We are using ArcServeIT 6.6 on an NT platform for both LAN & WAN backups. Our tape drive is the 15/30 DLT. Each time that I backup one of our primary servers, (Friday full backup) it requires that I insert a second tape. And each time the backup fails and the job is cancelled. I've checked the setup, and all is set to overwrite. I've manually formated the tapes, named both tapes the same & even tried nameing them differently. The backup works fine until the second tape is inserted. Anyone have an idea as to what is wrong?
