Hello,

Our Networker server fails sometimes to backup its C:\ drive (is randomly; sometimes it happens twice a week and sometimes it doesn't happens in two months) with the error messages similar to these:

--- Unsuccessful Save Sets ---

* backup_server:C:\ 1 retry attempted
  backup_server: C:\        level=1,       444 MB 00:00:45    142 files

* <WARNING> : File C:\ could not be opened and was not backed up. (The specified network resource or device is no longer available.

Any idea about what can be the cause for these random VSS errors?

Thank you.

PS: Our server is W2K8 Standard SP2 / NetWorker 7.6 SP1
