I suddenly started having problems with Windows backup. It was working fine for months and nothing has been changed and I've started to get this error within the Windows backup it says that the shared protection point timed out. In the windows event log I get the message:
The backup has failed because the Volume Shadow Copy service operation to create a shadow copy of the volumes being backup up failed with error code '2155348001'. Please help if anybody has the answer to this issue. I've had a look on microsoft but not found the answer.
