I have a Netware 6.5 SP7 server with an HP Storage Works Ultrium 920 tape drive...it's a 400/800 gig drive so it should hold 400 gig in our system as our volumes are set with Compression ON. In the Tape Server screen on the Console Compression is set to OFF. Our backups are only saving about 90 gig on the tape before we get a Media Full message. I have had HP replace the drive twice and this has not resolved the issue. I'm at a loss as to why we can't get 400 gig on a tape. We have had this drive for about 4 months and have 270 gig total to backup. I believe I have gotten 270 gig on a tape maybe 2 or 3 times...and I didn't do anything different...it just worked. So, if anyone has any ideas or has run into this before I would love to hear resolutions. I think it's an Arcserve issue but their support is terrible...HELP....
