Eric,

What is the recommended volume size.  I have seen someone mentioned 5G, but then
the number of volumes will explode from about 800 (current # of 3590 primary
tapes) to thousands.

How about keeping the staging space so clients backup to staging then migrate
to FILE volumes.  Then every volume will be filled up.
