Hi, im using arcserve 2k on a dell poweredge 2650 running windows 2000. I'm using a Spectra 2k which uses 2 Sony SDX-500C tape drives that support hardware compression.
I have read many if not all the topics related to this issue and i still can not get compression to work. I've checked the device and both tape drives show hardware compression on, i've also used a the testing software from specralogic to test the tape backup unit and it has compressed test data successfully.
I've attempted backing up the server locally, the raid attatched to the server, and a raid attatched to sun we also have running here. i get zero compression on all backups, i'm using 50/100 AIT2 tapes and once they get to exactly 50 a new take picks up.
This has been driving me up a wall for 2 weeks now, i can not get any compression and i know it was working before when the tape back up was attached to an older server running windows NT. I've tried everything listed in the Faq as far as compression is concerned the drive only supports hardware compression i can not turn it off to try using software compression.
I would appreciate any help i could get thank you.
