On versions 2.1.4 or greater, Bacula can recycle media in the pool of
your choice. The most useful setup is to use Scratch.
Version 2.1.4 is not quite right ;-). This option is under rework by Kern just
at the moment so it will hopefully be usable with next release (2.1.26 (beta
version) or 2.2.0 (release version))

This is one of the points, which are changing at the moment ;-)
But in general bacula will try to prune volumes only when absolutely necessary
and prefer the requested pool. So it will most likely use volumes from the
"wrong" pool only when there are no usable volumes in neither the "correct"
pool nor the scratch pool.

Also it might be nice this is not a (main) feature of the pruning algorithm.
But improving the tapemanagement is on the wishlist for bacula (see Item 25 on
the projekts-list: http://www.bacula.org/?page=projects )
