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,
etc.
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.
For Linux systems, snapshots are created for LVM logical volumes. For AIX systems,
snapshots are created for JFS2 filesystems. For Solaris systems, snapshots are
create for ZFS datasets.
The program will only be executed for snapshots created and included in the backup, if
have been configured (for the client if using Network Edition), and the
is configured to perform
snapshot backups.
The program names provided will be executed before the snapshot is created for
each snapshot source. Therefore, the program must be intelligent enough to
recognize the name of the device or filesystem the snapshot is being created for at
that time and act accordingly (or do nothing). Refer to
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
