Question regarding sync jobs

Question regarding sync jobs

[Fabrizio Cuseo]

Hello.
I have searched with no results, so I ask if is possibile:

- several PBS servers with backups for different PVE clusters
- remote PBS server that handles USB drives for remote ad offline backup sync
- several sync jobs for each USB drive repository; this is needed because a single USB drive contains different remote PBS sources.

If I flag "execute on mount", and "unmount after synced" on a single script, no problems. But If have more than one sync job, I would like to have a sequence, so:
- first job, "executed on mount"
- second job, "executed after first"
- third job, "executed after second" - "unmount at end".

Is this possible or scheduled for a next release ? 

Thanks, Fabrizio

this is what should be happening, if you have multiple jobs marked with
"run on mount" they should run sequentially(ordered by job-id)[1], and
if any of the jobs has "unmount after" set the datastore will be
unmounted after the last one finishes.

If this is not happening, it's a bug :)
