Good afternoon, we are running an environment where we have an E4500 master and 
2 V490 media servers.  We are using an L700 and LTO drives.  All fiber attached 
via Brocade switch.  Every morning we run a differential catalog backup that 
goes offsite with tapes.  In the early afternoon we run a full catalog backup.  
For some reason every Thursday morning the catalog backup diff runs as long as 
a full and backs up as much data as a full.  Every other morning the diff runs 
in 5 minutes.  I've looked at the amount of data we are backing up Wednesday 
night and its not different than any other night (2.5TB).   

Has anyone else seen this happen?

Thanks!

Tim
