I checked teh event viewer log , and see the following -
Backup job 113 on UNKILOSERVER did not succeed. Reason: ClientVssInsufficientSpace, System.String
The drive on the client PC is a SSD drive. I believe it is NTFS (it is a relatively, less than 6 months old, new Win 7, 64 bit install).
Does that help? Thanks for your help…
