Check the help to see if it supports compression on the drive. I doubt it.

You should see if the Tape manufacturer has any utilities to permanently turn on compression.

[ih  I hope this helps !

Commented:
Even if a tape drive supports compression, there are various reasons why you'll never get the 2:1 compression you would like.
See the bottom part of article http://seer.entsupport.symantec.com/docs/199542.htm for reasons why compression will be lower than 2:1.
