First of all, I don't think you run Bacula for a year already, and so
you might have missed to update the actual volume information after
you changed the retention times in the pool definitions.
The pool definitions are used as a template when creating new volumes,
they are not automatically applied to existing volumes.
So, if you want to keep your backed up data for about one year, you
should update the existing volumes accordingly... start with 'update
volume=Behemot-0001' and use the menu, for example.

Pruning takes place when, while looking for available volumes, Bacula
finds volumes or jobs that are beyond their retention times.
Basically, the corresponding data is removed from the catalog, so the
volumes is known to hold no more jobs.
Recycling is the process or actually marking a volume in the catalog
to be reusable. Recycled volumes will typically be used and
overwritten (or truncated, for file volumes) immediately.
Hope this helps you,
