Description

The barman-cloud-backup-delete script is used to delete one or more backups created with the barman-cloud-backup command from cloud storage and to remove the associated WAL files.

Backups can be specified for deletion either by their backup ID (as obtained from barman-cloud-backup-list) or by a retention policy. Retention policies mirror those used by the Barman server, deleting all backups that are not required to meet the specified policy. When a backup is deleted, any unused WAL files associated with that backup are also removed.

WALs are considered unused if:

  • The WALs predate the begin_wal value of the oldest remaining backup.
  • The WALs are not required by any archival backups stored in the cloud.

NOTE:

For GCP, only authentication with GOOGLE_APPLICATION_CREDENTIALS env is supported.


IMPORTANT:

Each backup deletion involves three separate requests to the cloud provider: one for the backup files, one for the backup.info file, and one for the associated WALs. Deleting by retention policy may result in a high volume of delete requests if a large number of backups are accumulated in cloud storage.


Parameters

Name of the server that holds the backup to be deleted.
URL of the cloud source, such as a bucket in AWS S3. For example: s3://bucket/path/to/folder.
Show version and exit.
show this help message and exit.
Increase output verbosity (e.g., -vv is more than -v).
Decrease output verbosity (e.g., -qq is less than -q).
Test cloud connectivity and exit.
The cloud provider to use as a storage backend.

Allowed options are:

  • aws-s3.
  • azure-blob-storage.
  • google-cloud-storage.

ID of the backup to be deleted
The minimum number of backups that should always be available.
If specified, delete all backups eligible for deletion according to the supplied retention policy.

Syntax: REDUNDANCY value | RECOVERY WINDOW OF value { DAYS | WEEKS | MONTHS }

The maximum number of objects to be deleted in a single request to the cloud provider. If unset then the maximum allowed batch size for the specified cloud provider will be used (1000 for aws-s3, 256 for azure-blob-storage and 100 for google-cloud-storage).
Find the objects which need to be deleted but do not delete them.

Extra options for the AWS cloud provider

Override default S3 endpoint URL with the given one.
Profile name (e.g. INI section in AWS credentials file).
Profile name (e.g. INI section in AWS credentials file) - replaced by --aws-profile.
The time in seconds until a timeout is raised when waiting to read from a connection (defaults to 60 seconds).

Extra options for the Azure cloud provider

Optionally specify the type of credential to use when authenticating with Azure. If omitted then Azure Blob Storage credentials will be obtained from the environment and the default Azure authentication flow will be used for authenticating with all other Azure services. If no credentials can be found in the environment then the default Azure authentication flow will also be used for Azure Blob Storage.

Allowed options are:

  • azure-cli.
  • managed-identity.
