I have 4 jobs (and 4 drives in a Powervault) running every night, and combined
they take 6 tapes. However there is enough capacity on 4 tapes to do the
job. Does anyone know how to force a job to append to a tape that was just
used by another job during the same night? When I removed the append protection,
it used another tape (count=7). I want to have all data on 4 tapes, and I
want to have at least 3 of the 4 drives running at the same time to reduce
the overall time required.
