Shut down Server after backup
- Thread starter jonasled

Hi, there are several ways to do this, depends on how clever and complex you want the script to be.
I'll give you the way that I set it up. I just wanted it to be straight forward, therefor excepting that it is not an intelligent script that monitors the end time of a backup job f.e.
Knowing how long my maximum backup time would be (including new dirty bitmaps, so full backup) I set a cron script in my PBS at a specified time to shut it down.
Additionally for PVE:
While your PBS is down, PVE wil generate a lot of error messages, because the pbs storage isn't available for PVE.
So I set up a cron script in PVE that enables the pbs storage just before the backup starts, and disables just before pbs is shutdown
I also have wakeonlan package installed (etherwake is also possible) to wakeup PBS from PVE.
And at the end because my PBS uses ZFS, I wake up PBS for the preconfigured cron job for ZFS scrubbing every month.
The scripts can be placed on the corresponding hosts in
These scripts are of course examples to get you started, you have to adjust values to your own preferences and maintenance windows.
