To cut a long story short, I had to re-setup a File Server in DPM. The server had been backing up fine before, but when I set up the protection again, the Synchronization Failed with
The replica of F:\ on
%servername% is inconsistent with the
protected data source. All protection activities for this data source will fail
until the replica is synchronized with consistency check.
DPM failed to synchronize changes for F:\ on %servername% because the snapshot volume did not have sufficient storage space to hold the churn on the protected computer.

I checked the disk space on the server - it has 7TB free!
I ran the usual VSSadmin commands, checked the VSS settings via the GUI, changed the sizes to unlimited etc.
The backup still failed with the same error.
As the server had been in production some time I had a thought...when the server was first set up, Quotas were not configured and they are now. So I turned off the Quotas and the backup worked!
