I think the 172/320 should work the same as VXA-2. I have done some single
tape backups and restores with success but did not try btape with single
tapes. The multitape backup is the big issue. I am using bacula because BRU
would not work and BackupExec is not supported on this unit as it is
firewire.
I am preparing for a multitape real test with 30 1G files.
Thanks,
