I have a brand new Ultrium 920 tape drive and am using 400/800 gig tapes. File compression is on on our Netware volumes so I expected to get 400 gig on one tape. We have 260 gig total to backup...figured no problem...well I got in this morning and Arcserve was asking for a second tape...it had only backed up about 60 gig before asking for the second tape. These are brand new tapes. Any idea's? Not sure if this is a tape drive or tape issue, or if it is an Arcserve issue..i'm leaning towards Arcserve..i hate it..
