BackupExec 2014 - Client side dedup on DCs (Domain Controllers)
In my environment I backup physical servers using client side dedup option to reduce network usage on backup windows.
I noticed that backup of my DCs fails consistently after trying many different setting I found that when I use normal dedup (not client side) my backup jobs finished successfully.
I wonder, did anyone else have the same problem? or did anyone succeeded on backing up DCs using client side dedup?
Note: I tried backing up both 2008R2 and 2012 servers with DC role and I see the issue on both versions.
The error that I get when trying to backup using client side dedup is:
Job Completion Status Job ended: Monday, July 21, 2014 at 11:04:22 PM Completed status: Failed Final error: 0xe000fe30 - A communications failure has occurred.

V-79-57344-41488 - Due to one or more errors in \\DC_FQDN\System?State, this backup cannot be used for conversion to virtual machines, Simplified Disaster Recovery (SDR), or a complete online restore.
Hope this helps someone, if anyone have a different solution I would like to hear.
