I think what he wants is a way to make sure a tape is closed to, say, start a
week with a fresh tape.
Pretty easy to do with different pools/schedules/jobs actually.

Subject: Re: [Bacula-users] [Bacula-devel] Feature Request: Implement an'Volume
Append Duration' pool directive
Unfortunately, I don't understand the explanation below -- more precisely, I
don't understand what it fixes. Can anyone explain the need for this Feature
Request to me?
I just cannot grasp what it serves to mark a tape Used when it has been unused
for a certain period.
It also seems to me that ANDing together two different directives is a new
concept, which could add complexity to the existing plethera of directives.
Regards,
Kern
