Brandon, We've been running a 20 tape/2 drive changer for more than 3 years now and have a separate config for each of the drives. cron starts two jobs each night to backup about half of our workstations/servers to each tape drive. The daily jobs use about two tapes each and the weekend (full only) backups each use 6 tapes. This has been very successful for us. The only manual intervention required is balancing of systems in each disk list. These backups are for 242 filesystems and about 342 GB on about 60 workstations and servers.
