media manager received no data for backup image (Status code 90) DFSR Backup

I've ready several tech notes and forum posts, but most of them talked about a backup selection being filtered by VSS and a backup of a direct path (E:\MyFiles for example) is protected by the Shadow Copy. becuase they are DFSR.  I'm getting the error when I try and backup the Shadow Copy path.  I've reqyested the bpbkap log from the client, I can post that when I have it.  In the mean time, here is what I have to start with.

Master RHEL 6 NBU 7.5.0.7

Client Windows 2008, NBU 7.5.0.6

Policy Backup Selction:

Shadow Copy Components:\User Data\Distributed File System Replication\DfsrReplicatedFolders                   (failes the full backup only)
D:\                                                                                                                                                                  (works with no issues)

File List:

SET SNAP_ID=ammfs02_1450054801
Shadow Copy Components:\User Data\Distributed File System Replication\DfsrReplicatedFolders

The Incremental backups don't fail, I suspect thats becuse there is nothing to backup and it does not care.  If I just do the default Shadow Copy Components, that works fine as well.  I've asked that the customer confirm that path is correct and valid and they indicate that it is.
