barman-cloud-backup-delete(1) - Barman-cloud Commands Synopsis 0.0 3.5 barman-cloud-backup-delete [ { -V | --version } ] [ --help ] [ { { -v | --verbose } | { -q | --quiet } } ] [ { -t | --test } ] [ --cloud-provider { aws-s3 | azure-blob-storage | google-cloud-storage } ] [ --endpoint-url ENDPOINT_URL ] [ { -r | --retention-policy } RETENTION_POLICY ] [ { -m | --minimum-redundancy } MINIMUM_REDUNDANCY ] [ { -b | --backup-id } BACKUP_ID] [ --dry-run ] [ { -P | --aws-profile } AWS_PROFILE ] [ --profile AWS_PROFILE ] [ --read-timeout READ_TIMEOUT ] [ { --azure-credential | --credential } { azure-cli | managed-identity | default } ] [--batch-size DELETE_BATCH_SIZE] SOURCE_URL SERVER_NAME 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: 0.0 (bu 2 The WALs predate the begin_wal value of the oldest remaining backup. (bu 2 The WALs are not required by any archival backups stored in the cloud. NOTE: 0.0 3.5 For GCP, only authentication with GOOGLE_APPLICATION_CREDENTIALS env is supported. IMPORTANT: 0.0 3.5 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 0.0 SERVER_NAME Name of the server that holds the backup to be deleted. SOURCE_URL URL of the cloud source, such as a bucket in AWS S3. For example: s3://bucket/path/to/folder. -V / --version Show version 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 The cloud provider to use as a storage backend. Allowed options are: 7.0 (bu 2 aws-s3. (bu 2 azure-blob-storage. (bu 2 google-cloud-storage. -b / --backup-id ID of the backup to be deleted. You can use a shortcut instead of the backup ID. -m / --minimum-redundancy The minimum number of backups that should always be available. -r / --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 } --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). --dry-run Find the objects which need to be deleted but do not delete them. Extra options for the AWS cloud provider 0.0 --endpoint-url Override default S3 endpoint URL with the given one. -P / --aws-profile Profile name (e.g. INI section in AWS credentials file). --profile (deprecated) Profile name (e.g. INI section in AWS credentials file)

barman-cloud-backup-keep(1) - Barman-cloud Commands Synopsis 0.0 3.5 barman-cloud-backup-keep [ { -V | --version } ] [ --help ] [ { { -v | --verbose } | { -q | --quiet } } ] [ { -t | --test } ] [ --cloud-provider { aws-s3 | azure-blob-storage | google-cloud-storage } ] [ --endpoint-url ENDPOINT_URL ] [ { -P | --aws-profile } AWS_PROFILE ] [ --profile AWS_PROFILE ] [ --read-timeout READ_TIMEOUT ] [ { --azure-credential | --credential } { azure-cli | managed-identity | default } ] [ { { -r | --release } | { -s | --status } | --target { full | standalone } } ] SOURCE_URL SERVER_NAME BACKUP_ID Description Use this script to designate backups in cloud storage as archival backups, ensuring their indefinite retention regardless of retention policies. This script allows you to mark backups previously created with barman-cloud-backup as archival backups. Once flagged as archival, these backups are preserved indefinitely and are not subject to standard retention policies. NOTE: 0.0 3.5 For GCP, only authentication with GOOGLE_APPLICATION_CREDENTIALS env is supported. Parameters 0.0 SERVER_NAME Name of the server that holds the backup to be kept. SOURCE_URL URL of the cloud source, such as a bucket in AWS S3. For example: s3://bucket/path/to/folder. BACKUP_ID The ID of the backup to be kept. You can use a shortcut instead of the backup ID. -V / --version Show version 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 The cloud provider to use as a storage backend. Allowed options are: 7.0 (bu 2 aws-s3. (bu 2 azure-blob-storage. (bu 2 google-cloud-storage. -r / --release If specified, the command will remove the keep annotation and the backup will be eligible for deletion. -s / --status Print the keep status of the backup. --target Specify the recovery target for this backup. Allowed options are: 7.0 (bu 2 full (bu 2 standalone Extra options for the AWS cloud provider 0.0 --endpoint-url Override default S3 endpoint URL with the given one. -P / --aws-profile Profile name (e.g. INI section in AWS credentials file). --profile (deprecated) Profile name (e.g. INI section in AWS credentials file)

barman-cloud-restore(1) - Barman-cloud Commands Synopsis 0.0 3.5 barman-cloud-restore [ { -V | --version } ] [ --help ] [ { { -v | --verbose } | { -q | --quiet } } ] [ { -t | --test } ] [ --cloud-provider { aws-s3 | azure-blob-storage | google-cloud-storage } ] [ --endpoint-url ENDPOINT_URL ] [ { -P | --aws-profile } AWS_PROFILE ] [ --profile AWS_PROFILE ] [ --read-timeout READ_TIMEOUT ] [ { --azure-credential | --credential } { azure-cli | managed-identity | default } ] [ --snapshot-recovery-instance SNAPSHOT_RECOVERY_INSTANCE ] [ --snapshot-recovery-zone GCP_ZONE ] [ --aws-region AWS_REGION ] [ --gcp-zone GCP_ZONE ] [ --azure-resource-group AZURE_RESOURCE_GROUP ] [ --tablespace NAME:LOCATION [ --tablespace NAME:LOCATION ... ] ] [ --target-lsn LSN ] [ --target-time TIMESTAMP ] [ --target-tli TLI ] SOURCE_URL SERVER_NAME BACKUP_ID RECOVERY_DESTINATION Description Use this script to restore a backup directly from cloud storage that was created with the barman-cloud-backup command. Additionally, this script can prepare for recovery from a snapshot backup by verifying that attached disks were cloned from the correct snapshots and by downloading the backup label from object storage. This command does not automatically prepare Postgres for recovery. You must manually manage any %PITR options, custom restore_command values, signal files, or required WAL files to ensure Postgres starts, either manually or using external tools. NOTE: 0.0 3.5 For GCP, only authentication with GOOGLE_APPLICATION_CREDENTIALS env is supported. Parameters 0.0 SERVER_NAME Name of the server that holds the backup to be restored. SOURCE_URL URL of the cloud source, such as a bucket in AWS S3. For example: s3://bucket/path/to/folder. BACKUP_ID The ID of the backup to be restored. You can use a shortcut instead of the backup ID. Besides that, you can use auto to have Barman automatically find the most suitable backup for the restore operation. RECOVERY_DESTINATION The path to a directory for recovery. -V / --version Show version 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 The cloud provider to use as a storage backend. Allowed options are: 7.0 (bu 2 aws-s3. (bu 2 azure-blob-storage.
