
+
+1. You've verified it ONLY grants access to `/metrics`
+2. No other rolebindings reference it (checked with the jq command above)
+3. You're certain it was created by the Barman Cloud plugin
+
+If you're unsure, it's safer to leave it and let the new
+`barman-plugin-metrics-reader` role coexist with it.
+:::
+
+If any resource is not found during the `describe` command, that's okay - it
+means it was never created or already deleted. Simply skip the delete command
+for that resource.
+
+### Step 3: Delete Old Namespace-scoped Resources
+
+Delete the old namespace-scoped resources in the `cnpg-system` namespace:
+
+```bash
+# Delete the old leader-election resources
+kubectl delete role leader-election-role -n cnpg-system
+kubectl delete rolebinding leader-election-rolebinding -n cnpg-system
+```
+
+If any resource is not found, that's okay - it means it was never created or
+already deleted.
+
+## Impact
+
+- **Permissions:** If you have custom RBAC rules or tools that reference the
+  old resource names, they will need to be updated.
+- **External Users:** If end users have been granted the
+  `objectstore-viewer-role` or `objectstore-editor-role`, they will need to be
+  re-granted the new role names (`barman-plugin-objectstore-viewer-role` and
+  `barman-plugin-objectstore-editor-role`).
+
+## Verification
+
+After migration, verify that the new resources are created:
+
+```bash
+# Check cluster-scoped resources
+kubectl get clusterrole | grep barman
+kubectl get clusterrolebinding | grep barman
+
+# Check namespace-scoped resources
+kubectl get role,rolebinding -n cnpg-system | grep barman
+```
+
+You should see the new prefixed resource names.
+
+## Troubleshooting
+
+### Plugin Not Starting After Migration
+
+If the plugin fails to start after migration, check:
+
+1. **ServiceAccount permissions:** Ensure the `plugin-barman-cloud` ServiceAccount is bound to the new roles:
+   ```bash
+   kubectl get clusterrolebinding barman-plugin-metrics-auth-rolebinding -o yaml
+   kubectl get rolebinding barman-plugin-leader-election-rolebinding -n cnpg-system -o yaml
+   ```
+
+2. **Role references:** Verify that the rolebindings reference the correct role names:
+   ```bash
+   kubectl describe rolebinding barman-plugin-leader-election-rolebinding -n cnpg-system
+   kubectl describe clusterrolebinding barman-plugin-metrics-auth-rolebinding
+   ```
+
+## Support
+
+If you encounter issues during migration, please open an issue on the [GitHub
+repository](https://github.com/cloudnative-pg/plugin-barman-cloud/issues).

+# Retention Policies
+
+<!-- SPDX-License-Identifier: CC-BY-4.0 -->
+
+The Barman Cloud Plugin supports **automated cleanup of obsolete backups** via
+retention policies, configured in the `.spec.retentionPolicy` field of the
+`ObjectStore` resource.
+
+:::note
+This feature uses the `barman-cloud-backup-delete` command with the
+`--retention-policy "RECOVERY WINDOW OF {{ value }} {{ unit }}"` syntax.
+:::
+
+#### Example: 30-Day Retention Policy
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: my-store
+spec:
+  [...]
+  retentionPolicy: "30d"
+````
+
+:::note
+A **recovery window retention policy** ensures the cluster can be restored to
+any point in time between the calculated *Point of Recoverability* (PoR) and
+the latest WAL archive. The PoR is defined as `current time - recovery window`.
+The **first valid backup** is the most recent backup completed before the PoR.
+Backups older than that are marked as *obsolete* and deleted after the next
+backup completes.

+# Troubleshooting
+
+<!-- SPDX-License-Identifier: CC-BY-4.0 -->
+
+This guide helps you diagnose and resolve common issues with the Barman Cloud
+plugin.
+
+:::important
+We are continuously improving the integration between CloudNativePG and the
+Barman Cloud plugin as it moves toward greater stability and maturity. For this
+reason, we recommend using the latest available version of both components.
+See the [*Requirements* section](intro.md#requirements) for details.
+:::
+
+:::note
+The following commands assume you installed the CloudNativePG operator in
+the default `cnpg-system` namespace. If you installed it in a different
+namespace, adjust the commands accordingly.
+:::
+
+## Viewing Logs
+
+To troubleshoot effectively, you’ll often need to review logs from multiple
+sources:
+
+```sh
+# View operator logs (includes plugin interaction logs)
+kubectl logs -n cnpg-system deployment/cnpg-controller-manager -f
+
+# View plugin manager logs
+kubectl logs -n cnpg-system deployment/barman-cloud -f
+
+# View sidecar container logs (Barman Cloud operations)
+kubectl logs -n <namespace> <cluster-pod-name> -c plugin-barman-cloud -f
+
+# View all containers in a pod
+kubectl logs -n <namespace> <cluster-pod-name> --all-containers=true
+
+# View previous container logs (if container restarted)
+kubectl logs -n <namespace> <cluster-pod-name> -c plugin-barman-cloud --previous
+```
+
+## Common Issues
+
+### Plugin Installation Issues
+
+#### Plugin pods not starting
+
+**Symptoms:**
+
+- Plugin pods stuck in `CrashLoopBackOff` or `Error`
+- Plugin deployment not ready
+
+**Possible causes and solutions:**
+
+1. **Certificate issues**
+
+   ```sh
+   # Check if cert-manager is installed and running
+   kubectl get pods -n cert-manager
+
+   # Check if the plugin certificate is created
+   kubectl get certificates -n cnpg-system
+   ```
+
+   If cert-manager is not installed, install it first:
+
+   ```sh
+   # Note: other installation methods for cert-manager are available
+   kubectl apply -f \
+     https://github.com/cert-manager/cert-manager/releases/latest/download/cert-manager.yaml
+   ```
+
+   If you are using your own certificates without cert-manager, you will need
+   to verify the entire certificate chain yourself.
+
+
+2. **Image pull errors**
+
+   ```sh
+   # Check pod events for image pull errors
+   kubectl describe pod -n cnpg-system -l app=barman-cloud
+   ```
+
+   Verify the image exists and you have proper credentials if using a private
+   registry.
+
+
+3. **Resource constraints**
+
+   ```sh
+   # Check node resources
+   kubectl top nodes
+   kubectl describe nodes
+   ```
+
+   Make sure your cluster has sufficient CPU and memory resources.
+
+### Backup Failures
+
+#### Quick Backup Troubleshooting Checklist
+
+When a backup fails, follow these steps in order:
+
+1. **Check backup status**:
+
+   ```sh
+   kubectl get backups.postgresql.cnpg.io -n <namespace>
+   ```
+2. **Get error details and target pod**:
+
+   ```sh
+   kubectl describe backups.postgresql.cnpg.io \
+     -n <namespace> <backup-name>
+
+   kubectl get backups.postgresql.cnpg.io \
+     -n <namespace> <backup-name> \
+     -o jsonpath='{.status.instanceID.podName}'
+   ```
+3. **Check the target pod’s sidecar logs**:
+
+   ```sh
+   TARGET_POD=$(kubectl get backups.postgresql.cnpg.io \
+     -n <namespace> <backup-name> \
+     -o jsonpath='{.status.instanceID.podName}')
+
+   kubectl logs \
+     -n <namespace> $TARGET_POD -c plugin-barman-cloud \
+     --tail=100 | grep -E "ERROR|FATAL|panic"
+   ```
+4. **Check cluster events**:
+
+   ```sh
+   kubectl get events -n <namespace> \
+     --field-selector involvedObject.name=<cluster-name> \
+     --sort-by='.lastTimestamp'
+   ```
+5. **Verify plugin is running**:
+
+   ```sh
+   kubectl get pods \
+     -n cnpg-system -l app=barman-cloud
+   ```
+6. **Check operator logs**:
+
+   ```sh
+   kubectl logs \
+     -n cnpg-system deployment/cnpg-controller-manager \
+     --tail=100 | grep -i "backup\|plugin"
+   ```
+7. **Check plugin manager logs**:
+
+   ```sh
+   kubectl logs \
+     -n cnpg-system deployment/barman-cloud --tail=100
+   ```
+
+#### Backup job fails immediately
+
+**Symptoms:**
+
+- Backup pods terminate with error
+- No backup files appear in object storage
+- Backup shows `failed` phase with various error messages
+
+**Common failure modes and solutions:**
+
+1. **"requested plugin is not available" errors**
+
+   ```
+   requested plugin is not available: barman
+   requested plugin is not available: barman-cloud
+   requested plugin is not available: barman-cloud.cloudnative-pg.io
+   ```
+   
+   **Cause:** The plugin name in the Cluster configuration doesn’t match the
+   deployed plugin, or the plugin isn’t registered.
+   
+   **Solution:** 
+   
+   a. **Check plugin registration:**
+
+   ```sh
+   # If you have the `cnpg` plugin installed (v1.27.0+)
+   kubectl cnpg status -n <namespace> <cluster-name>
+   ```
+   
+   Look for the "Plugins status" section:
+   ```
+   Plugins status
+   Name                            Version  Status  Reported Operator Capabilities
+   ----                            -------  ------  ------------------------------
+   barman-cloud.cloudnative-pg.io  0.6.0    N/A     Reconciler Hooks, Lifecycle Service
+   ```
+   
+   b. **Verify plugin name in `Cluster` spec**:
+
+   ```yaml
+   apiVersion: postgresql.cnpg.io/v1
+   kind: Cluster
+   spec:
+     plugins:
+       - name: barman-cloud.cloudnative-pg.io
+         parameters:
+           barmanObjectStore: <your-objectstore-name>
+   ```
+   
+   c. **Check plugin deployment is running**:
+
+   ```sh
+   kubectl get deployment -n cnpg-system barman-cloud
+   ```
+
+2. **"rpc error: code = Unknown desc = panic caught: assignment to entry in nil map" errors**
+   
+   **Cause:** Misconfiguration in the `ObjectStore` (e.g., typo or missing field).
+   
+   **Solution:** 
+
+   - Review sidecar logs for details
+   - Verify `ObjectStore` configuration and secrets
+   - Common issues include:
+     - Missing or incorrect secret references
+     - Typos in configuration parameters
+     - Missing required environment variables in secrets
+
+#### Backup performance issues
+
+**Symptoms:**
+
+- Backups take extremely long
+- Backups timeout
+
+**Plugin-specific considerations:**
+
+1. **Check `ObjectStore` parallelism settings**
+   - Adjust `maxParallel` in `ObjectStore` configuration
+   - Monitor sidecar container resource usage during backups
+
+2. **Verify plugin resource allocation**
+   - Check if the sidecar container has sufficient CPU/memory
+   - Review plugin container logs for resource-related warnings
+
+:::tip
+For Barman-specific features like compression, encryption, and performance
+tuning, refer to the [Barman documentation](https://docs.pgbarman.org/latest/).
+:::
+
+### WAL Archiving Issues
+
+#### WAL archiving stops
+
+**Symptoms:**
+
+- WAL files accumulate on the primary
+- Cluster shows WAL archiving warnings
+- Sidecar logs show WAL errors
+
+**Debugging steps:**
+
+1. **Check plugin sidecar logs for WAL archiving errors**
+   ```sh
+   # Check recent WAL archive operations in sidecar
+   kubectl logs -n <namespace> <primary-pod> -c plugin-barman-cloud \
+     --tail=50 | grep -i wal
+   ```
+
+2. **Check ObjectStore configuration for WAL settings**
+   - Ensure ObjectStore has proper WAL retention settings
+   - Verify credentials have permissions for WAL operations
+
+### Restore Issues
+
+#### Restore fails during recovery
+
+**Symptoms:**
+
+- New cluster stuck in recovery
+- Plugin sidecar shows restore errors
+- PostgreSQL won’t start
+
+**Debugging steps:**
+
+1. **Check plugin sidecar logs during restore**
+
+   ```sh
+   # Check the sidecar logs on the recovering cluster pods
+   kubectl logs -n <namespace> <cluster-pod-name> \
+     -c plugin-barman-cloud --tail=100
+   
+   # Look for restore-related errors
+   kubectl logs -n <namespace> <cluster-pod-name> \
+     -c plugin-barman-cloud | grep -E "restore|recovery|ERROR"
+   ```
+
+2. **Verify plugin can access backups**
+
+   ```sh
+   # Check if `ObjectStore` is properly configured for restore
+   kubectl get objectstores.barmancloud.cnpg.io \
+     -n <namespace> <objectstore-name> -o yaml
+   
+   # Check PostgreSQL recovery logs
+   kubectl logs -n <namespace> <cluster-pod> \
+     -c postgres | grep -i recovery
+   ```
+
+:::tip
+For detailed Barman restore operations and troubleshooting, refer to the
+[Barman documentation](https://docs.pgbarman.org/latest/barman-cloud-restore.html).
+:::
+
+#### Point-in-time recovery (PITR) configuration issues
+
+**Symptoms:**
+
+- PITR doesn’t reach target time
+- WAL access errors
+- Recovery halts early
+
+**Debugging steps:**
+
+1. **Verify PITR configuration in the `Cluster` spec**
+
+   ```yaml
+   apiVersion: postgresql.cnpg.io/v1
+   kind: Cluster
+   metadata:
+     name: <cluster-restore-name>
+   spec:
+     storage:
+       size: 1Gi
+
+     bootstrap:
+       recovery:

+### Plugin Configuration Issues
+
+#### Plugin cannot connect to object storage
+
+**Symptoms:**
+
+- Sidecar logs show connection errors
+- Backups fail with authentication or network errors
+- `ObjectStore` resource reports errors
+
+**Solution:**
+
+1. **Verify `ObjectStore` CRD configuration and secrets**
+
+   ```sh
+   # Check ObjectStore resource status
+   kubectl get objectstores.barmancloud.cnpg.io \
+     -n <namespace> <objectstore-name> -o yaml
+   
+   # Verify the secret exists and has correct keys for your provider
+   kubectl get secret -n <namespace> <secret-name> \
+     -o jsonpath='{.data}' | jq 'keys'
+   ```
+
+2. **Check sidecar logs for connectivity issues**
+   ```sh
+   kubectl logs -n <namespace> <cluster-pod> \
+     -c plugin-barman-cloud | grep -E "connect|timeout|SSL|cert"
+   ```
+
+3. **Adjust provider-specific settings (endpoint, path style, etc.)**
+   - See [Object Store Configuration](object_stores.md) for provider-specific settings
+   - Ensure `endpointURL` and `s3UsePathStyle` match your storage type
+   - Verify network policies allow egress to your storage provider
+
+## Diagnostic Commands
+
+### Using the `cnpg` plugin for `kubectl`
+
+The `cnpg` plugin for `kubectl` provides extended debugging capabilities.
+Keep it updated:
+
+```sh
+# Install or update the `cnpg` plugin
+kubectl krew install cnpg
+# Or using an alternative method: https://cloudnative-pg.io/documentation/current/kubectl-plugin/#install
+
+# Check plugin status (requires CNPG 1.27.0+)
+kubectl cnpg status <cluster-name> -n <namespace>
+
+# View cluster status in detail
+kubectl cnpg status <cluster-name> -n <namespace> --verbose
+```
+
+## Getting Help
+
+If problems persist:
+
+1. **Check the documentation**
+
+   - [Installation Guide](installation.mdx)
+   - [Object Store Configuration](object_stores.md) (for provider-specific settings)
+   - [Usage Examples](usage.md)
+
+
+2. **Gather diagnostic information**
+
+   ```sh
+   # Create a diagnostic bundle (⚠️ sanitize these before sharing!)
+   kubectl get objectstores.barmancloud.cnpg.io -A -o yaml > /tmp/objectstores.yaml

+
+## Known Issues and Limitations
+
+### Current Known Issues
+
+1. **Migration compatibility**: After migrating from in-tree backup to the
+   plugin, the `kubectl cnpg backup` command syntax has changed
+   ([#353](https://github.com/cloudnative-pg/plugin-barman-cloud/issues/353)):
+
+   ```sh
+   # Old command (in-tree, no longer works after migration)
+   kubectl cnpg backup -n <namespace> <cluster-name> \
+     --method=barmanObjectStore
+   
+   # New command (plugin-based)
+   kubectl cnpg backup -n <namespace> <cluster-name> \
+     --method=plugin --plugin-name=barman-cloud.cloudnative-pg.io
+   ```
+
+### Plugin Limitations
+
+1. **Installation method**: Currently only supports manifest and Kustomize
+   installation ([#351](https://github.com/cloudnative-pg/plugin-barman-cloud/issues/351) -
+   Helm chart requested)
+
+2. **Sidecar resource sharing**: The plugin sidecar container shares pod
+   resources with PostgreSQL
+
+3. **Plugin restart behavior**: Restarting the sidecar container requires
+   restarting the entire PostgreSQL pod
+
+## Recap of General Debugging Steps
+
+### Check Backup Status and Identify the Target Instance
+
+```sh
+# List all backups and their status
+kubectl get backups.postgresql.cnpg.io -n <namespace>
+
+# Get detailed backup information including error messages and target instance
+kubectl describe backups.postgresql.cnpg.io \
+  -n <namespace> <backup-name>
+
+# Extract the target pod name from a failed backup
+kubectl get backups.postgresql.cnpg.io \
+  -n <namespace> <backup-name> \
+  -o jsonpath='{.status.instanceID.podName}'
+
+# Get more details including the target pod, method, phase, and error
+kubectl get backups.postgresql.cnpg.io \
+  -n <namespace> <backup-name> \
+  -o jsonpath='Pod: {.status.instanceID.podName}{"\n"}Method: {.status.method}{"\n"}Phase: {.status.phase}{"\n"}Error: {.status.error}{"\n"}'
+
+# Check the cluster status for backup-related information
+kubectl cnpg status <cluster-name> -n <namespace> --verbose
+```
+
+### Check Sidecar Logs on the Backup Target Pod
+
+```sh
+# Identify which pod was the backup target (from the previous step)
+TARGET_POD=$(kubectl get backups.postgresql.cnpg.io \
+  -n <namespace> <backup-name> \
+  -o jsonpath='{.status.instanceID.podName}')
+echo "Backup target pod: $TARGET_POD"
+
+# Check the sidecar logs on the specific target pod
+kubectl logs -n <namespace> $TARGET_POD \
+  -c plugin-barman-cloud --tail=100
+
+# Follow the logs in real time
+kubectl logs -n <namespace> $TARGET_POD \
+  -c plugin-barman-cloud -f
+
+# Check for specific errors in the target pod around the backup time
+kubectl logs -n <namespace> $TARGET_POD \
+  -c plugin-barman-cloud --since=10m | grep -E "ERROR|FATAL|panic|failed"
+
+# Alternative: List all cluster pods and their roles
+kubectl get pods -n <namespace> -l cnpg.io/cluster=<cluster-name> \
+  -o custom-columns=NAME:.metadata.name,ROLE:.metadata.labels.cnpg\\.io/instanceRole,INSTANCE:.metadata.labels.cnpg\\.io/instanceName
+
+# Check sidecar logs on ALL cluster pods (if the target is unclear)
+for pod in $(kubectl get pods -n <namespace> -l cnpg.io/cluster=<cluster-name> -o name); do
+  echo "=== Checking $pod ==="
+  kubectl logs -n <namespace> $pod -c plugin-barman-cloud \
+    --tail=20 | grep -i error || echo "No errors found"
+done
+```
+
+### Check Events for Backup-Related Issues
+
+```sh
+# Check events for the cluster
+kubectl get events -n <namespace> \
+  --field-selector involvedObject.name=<cluster-name>
+
+# Check events for failed backups
+kubectl get events -n <namespace> \
+  --field-selector involvedObject.kind=Backup
+
+# Get all recent events in the namespace
+kubectl get events -n <namespace> --sort-by='.lastTimestamp' | tail -20
+```
+
+### Verify `ObjectStore` Configuration
+
+```sh
+# Check the ObjectStore resource
+kubectl get objectstores.barmancloud.cnpg.io \
+  -n <namespace> <objectstore-name> -o yaml
+
+# Verify the secret exists and has the correct keys
+kubectl get secret -n <namespace> <secret-name> -o yaml
+# Alternatively
+kubectl get secret -n <namespace> <secret-name> -o jsonpath='{.data}' | jq 'keys'
+```
+
+### Common Error Messages and Solutions
+
+* **"AccessDenied" or "403 Forbidden"** — Check cloud credentials and bucket permissions.
+* **"NoSuchBucket"** — Verify the bucket exists and the endpoint URL is correct.
+* **"Connection timeout"** — Check network connectivity and firewall rules.
+* **"SSL certificate problem"** — For self-signed certificates, verify the CA bundle configuration.

+# Using the Barman Cloud Plugin
+
+<!-- SPDX-License-Identifier: CC-BY-4.0 -->
+
+After [installing the plugin](installation.mdx) in the same namespace as the
+CloudNativePG operator, enabling your PostgreSQL cluster to use the Barman
+Cloud Plugin involves just a few steps:
+
+- Defining the object store containing your WAL archive and base backups, using
+  your preferred [provider](object_stores.md)
+- Instructing the Postgres cluster to use the Barman Cloud Plugin
+
+From that moment, you’ll be able to issue on-demand backups or define a backup
+schedule, as well as rely on the object store for recovery operations.
+
+The rest of this page details each step, using MinIO as object store provider.
+
+## Defining the `ObjectStore`
+
+An `ObjectStore` resource must be created for each object store used in your
+PostgreSQL architecture. Here's an example configuration using MinIO:
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: minio-store
+spec:
+  configuration:
+    destinationPath: s3://backups/
+    endpointURL: http://minio:9000
+    s3Credentials:
+      accessKeyId:
+        name: minio
+        key: ACCESS_KEY_ID
+      secretAccessKey:
+        name: minio
+        key: ACCESS_SECRET_KEY
+    wal:
+      compression: gzip
+```
+
+The `.spec.configuration` schema follows the same format as the
+[in-tree barman-cloud support](https://pkg.go.dev/github.com/cloudnative-pg/barman-cloud/pkg/api#BarmanObjectStoreConfiguration).
+Refer to [the CloudNativePG documentation](https://cloudnative-pg.io/documentation/preview/backup_barmanobjectstore/)
+for additional details.
+
+:::important
+The `serverName` parameter in the `ObjectStore` resource is retained solely for
+API compatibility with the in-tree `barmanObjectStore` and must always be left empty.
+When needed, use the `serverName` plugin parameter in the Cluster configuration instead.
+:::
+
+## Configuring WAL Archiving
+
+Once the `ObjectStore` is defined, you can configure your PostgreSQL cluster
+to archive WALs by referencing the store in the `.spec.plugins` section:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+metadata:
+  name: cluster-example
+spec:
+  instances: 3
+  imagePullPolicy: Always
+  plugins:
+  - name: barman-cloud.cloudnative-pg.io
+    isWALArchiver: true
+    parameters:
+      barmanObjectName: minio-store
+  storage:
+    size: 1Gi
+```
+
+This configuration enables both WAL archiving and data directory backups.
+
+## Performing a Base Backup
+
+Once WAL archiving is enabled, the cluster is ready for backups. Backups can be
+created either declaratively (with YAML manifests) or imperatively (with the
+`cnpg` plugin).
+
+### Declarative approach (YAML manifest)
+
+Create a backup resource by applying a YAML manifest:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Backup
+metadata:
+  name: backup-example
+spec:
+  cluster:
+    name: cluster-example
+  method: plugin
+  pluginConfiguration:
+    name: barman-cloud.cloudnative-pg.io
+```
+
+### Imperative approach (using the `cnpg` plugin)
+
+The quickest way to trigger an on-demand backup is with the `cnpg` plugin:
+
+```bash
+kubectl cnpg backup -n <namespace> <cluster-name> \
+  --method=plugin \
+  --plugin-name=barman-cloud.cloudnative-pg.io
+```
+
+:::note Migration from in-tree backups
+If you are migrating from the in-tree backup system, note the change in syntax:
+
+```bash
+# Old command (in-tree backup)
+kubectl cnpg backup -n <namespace> <cluster-name> --method=barmanObjectStore
+
+# New command (plugin-based backup)
+kubectl cnpg backup -n <namespace> <cluster-name> \
+  --method=plugin \
+  --plugin-name=barman-cloud.cloudnative-pg.io
+```
+:::
+
+## Restoring a Cluster
+
+To restore a cluster from an object store, create a new `Cluster` resource that
+references the store containing the backup. Below is an example configuration:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+metadata:
+  name: cluster-restore
+spec:
+  instances: 3
+  imagePullPolicy: IfNotPresent
+  bootstrap:
+    recovery:
+      source: source
+  externalClusters:
+  - name: source
+    plugin:
+      name: barman-cloud.cloudnative-pg.io
+      parameters:
+        barmanObjectName: minio-store
+        serverName: cluster-example
+  storage:
+    size: 1Gi
+```
+
+:::important
+The above configuration does **not** enable WAL archiving for the restored cluster.
+:::
+
+To enable WAL archiving for the restored cluster, include the `.spec.plugins`
+section alongside the `externalClusters.plugin` section, as shown below:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+metadata:
+  name: cluster-restore
+spec:
+  instances: 3
+  imagePullPolicy: IfNotPresent
+  bootstrap:
+    recovery:
+      source: source
+  plugins:
+  - name: barman-cloud.cloudnative-pg.io
+    isWALArchiver: true
+    parameters:
+      # Backup Object Store (push, read-write)
+      barmanObjectName: minio-store-bis
+  externalClusters:
+  - name: source
+    plugin:
+      name: barman-cloud.cloudnative-pg.io
+      parameters:
+        # Recovery Object Store (pull, read-only)
+        barmanObjectName: minio-store
+        serverName: cluster-example
+  storage:
+    size: 1Gi
+```
+
+The same object store may be used for both transaction log archiving and
+restoring a cluster, or you can configure separate stores for these purposes.
+
+## Configuring Replica Clusters
+
+You can set up a distributed topology by combining the previously defined
+configurations with the `.spec.replica` section. Below is an example of how to
+define a replica cluster:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+metadata:
+  name: cluster-dc-a
+spec:
+  instances: 3
+  primaryUpdateStrategy: unsupervised
+
+  storage:
+    storageClass: csi-hostpath-sc
+    size: 1Gi
+
+  plugins:
+  - name: barman-cloud.cloudnative-pg.io
+    isWALArchiver: true
+    parameters:
+      barmanObjectName: minio-store-a
+
+  replica:
+    self: cluster-dc-a
+    primary: cluster-dc-a
+    source: cluster-dc-b
+
+  externalClusters:
+  - name: cluster-dc-a
+    plugin:
+      name: barman-cloud.cloudnative-pg.io
+      parameters:
+        barmanObjectName: minio-store-a
+
+  - name: cluster-dc-b
+    plugin:
+      name: barman-cloud.cloudnative-pg.io
+      parameters:
+        barmanObjectName: minio-store-b
+```
+
+## Configuring the plugin instance sidecar
+
+The Barman Cloud Plugin runs as a sidecar container next to each PostgreSQL
+instance pod. It manages backup, WAL archiving, and restore processes.
+
+Configuration comes from multiple `ObjectStore` resources:
+
+1. The one referenced in the
+   `.spec.plugins` section of the `Cluster`. This is the
+   object store used for WAL archiving and base backups.
+2. The one referenced in the external cluster
+   used in the `.spec.replica.source` section of the `Cluster`. This is
+   used by the log-shipping designated primary to get the WAL files.
+3. The one referenced in the
+   `.spec.bootstrap.recovery.source` section of the `Cluster`. Used by
+   the initial recovery job to create the cluster from an existing backup.
+
+You can fine-tune sidecar behavior in the `.spec.instanceSidecarConfiguration`
+of your ObjectStore. These settings apply to all PostgreSQL instances that use
+this object store. Any updates take effect at the next `Cluster` reconciliation,
+and could generate a rollout of the `Cluster`.
+
+```yaml
+apiVersion: barmancloud.cnpg.io/v1
+kind: ObjectStore
+metadata:
+  name: minio-store
+spec:
+  configuration:
+  # [...]
+  instanceSidecarConfiguration:
+    retentionPolicyIntervalSeconds: 1800
+    resources:
+      requests:
+        memory: "XXX"
+        cpu: "YYY"
+      limits:
+        memory: "XXX"
+        cpu: "YYY"
+```
+
+:::note
+If more than one `ObjectStore` applies, the `instanceSidecarConfiguration` of
+the one set in `.spec.plugins` has priority.
