You could create just one job, pointed at the library as a whole. then re-label/quick erase the tapes starting at slot 1, so that Backupexec will grab them in slot order. Make the Overwrite Protection Period of the media set 19 days.
Slightly more work would be to partition the library. With a seven slot autoloader create a slot for each day, then create seven jobs, each pointing to a specific slot. Veritas treats each partition as a Vitual Tape Drive, so Monday's job will only write to Monday's slot. Remember that you need to inventory all slots when you change magazines, so that Veritas know what tapes are now mounted.
