Re: [Bacula-users] Deleting DIFFERENTIAL Jobs from Volumes

Hello again,

A new question : Is there a way I can set up Bacula so that it recycles only the differential jobs from a volume? For example, I have one volume that has the initial full backup in it and 1 other differential job. Can I set it up so that only the differential job in there gets recycled every hour?

This case is not possible, because all backup (Full and Differential) are in the same volume, if you recycle volume, bacula will recycle entire volume.

OR, say i have the flag "User Volume _Once_ = yes", and I have 1 volume which is the first full backup, then 1 other volume which represents the differential backup, can I set up recycling only on the 2nd volume? I don't want to be doing a full backup every hour because of retention times, and I only want to do a full backup ONCE, then only differential.

Yes. You need to create a Pool for the Full backups with a long retention and another Pool for the Differential backups with a shorter retention.

I have tried this (without the Use Volume Once flag) with a 3 hour retention period (since it takes about 2 and a half hours to do a full backup for my filesystem, and if I set the retention period lower than that then bacula runs the next differential job(which is hourly) as a full job...) and the problem is that after those 3 hours are up bacula creates a new full job in the first volume, since it sees it as being expired.

I can't seem to figure out a decent plan using Bacula for my specific needs, it's driving me crazy.
