Two things. You say your changer is /dev/sg3 but your conf file says sg2. Also, nowhere in the conf files is a tape device defined. As to using multiple drives, amanda is not designed to do that. Ways amanda users do use multiple drives include: chg-multi which treats two (or more) drives as if they were a tape changer with a single drive set up multiple configs, each backing up a different set of hosts. assign a separate group of slots and 1 drive to each config use the drives as a RAIT, either mirroring the data or striping the data across the two drives -- Jon H.
