I see two problems:

1) You can't compress the output from find and pipe that into cpio.  Try:
      find . -print | compress | cpio -oac > /dev/rmt0

   Note that since cpio isn't writing directly to the tape device, the
   "-B" option doesn't do anything.

2) If you get a bad spot on the tape later you won't (never say never :-)
   be able to recover anything beyond the bad spot.  This is a tradeoff
   when you use compress.
