Well -- I get a compression ratio of 1.26 from backint on a 554 GB Oracle
database, and then manage to get around 102 GB per tape on Quantum DLT-7000
drives on the 35/70 GB tapes. So the Quantum drives, at least, are getting
about a 3:1 compression *after* the 25% compression from backint.

I'm not sure what you'll see on the 3590 drives, but it should be somewhere
in the same area.
