Hi. I am running Backup Exec v8.6 for Windows 2000 Server. I have the entire C: drive and System State selected for back up. Also I have Exchange 2000 on the server and am trying to back up mailboxes and information store as well (w/ Exchange agent installed). My issue is at 99% done with the verify process the back up says "Failed" "Unknown Reason" When I look at the log all I see is that it skipped over a few open files and one valid user's information store on Exchange. However, I run it to "Never" back up open files. I have a HP DLT 40/80 GB tape drive and a Dell PowerEdge 1400SC server. Can someone help me out with this issue? Can someone point out what I am doing wrong? Thanks.
