+### S3 Lifecycle Policy
+
+Barman Cloud requires the following permissions in the S3 bucket:
+
+- [`s3:AbortMultipartUpload`](https://docs.aws.amazon.com/AmazonS3/latest/API/API_AbortMultipartUpload.html)
+- [`s3:DeleteObject`](https://docs.aws.amazon.com/AmazonS3/latest/API/API_DeleteObject.html)
+- [`s3:GetObject`](https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObject.html)
+- [`s3:ListBucketMultipartUploads`](https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListMultipartUploads.html)
+- [`s3:ListBucket`](https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListBuckets.html)
+- [`s3:ListMultipartUploadParts`](https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListParts.html)
+- [`s3:PutObject`](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutObject.html)
