That's yet another complication for us if were to use twins. We use
9840 (STK high capacity) tapes for our local backups and 3490 (in a VTS)
for our remote backups. We'd have to change our local backups to 3490
tapes, and we don't have enough silo slots to do that. A full backup
for us is 6 9840 tapes, or 145 virtual tapes. I tested a small backup
of 11 3390-3 volumes with twins. It took seven 3490E cartridges, and
seven 9840 cartridges. Mark is right, both streams get a new tape when
the first one hits EOT, even if they have vastly different capacities.
