He is not confused. I think.
The bacula should not to recycle a volume, even if there is not appendable
volumes*.
*The manual says: *"**The Volume Retention record defines the length of time
that Bacula will guarantee that the Volume is not reused** counting from the
time the last job stored on the Volume terminated". *Not mention to jobs on
catalog.
The files and job retention period comes to prevent catalog growing, not to
recycle volumes, says the manual.
*The Volume Retention record defines the length of time that Bacula will
guarantee that the Volume is not reused counting from the time the last job
stored on the Volume terminated. A key point is that this time period is not
even considered as long at the Volume remains appendable. The Volume
Retention period count down begins only when the Append status has been
changed to some othe status (Full, Used, Purged, ...). *
* When this time period expires, and if AutoPrune is set to yes, and a new
Volume is needed, but no appendable Volume is available, Bacula will prune
(remove) Job records that are older than the specified Volume Retention
period. *
* The Volume Retention period takes precedence over any Job Retention period
you have specified in the Client resource. It should also be noted, that the
Volume Retention period is obtained by reading the Catalog Database Media
record rather than the Pool resource record. This means that if you change
the VolumeRetention in the Pool resource record, you must ensure that the
corresponding change is made in the catalog by using the update
poolcommand. Doing so will insure that any new Volumes will be created
with the
changed Volume Retention period. Any existing Volumes will have their own
copy of the Volume Retention period that can only be changed on a Volume by
Volume basis using the update volume command. *
* When all file catalog entries are removed from the volume, its VolStatus
is set to Purged. The files remain physically on the Volume until the volume
is overwritten. *
* Retention periods are specified in seconds, minutes, hours, days, weeks,
months, quarters, or years on the record. See the Configuration chapterTime
of this manual for additional details of time specification. *
* The default is 1 year. *
