Hi Arno, thanks for your answer.

[...] I prefer to do it like this:- Define a pool for full backups (in your case, for the monthly fulls to go to the vault). - After the scheduled jobs run, make sure all the volumes just used are no longer appendable. This can be achieved by setting a limited volume use time and forcing Bacula to consider the pool in questio n when looking for usable volumes, by using the bconsole command 'update volume', or accessong the catalog database directly. Basically, what I'm usually doing is using a script that looks for volumes loaded in the autochanger, which were used recently, and are in status "Append" and set those to "Used".- Then, just unload all the volumes from that pool and store them safely.
So would the following pool definition:
Pool {
Name = Monthly
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Use Duration = 8h
Volume Retention = 360 days
}
be enough, or do I need some script on top of that?
Loading the next usable volumes is rather straightforward done manually... Just select the next set uf tapes, and load them to the autochanger. If you've ensured the retention periods are set up correctly (i.e., less than a year - 11 months should be ok) the volumes usable will automatically be chosen when the next jobs are running.
I don't have an autochanger. Our full backups still fit on one tape. (Lucky, aren't we?) So I translate this for my purposes to: "Just insert the next month's tape at the appropriate time and Bacula will use it." Correct?
The most important thing, in my opinion, is not to rely on volume names but rather to use Baculas front-end to select which volumes to use.
That's ok. It's just that when Bacula sends its mail "please insert tape X" it's too late, the operator has gone home. I need a way to anticipate which tape Bacula will ask for, so it can be inserted ahead of time while there's still someone working. With our old backup system, we had a simple static paper calendar telling the operator which tape to insert each day. Now Bacula decides dynamically which tape it wants next, so I need a way for it to tell our operator which one it will be.
Choosing the volumes to load would then only require a catalog query which prints the volume names of the volumes from the relavnt pool which were written to 11 months or more ago, or, more useful, the ones that will be out of their retention time at the next backup runs.
I must admit I wouldn't know how to do that. Where do I find information writing catalog queries? Can they be scripted, so I can set up a cron job sending my operator a daily mail "insert tape X"?
