We have been seeing this problem on several DomainControllers these past few days.

Processing SERVER Error: Unfreeze error (over VIX): [Backup job failed. Cannot create a shadow copy of the volumes containing writer's data. A VSS critical writer has failed. Writer name: [SqlServerWriter]. Class ID: [{a65faa63-5ea8-4ebc-9dbd-a0c4db26912a}]. Instance ID: [{47c33f5f-6b5c-4aa1-85a5-8caa7916000b}]. Writer's state: [VSS_WS_FAILED_AT_PREPARE_SNAPSHOT]. Error code: [0x800423f4].]

Was working with no problem a few weeks ago but one after another we see this problem.
If i reboot the machine the job can run once but second this i get that error.

Anyone else seeing this? Feels like a windows update thing.

Hi Danne84,

Could you please create a support case and post the support case ID here (and the follow-up after that)

What version of OS are we talking about?

Mike
