We have a media agent that is failing to backup the DDB because the VSS snapshot could not be created
We have rebooted the server
The VSS list writers and list providers have no errors
vssadmin list writers
vssadmin list providers
The C drive is not full
Question: Are there any other items I can look at as a possible solution.
