    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

Name of the server in barman node
Id of the backup in barman catalog.
Destination directory to restore the backup.
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.
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.
Specify the maximum transfer rate in kilobytes per second. A value of 0 indicates no limit. This setting overrides the bandwidth_limit configuration option.
Set target (time, XID or LSN) to be non inclusive.
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.
Enable/disable usage of get-wal for WAL fetching during recovery. Default is based on recovery_options setting.
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.
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.
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.
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.
Enable/disable network compression during remote restore. Default is based on network_compression configuration setting.
There will be no retry in case of an error. It is the same as setting --retry-times 0.
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).
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.
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'.
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.
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.
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.
Whether to start the Postgres server as a standby.
Specify tablespace relocation rule. NAME is the tablespace name and LOCATION is the recovery host destination path to restore the tablespace.
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.

Recovery is completed when a consistent state is reached (end of the base backup).
Recover to the specified LSN (Log Sequence Number). Requires Postgres 10 or above.
Recover to the specified name of a restore point previously created with the pg_create_restore_point(name).
Recover to the specified time. Use the format YYYY-MM-DD HH:MM:SS.mmm.
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.
Recover to the specified transaction ID.

SHORTCUTS

Use shortcuts instead of BACKUP_ID.

Shortcut Description
first/oldest Oldest available backup for the server, in chronological order.
last/latest Most recent available backup for the server, in chronological order.
last-full/latest-full Most recent full backup eligible for a block-level incremental backup using the --incremental option.
last-failed Most recent backup that failed, in chronological order.
