Pre & Post Backup Programs
When a backup job using a profile containing client pre-backup or post-backup programs is run, the system
will attempt to execute the specified program on each client before or after that client backup is performed.
If the program does not exist on any client or is not executable, it will be ignored. Otherwise, it will be
executed and one of the following actions will be taken depending on the exit code of the program:

A post-backup program will be executed even if the backup command that precedes
it fails. This is necessary in case the post-backup program must record information
about the backup or restart processes that were stopped by the pre-backup program.
Pre & Post Snapshot Programs
When a backup job using a profile containing pre-snapshot and post-snapshot programs is run, the system
will attempt to execute the specified program on each client before and/or after each snapshot is created.
The program will only be executed for the storage containers to be included in the backup, and if Snapshot
Backups have been configured and the Backup Job is configured to perform snapshot backups.
The program names provided will be executed before a snapshot is created for each
logical volume/filesystem
. Therefore, the program must be intelligent enough to
recognize the name of the logical volume or filesystem the snapshot is being created
for at that time and act accordingly (or do nothing). Refer to
Creating Pre and Post
Backup Programs below for more information.
If the specified program does not exist on any client or is not executable, it will be ignored. Otherwise, it will
be executed and one of the following actions will be taken depending on the exit code of the program:
Pre-snapshot Program Post-snapshot Program
Exit code 0
The snapshot of the logical volume will
be created and the backup will
continue.
Backup will continue normally.
Exit code 1
The snapshot will not be created for the
logical volume and the backup will
terminate.
The backup will terminate with an error.
Exit code 2
The snapshot will not be created for the
logical volume, and the backup will
continue using the active (online) data.
The backup will terminate with an error.
Exit code 3
or higher
A warning message will appear, but the
snapshot will be created and the
backup will continue normally.
The backup will terminate with an error.
