Our Daily pool finally filled up after
a year of writing to it. Our changer was asking to label a volume "Daily-xxxx"
which all of our tapes are L3xxxxxx from bar codes. I figured out that this was
happening because of the directive "Label Format" that I had specified. I
commented out the directive and deleted the virtual media entries from the
database and tried the mount command without specify a slot. It stopped asking
for a volume name, but the said there was no appendable media. I read through
the Automatic Volume Recycling chapter (http://www.bacula.org/en/rel-manual/Automatic_Volume_Recycling.html)
and everything seems to be in place. I've set Autoprune = yes and Recycle = yes
some time ago with a volume retention of 4 months. I've checked all this in
bconsole and everything is correct.
Now, from the
chapter I get from this section:
"By setting AutoPrune to yes you will permit
Bacula to automatically prune all Volumes in the Pool when a Job needs
another Volume. Volume pruning means removing records from the catalog. It does
not shrink the size of the Volume or affect the Volume data until the Volume
gets overwritten. When a Job requests another volume and there are no Volumes
with Volume Status Append available, Bacula will begin volume pruning.
This means that all Jobs that are older than the VolumeRetention period
will be pruned from every Volume that has Volume Status Full or
Used and has Recycle set to yes. Pruning consists of deleting the
corresponding Job, File, and JobMedia records from the catalog database. No
change to the physical data on the Volume occurs during the pruning process.
When all files are pruned from a Volume (i.e. no records in the catalog), the
Volume will be marked as Purged implying that no Jobs remain on the
volume. The Pool records that control the pruning are described
below."
This tells me that
when there are no appendable volumes, bacula will search through the pool and
prune all jobs and files from all media that the last written date is greater
then the VolumeRetention period. This also seems to indicate that this pruning
overrides any retention period that may be set in the client directive. However,
the behavior that I've seen tonight seems to indicate that this is not the case.
Our client directive has the file retention period set to 2 years and the job
retention set for 5 years. We have our back-ups in a GFS rotation and would like
our monthly back-ups to archived for this long. Please advise me how to
know exactly what is going on and set this up the way we would
like.
Thank
you,
