For Windows Server 2008, NetWorker uses the VSS Framework to backup
DFS-R. The DFS-R VSS Writer is backed up as part of a Windows system
state backup, and this backup includes DFS-R replicated folders. Since
the backup is part of system state, there are no capabilities to recover
individual folders or files.
The upcoming NW 7.5SP2 release will exclude Windows Server 2008 (and R2)
DFS-R replicated folders from system state backups allowing them to be
backed up as file systems. This will allow the ability to complete
granular folder and file recoveries. Release is planned for late Q1.

7.4.4, DFS backups work, but you only get the ability to recover the
entire DFS volume, not individual items within that volume.

initially, to the point where we had a case open with EMC on this issue
for several months before it was resolved. We did get it to work, but it
was entirely trial and error on the client side, with help from EMC.
What problem exactly are you having?
The problem I had was entirely different. What happened in my case was
that the backup would either crash immediately or at some point before
it should have ended normally, but it never hung. In my experience, hung
backups can often occur on Windows servers due to a firewall issue, so
if you haven't looked into that yet, I suggest you do so. Can you do a
regular backup (i.e., just back up C:\ and the VSS stuff) on that
client?
