We are using a similar backup scheme to TSM, and we're forced to use old
AIX backup servers since the TSM API hasn't been ported to

I'm in the early stages of redesigning the backup system.  We have SAN
attached disk available, and my plan is to do a butc backup to the SAN
disk, and use that as my primary means of restore.  The incremental
scheme will last about 13-14 weeks, a semester's worth.  That directory
structure will then be sent to the TSM tape library, and we'll move back
to level 0 for butc.

I think this setup will give us speed and security.  I'd appreciate your
thoughts on this.
