SERVICES

Descriptions and parameters of available services.

retention

Fail when the number of full backups is less than the --retention-full argument.

Fail when the newest backup is older than the --retention-age argument.

Fail when the newest full backup is older than the --retention-age-to-full argument.

The following units are accepted (not case sensitive): s (second), m (minute), h (hour), d (day). You can use more than one unit per given value.

Arguments are not mandatory to only show some information.

archives

Check if all archived WALs exist between the oldest and the latest WAL needed for the recovery.

Archives must be compressed. If needed, use "compress-level=0" instead of "compress=n".

Use the --wal-segsize argument to set the WAL segment size.

The following units are accepted (not case sensitive): b (Byte), k (KB), m (MB), g (GB), t (TB), p (PB), e (EB) or Z (ZB). Only integers are accepted. Eg. 1.5MB will be refused, use 1500kB.

The factor between units is 1024 bytes. Eg. 1g = 1G = 1024*1024*1024.

Use the --ignore-archived-before argument to ignore the archived WALs generated before the provided interval. Used to only check the latest archives.

Use the --ignore-archived-after argument to ignore the archived WALs generated after the provided interval.

The --latest-archive-age-alert argument defines the max age of the latest archived WAL as an interval before raising a critical alert.

The following units are accepted as interval (not case sensitive): s (second), m (minute), h (hour), d (day). You can use more than one unit per given value. If not set, the last unit is in seconds. Eg. "1h 55m 6" = "1h55m6s".

All the missing archives are only shown in the --debug mode.

Use --list-archives in addition with --debug to print the list of all the archived WAL segments.

By default, all the archives older than the oldest backup start archive or newer than the max_wal returned by the pgBackRest info command are ignored.

Use the --extended-check argument to force a full check of the found archives and raise warnings in case of inconsistencies.

check_pgb_version

Check if this script is running a given version.

You must provide the expected version using --target-version.
