Subject: Re: [Bacula-users] Which full back up is an
incremental/differential back up based on if multiple full back ups
exist within multiple pools with different retention periods?
To: John Drescher <drescherjm AT gmail DOT com>


Makes perfect sense. I was operating under the wrong impression before
that they were calculated from the same timestamp which is why
rentention and Volume Use Duration were the same value. I'm going to
keep the volume use durations the same, and significantly lower the
retention periods to force the volumes to recycle very soon after
Volume use duration marks them as used.

You've been a great help so far and made me realize I need to redo my
configs. What about my original question though? Does bacula look
within a specific volume for the latest full back up and use that, or
does it simply grab the newest one from the jobID? My concern was
incremental/differential backups with a longer volume use
duration/retention period than the full back ups that they may be
based upon.
