Description#

Execute a PostreSQL server backup. Barman will use the parameters specified in the Global and Server configuration files. Specify all shortcut instead of the server name to execute backups from all servers configured in the Barman node. You can also specify multiple server names in sequence to execute backups for specific servers.

Parameters#

SERVER_NAME

Name of the server in barman node.

--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.

-h / --help

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

--incremental

Execute a block-level incremental backup. You must provide a BACKUP_ID or a shortcut to a previous backup, which will serve as the parent backup for the incremental backup.

Note

The backup to be and the parent backup must have backup_method=postgres.

--immediate-checkpoint

Forces the initial checkpoint to be executed as soon as possible, overriding any value set for the immediate_checkpoint parameter in the configuration file.

-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's 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.

--keepalive-interval

Specify an interval, in seconds, for sending a heartbeat query to the server to keep the libpq connection active during a Rsync backup. The default is 60 seconds. A value of 0 disables the heartbeat.

--manifest

Forces the creation of a backup manifest file upon completing a backup. Overrides the autogenerate_manifest parameter from the configuration file. Applicable only to rsync backup strategy.

--name

Specify a friendly name for this backup which can be used in place of the backup ID in barman commands.

--no-immediate-checkpoint

Forces the backup to wait for the checkpoint to be executed overriding any value set for the immediate_checkpoint parameter in the configuration file.

--no-manifest

Disables the automatic creation of a backup manifest file upon completing a backup. This setting overrides the autogenerate_manifest parameter from the configuration file and applies only to rsync backup strategy.

--no-retry

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

--retry-sleep

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

--reuse-backup

Overrides the behavior of the reuse_backup option configured in the configuration file. The possible values are:

  • off: Do not reuse the last available backup.

  • copy: Reuse the last available backup for a server and create copies of unchanged files (reduces backup time).

  • link (default): Reuse the last available backup for a server and create hard links to unchanged files (saves both backup time and space).

Note

This will only have any effect if the last available backup was executed with backup_method=rsync.

--wait / -w

Wait for all necessary WAL files required by the base backup to be archived.

--wait-timeout

Specify the duration, in seconds, to wait for the required WAL files to be archived before timing out.
