Differential job backing up all files
I have a Windows 2008 R2 file server that is configured for a full backup with Backup Exec 2012 over the weekend and differential's during the week. The full ran for the first time last weekend and the first differential job started last night. The full completed successfully. However, the differential is also backing up all files just like a full. Any suggetions on why it is not only selecting the changed files since the full ran? The only reason I have come accross so far was if the full didn't complete successfully, which in my case it did.
Any help is appreciated.
