My customer encountered the same error twice already. Everything appears to backup and verify ok; however it is disturbing to see that the job failed in the job history. there must be some explanation as to why this happens.
My environment:
Windows Server 2000 - SP4 with the latest critical updates as of 5/11/05. Server is also an AD W2K Domain Controller. Exchange server 2000 - SP3, Symantec Corp Edition 9.0 Server, Symantec Mail Security 4.5 for Exchange, Veritas 10.0 5484 w/ SP1 and Hotfix 16. Compaq ML350 server w SCSI Tape drive - HP DLTVS80, 1.5 GB of RAM. Select Veritas, Exchange, Symantec directories have been excluded from the Realtime AV scan.
