    SERVER_NAME BACKUP_ID DESTINATION_DIR

Description#

Execute a PostreSQL server restore operation. Barman will restore the backup from a server in the destination directory. The restoration can be performed locally (on the barman node itself) or remotely (on another machine accessible via SSH). The location is determined by whether or not the --remote-ssh-command option is used. More information on this command can be found in the Recovery section. You can use a shortcut instead of BACKUP_ID.

Parameters#

SERVER_NAME

Name of the server in barman node

BACKUP_ID

Id of the backup in the barman catalog. Use auto to have Barman automatically find the most suitable backup for the restore operation.

DESTINATION_DIR

Destination directory to restore the backup.

--aws-region

Specify the AWS region where the instance and disks for snapshot recovery are located. This option allows you to override the aws_region value in the Barman configuration.

--azure-resource-group

Specify the Azure resource group containing the instance and disks for snapshot recovery. This option allows you to override the azure_resource_group value in the Barman configuration.

--bwlimit

Specify the maximum transfer rate in kilobytes per second. A value of 0 indicates no limit. This setting overrides the bandwidth_limit configuration option.

--exclusive

Set target (time, XID or LSN) to be non inclusive.

--gcp-zone

Specify the GCP zone where the instance and disks for snapshot recovery are located. This option allows you to override the gcp_zone value in the Barman configuration.

--get-wal / --no-get-wal

Enable/disable usage of get-wal for WAL fetching during recovery. Default is based on recovery_options setting.

-h / --help

Show a help message and exit. Provides information about command usage.

-j / --jobs

Specify the number of parallel workers to use for copying files during the backup. This setting overrides the parallel_jobs parameter if it is specified in the configuration file.

--jobs-start-batch-period

Specify the time period, in seconds, for starting a single batch of jobs. This value overrides the parallel_jobs_start_batch_period parameter if it is set in the configuration file. The default is 1 second.

--jobs-start-batch-size

Specify the maximum number of parallel workers to initiate in a single batch. This value overrides the parallel_jobs_start_batch_size parameter if it is defined in the configuration file. The default is 10 workers.

--local-staging-path

Specify path on the Barman host where the chain of backups will be combined before being copied to the destination directory. The contents created within the staging path will be removed upon completion of the restore process. This option is necessary for restoring from block-level incremental backups and has no effect otherwise.

--network-compression / --no-network-compression

Enable/disable network compression during remote restore. Default is based on network_compression configuration setting.

--no-retry

There will be no retry in case of an error. It is the same as setting --retry-times 0.

--recovery-conf-filename

Specify the name of the file where Barman should write recovery options when recovering backups for Postgres versions 12 and later. By default, this is set to postgresql.auto.conf. However, if --recovery-conf-filename is specified, recovery options will be written to the specified value instead. While the default value is suitable for most Postgres installations, this option allows you to specify an alternative location if Postgres is managed by tools that alter the configuration mechanism (for example, if postgresql.auto.conf is symlinked to /dev/null).

--recovery-staging-path

Specify a path on the recovery host where files for a compressed backup will be staged before being uncompressed to the destination directory. Backups will be staged in their own directory within the staging path, following the naming convention: barman-staging-SERVER_NAME-BACKUP_ID. This staging directory will be removed after the restore process is complete. This option is mandatory for restoring from compressed backups and has no effect otherwise.

--staging-path

A path where intermediate files are staged during restore. When restoring a compressed backup, it serves as a temporary location for decompression before copying to the final destination. When restoring an incremental backup, it is where backups are combined before copying to the final destination. This location must have enough space to store the decompressed/combined backup.

--staging-location

Specifies whether --staging-path is a local or remote path. Valid values are local and remote.

--remote-ssh-command

This option enables remote restore by specifying the secure shell command to execute on a remote host. It functions similarly to the ssh_command server option in the configuration file for remote restore, that is, 'ssh USER@SERVER'.

--retry-sleep

Specify the number of seconds to wait after a failed copy before retrying. This setting applies to both backup and restore operations and overrides the basebackup_retry_sleep parameter if it is defined in the configuration file.

--retry-times

Specify the number of times to retry the base backup copy in case of an error. This applies to both backup and restore operations and overrides the basebackup_retry_times parameter if it is set in the configuration file.

--snapshot-recovery-instance

Specify the name of the instance where the disks recovered from the snapshots are attached. This option is necessary when recovering backups created with backup_method=snapshot.

--snapshot-recovery-zone (deprecated)

Zone containing the instance and disks for the snapshot recovery (deprecated: replaced by --gcp-zone)

--standby-mode

Whether to start the Postgres server as a standby.

--tablespace

Specify tablespace relocation rule. NAME is the tablespace name and LOCATION is the recovery host destination path to restore the tablespace.

--target-action

Trigger the specified action when the recovery target is reached. This option requires defining a target along with one of these actions. The possible values are:

  • pause: Once recovery target is reached, the server is started in pause state, allowing users to inspect the instance

  • promote: Once recovery target is reached, the server will exit the recovery operation and is promoted as a master.

  • shutdown: Once recovery target is reached, the server is shut down.

--target-immediate

Recovery is completed when a consistent state is reached (end of the base backup).

--target-lsn

Recover to the specified LSN (Log Sequence Number). Requires Postgres 10 or above.

--target-name

Recover to the specified name of a restore point previously created with the pg_create_restore_point(name).

--target-time

Recover to the specified time. Use the format YYYY-MM-DD HH:MM:SS.mmm.

--target-tli

Recover the specified timeline. You can use the special values current and latest in addition to a numeric timeline ID. For Postgres versions 12 and above, the default is to recover to the latest timeline in the WAL archive. For Postgres versions below 12, the default is to recover to the timeline that was current at the time the backup was taken.

--target-xid

Recover to the specified transaction ID.

--staging-wal-directory

A staging directory on the destination host for WAL files when performing PITR. If unspecified, it uses a barman_wal directory inside the destination directory.
