The backup command MAY be doing what you wish.  

Look at the restore command.  When the tape is written with /dev/rmt0.1,
then you MUST use the -s flag with the 'restore' command.  For example,
"restore -i -s 1 -f /dev/rmt0.1" will read the first backup file on the
tape.  Note that it is the device name when writing the file that is
important, not when reading.

If you just do "restore -i -f /dev/rmt0.1" it will read the *SECOND* backup
file on the tape!!!

I really got bit by that one when we were setting up our backup program.
