The other major disadvantage of Disk device class to me is no multi session
restore.

Very interesting.

It sounds to me like an opportunity for Tivoli to create a white paper
for us TSM admins on "Best Practices in a Disk-Only TSM Environment".
Although I would really prefer that they come up with a solution for the
DISK fragmentation problem so  that I don't have to cludge around with
FILE types.  While they are at it, maybe an online database defrag
utility would come in useful as well...
