Backup Exec 2014 - Differential backup running as a full backup

mattpwyman

We backup a Windows 2012 cluster using Backup exec 2014 sp2 which runs on a Windows  2012 server and had run fine for about 6 months. Recently the differential backups have started doing a full backup instead of a Diff.

I have tried rebuilding the backup job, using archive bit instead of modified time and reinstalling backup exec but with no luck.  The Full backup runs on a friday and runs over the weekend and we do Diff backups from Monday to Thursday.

I need this problem fixed pretty quickly as with no diffs I am relying on Weekly Full backups and hoping no ones deletes data in the week!

If you are doing AV scanning on the cluster, turn it off.

Any other backup (outside of BE) running ?

Thanks for the replys, we do not have any AV on the cluster and we have no other backup running.  I am completely stumped by this, nothing on the cluster has changed at all.

Does the Diff run as a Full ir-respective of choosing archive bit or modified time ?

If yes, pls log a formal support case. Thanks.

Yes it does - tried both archive bit and modified time.  Yesterday I applied all available patches to see that would make a difference but its still not working properly.  I logged a call with support a few nights ago and a engineer had a look but to be honest wasn't much help.
