Hello,
We actually have an issue about backup.
We cannot backup our server.
Here the log from Event Viewer \ Application :
The backup operation that started at '2016-03-17T15:00:34.930000000Z' has failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '2147943484'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.

We uninstalled the Windows Server Backup feature and reinstalled it with no more success.
We rebooted the server in rescue mode and performed a reparation and we registered all VSS DLL. No more success.
Could you please help us.
