Webroot has received reports of symptoms similar to those that you have reported. As a temporary measure there are two options for alleviating this issue.

First:

If you are utilizing the Task Scheduler for the backups to be performed (This can be seen in the system-Scheduled_Tasks.csv or Task Scheduler in Windows).

Example : C:\Windows\system32\vssadmin.exe Create Shadow /AutoRetry=15 /For=\\?\Volume{f3eeccd1-6c54-43d9-b19e-6695945f7934}

This command can be replaced with the following instead : wmic shadowcopy call create Volume=c:\

(Volume letter depends on the corresponding volume id they are attempting to copy)

Second:
