The quick answer is to turn off client software compression. But this
depends on other factors which you can find in the list archives at

Subject: Question about compression
We have 2 3580 drives with the 3583 changer. The devclass for these
drives shows them being of format=ultriumc, which I assume means
compressed. I have compression turned on at the clients. Are my drives
also compressing, or is there more to setting up drive compression than
formatting with the ultriumc option? When my tapes are first checked in
they show estimated capacity of about 200GB, once they are used and
"full" they show an estimated capacity of about 100GB.
Also, is there a "best" way to compress, or does it differ depending on
disk space, processor, backup window, etc.
Thanks in advance,
Jeff
