Hi Peter,

 

Bacula will always prefer to take a new volume (in Append state) rather than reuse an existing one (in the Purged, Recycled state) so as to preserve your backed up data for as long as possible. It will also use volumes in the backup pool and only resort to taking volumes from the Scratch pool when there are none suitable for writing in the pool.

 

I’m not entirely certain which of those two criteria will win out; I think purged volumes in the backup pool will be used before Bacula tries to use an unused volume from the Scratch pool but you may wish to check this.

 

I can understand why you’d want Bacula to reuse old volumes within one of your backup pools first (so as to maximise the number of volumes left in the scratch pool), but can’t see a reason why you’d prefer to reuse recycled volumes already moved back into the scratch pool before unused ones. If you did mean the latter, perhaps you can reply with your reasoning.

Thank you Ben.

 

I applied the changes and I'll monitor the behavior to confirm I did it right.

 

If I have mix of recycled volumes and brand new, never used volumes in Scratch, which ones Bacula will grab first?

 

I'd really prefer to setup Bacula so it will reuse the old ones instead of grabbing brand new volumes.

Hi Peter,

 

You need to set “Recycle Pool = Scratch” in your Scratch pool (and make sure you haven’t overridden it in any other poo)l. Note that this setting is applied to the volume when it’s created, so after changing the Scratch pool definition you will need to update all your volumes to re-apply the Recycle pool. It might be easiest to do this by directly modifying the catalog, else you can use a quick bash script to generate a sequence of “update volume…” commands to echo into bconsole.

In Bacula-5.2.13 how do I setup expired volumes to go in the Scratch pool?

 

I create new file type volumes like this:

  label storage=File volume=vol001 pool=Scratch

 

When needed volumes are taken out of Scratch and assigned to the appropriate pool and used. Once in the pull they are never released back to Scratch after they expire.

 

After retentionperiod ends volumes are reused but only within the pool they have been originally assigned.

 

I see volume properties that may be related but I can't find documentation about them:

    scratchpoolid: 0

    recyclepoolid: 0

 

Any help in making volumes go in Scratch after retention period expire so they can be reused by any job.

 

Thank you,
