Which brings me to ask more questions :)

If I limit the maximum volumes per pool, and the backup size is hard to
predict, it means that:

        - for large backup sets, I'm going to run out of volumes, and it will
start to recylce volumes which data I still wanted to keep

        - for smaller backup sets, I'm over allocating volume space in the hope
of not running out of volumes, wasting space.

Neither scenario is ideal.  Is there no better way ?
