Dwight's response about getting info from accounting records is the best,
detailed info source for backup, archive, and HSM usage.  You should
also consider gathering such information over time.  Simple ways to do
that are to do Query STGpool each day to watch growth; and just count
the number of scratch tapes you have left after each day, which is
a good empirical way of gauging how many tapes are needed per day.
