Access denied V-79-57344-33928 when backing up Server 2012 R2 Active Directory with GRT

This issue has been solved. See solution.


I am unable to backup Active Directory with GRT enabled after upgrading AD servers to Windows Server 2012 R2. GRT backups of AD worked fine when the servers were at 2008 R2.


- the server being backed up is running Windows Server 2012 R2 with Backup Exec agent 14.0.1798.1364 (2012 SP4 agent)

- the Backup Exec server is Backup Exec 2012 with SP4 installed

The following error occurs when backing up System State on the AD server:


GRT backup set folder: D:\BEData\IMG000921
The consistency check of the snapshot for the Microsoft Active Directory, Active Directory Application Mode (ADAM) or Active Directory Lightweight Directory Services (AD LDS) database and transaction logs ntds was successful.
V-79-57344-33928 - Access Denied. Cannot backup directory  and its subdirectories.
V-79-10000-13307 - You have backed up a Windows Server 2012 computer. You cannot use the Simplified Disaster Recovery disk to restore Windows Server 2012 computers. However, you can run a manual complete online restore for disaster recovery or a physical to virtual conversion.


Backed up 27 System State components

1 item was skipped.


By experimenting with different backup options, I found when just the GRT option is turned off just for the Active Directory backup, the System State backup works fine. So, the problem seems specifically with trying to do a GRT backup of Active Directory system state information on Server 2012 R2.

The advanced option file option is enabled and set to automatic, and all VSS writers on the AD server report a healthy state when checking "vssadmin list writers".

Has anyone else encountered this?

You're probably getting this because BE 2012 (and BE 2010 R3 for that matter) do not support Windows Server 2012 yet. This is coming when BE 2014 is released. Here are details on what's happening in the Beta for this.

Until such time you're running an unsupported version of Windows unfortunately.

Thanks to both of you. I had misinterpreted statements about Windows Server 2012 support on the agent side to be for the R2 release as well.

Glad to have helped Tim!

BE 2012 supports Server 2012, but not Server 2012 R2.  As previously advised, you got to wait till BE 2014 for support.
