NAME
barman-cloud-backup-delete - Delete backups stored in the Cloud
SYNOPSIS
barman-cloud-backup-delete [OPTIONS] SOURCE_URL SERVER_NAME
DESCRIPTION
This script can be used to delete backups previously made with the barman-cloud-backup command. Current‐
ly AWS S3, Azure Blob Storage and Google Cloud Storage are supported.
The target backups can be specified either using the backup ID (as returned by barman-cloud-backup-list)
or by retention policy. Retention policies are the same as those for Barman server and work as described
in the Barman manual: all backups not required to meet the specified policy will be deleted.
When a backup is successfully deleted any unused WALs associated with that backup are removed. WALs are
only considered unused if:
1. There are no older backups than the deleted backup or all older backups are archival backups.
2. The WALs pre-date the begin_wal value of the oldest remaining backup.
3. The WALs are not required by any archival backups present in cloud storage.
Note: The deletion of each backup involves three separate delete requests to the cloud provider (once for
the backup files, once for the backup.info file and once for any associated WALs). If you have a signif‐
icant number of backups accumulated in cloud storage then deleting by retention policy could result in a
large number of delete requests.
This script and Barman are administration tools for disaster recovery of PostgreSQL servers written in
Python and maintained by EnterpriseDB.

source_url server_name
This script can be used to delete backups made with barman-cloud-backup
command. Currently AWS S3, Azure Blob Storage and Google Cloud Storage are
supported.
positional arguments:
source_url URL of the cloud source, such as a bucket in AWS S3.
For example: `s3://bucket/path/to/folder`.
server_name the name of the server as configured in Barman.
optional arguments:
-V, --version show program's version number and exit
--help show this help message and exit
-v, --verbose increase output verbosity (e.g., -vv is more than -v)
-q, --quiet decrease output verbosity (e.g., -qq is less than -q)
-t, --test Test cloud connectivity and exit
--cloud-provider {aws-s3,azure-blob-storage,google-cloud-storage}
The cloud provider to use as a storage backend
-b BACKUP_ID, --backup-id BACKUP_ID
Backup ID of the backup to be deleted
-m MINIMUM_REDUNDANCY, --minimum-redundancy MINIMUM_REDUNDANCY
The minimum number of backups that should always be available.
-r RETENTION_POLICY, --retention-policy RETENTION_POLICY
If specified, delete all backups eligible for deletion
according to the supplied retention policy. Syntax:
REDUNDANCY value | RECOVERY WINDOW OF value {DAYS |
WEEKS | MONTHS}
--dry-run Find the objects which need to be deleted but do not
delete them
--batch-size DELETE_BATCH_SIZE
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).
Extra options for the aws-s3 cloud provider:
--endpoint-url ENDPOINT_URL
Override default S3 endpoint URL with the given one
-P AWS_PROFILE, --aws-profile AWS_PROFILE
profile name (e.g. INI section in AWS credentials
file)
--profile AWS_PROFILE
profile name (deprecated: replaced by --aws-profile)
--read-timeout READ_TIMEOUT
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-blob-storage cloud provider:
--azure-credential {azure-cli,managed-identity}, --credential {azure-cli,managed-identity}
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.
