SBS 2003 Backup recently failing on Exchange
I have a client running SBS 2003. Backups have worked fine for ages, but for the past couple of weeks have been failing on Exchange.
The error in the backup log is:-
I have run an integrity check on the stores, and they seem OK.
The backup runs to an NAS box. The NAS box has more than enough free space for this.
Everything else backs up OK, I just can't figure out why this fails.
The error in the backup log is:-
Backup of "MYSERVER\Microsoft Information Store\First Storage Group"
Backup set #3 on media #1

@davorin - yes I have seen that KB - this is a full backup that is scheduled to run daily. There are no incremental or differential backups, and circular logging is already enabled on Exchange.
The user account has ALWAYS had enough permissions, and backups were working up until a couple of weeks ago - however, there have been no changes to the user account, hardware etc to cause it to stop.
Finally there is more than enough free space on the target drive.

Re-creating the job from scratch after deleting all existing .bkf files from the backup location AND removing the configuration XML files data from the registry seem to have cured the problem.
