Backup Exec 2012 Incremental Backups Very Big
I have been trying to resolve this issue myself for a few days now but not getting anywhere at all. Basically, my incremental backup jobs are far too large and despite going through my settings with a fine tooth comb I cannot understand why this is happening.
To give a brief overview of my set-up - Backup Exec 2012 Capacity Edition running on Windows Server 2008. All of my servers to be backed up are Windows 2003 or Windows 2008 - no VM's or Exchange DAG's to muddy the waters until I'm happy with the current set-up.
I have my rotation set to retain data for 1 week - 10 LTO4 tapes in total.
Mon - Thurs jobs are incremental
Friday jobs are full.
I had a backup job running last night - it was incremental and backed up over 160GB from a server which has a total capacity of 180GB. There is **no way** this much data changed over night. It's a simple file server and the incremental jobs used to backup around 4GB of data per night.
The backup job finished at 17:30 with 160GB in total backed up. I have just run the same job again this afternoon and already it is approaching 145GB with some way to go until completion.
What I'd expect to see is the full backup on Friday taking all 180GB's followed by 4 incremental daily jobs taking around 4-10GB per night.
The backup selection is using the modified time and the BERAW agent is installed - latest service pack installed.
Please can someone advise what steps I can take to resolve this issue?
