We use Azure to backup some of our servers. We had 2 servers backing up successfully and tonight had to switch the Azure account they were backing up to - pretty straight forward.
Now the backup services are re-linked; one server is working totally fine and the other is presenting issues.
The backup service fails with a generic error, doing a little digging I was advised to run (Inside Diskshadow):
SET CONTEXT VOLATILE NOWRITERS
SET METADATA C:\Metadata.cab
SET VERBOSE ON
ADD VOLUME C: ALIAS systemVolumeShadow
BEGIN BACKUP
CREATE
END BACKUP
EXIT
This fails with the following error
Returned HRESULT: 80042306
Error Text: VSS_E_PROVIDER_VETO
Looking in the Event Logs I see this
The shadow copies of volume c: were aborted because of a failed free space computation.

Any suggestions?

The machine has around 80gig of spare space.
All the Writers show Stable and No Error.
