Hello,
When I first started using bacula about 5 months ago, I used one
volume for everything. All seemed to be fine until I realized how
quickly I was going to use up the 2.5 terabytes. At the time, I
wrongly assumed six months would pass and I would have plenty of space
after the volume was recycled.
Now, I have very little space left. I've split each backup into their
own pools (as described in
http://www.bacula.org/dev-manual/Automated_Disk_Backup.html) and the
large volume is no longer being written to as of the first week of
May. If I understand the documentation correctly I can recapture hard
drive space like this:
Change the VolRetention period to three months instead of six (which I did)
Set Autoprune and Recycle to Yes
I'm hoping the VolRetention is measured from when the volume was first
used, which is back in January or February, and that even though the
available disk space on the bacula server shows less than 100 gb left,
it will overwrite space that has been taken up by the single large
volume when another volume needs the space.
That is essentially my question. If I understand correctly, since
bacula holds on to data as long is it can until more space is needed,
will the bacula server at some point, always have a full hard drive?
If I'm wrong, when does it clear the space taken by expired retention
periods? I wonder what options I have to save the last three months
of backups from the large volume while removing the backups whose time
has expired. Is there a way to do this? Or do I need to just remove
the large volume to make more space? Thank you for any tips.
