Still confusion, you are not following the primary part of my comment.

On a real tape drive you specify the tape drive as something like

        /dev/nst0     or      /dev/rmt/0ln

You don't say the "fourth file on the tape drive".  Your "tape drive"
is file:/Backup  or  file:/Backup/DailySetX.  I'm not sure which, but
it certainly is NOT file:/Backup/DailySetX/anything
