You cannot do this. You can backup both to the same drive
consecutively, obviously, but you have to change tapes in between.
You could use a no-rewind device and consecutively write the second
archive to the second file on the tape but ontape will not be able to
restore the second archive since it rewinds the tape twice during the
restore. You would have to manually copy the file off of the tape to
another device. Not fun and I've never tried this myself.
