I am running Standard Server 2003 R2 with file server, DHCP Server and domain controller roles. Periodically, after a few successful (or reportedly successful) backups, the machine will go weeks on end failing backups. The configuration is:
Physical Drive 0 –
c: [OS partition]
e: [Data partition]
Physical Drive 1 –
c: [OS partition Mirror]
e: [Data partition Mirror]
Physical Drive 2 –
k: Partition for NT Backup
m: Partition for Clone.
Examining the logs, it appears that c: backs up with no errors. e: begins to backup, then, around the 4 GB point, e: is reported invalid and the backup fails.
Thinking there might be something wrong with NTBackup, I tried Backassist, Norton Ghost, and Acronis software. All failed in different ways. The drive is definitely alive because the users access it on a daily basis. Has anyone experienced this set of circumstances and solved this problem?
