We abandoned butc a while back adn started doing disk2disk2tape using 
cheap ATA disks and raid controlers as the middle "disk" in the 
equation.  We use a home grown utility to do rotating incremental 
backups (basically uses vos dump) , then use veritas netbackup to get 
the stuff on tape.   Its completely automated.
