VSS SQL Writer

Question

Hello,

Support team, when we run our server backup in Veeam Replication software it completes with warning massage it shows SQL VSS writer is missing: database will be backed up in crash-friendly state and transaction log processing will be skipped.

Hi IT Support - RS Nagpal,

Thank you for posting in the Microsoft Community Forums.

Open Windows Service Manager and check the status of the “SQL Server VSS Writer” service. Make sure that the service is started and set to start automatically.

If the service is not running, try to start it manually. If the service fails to start, check the relevant error logs in the Event Viewer for more information.

Re-register the SQL VSS writer:

If the status of the service is normal but the problem persists, try re-registering the SQL VSS writer. This usually involves executing specific commands or scripts, and the exact steps may vary depending on the version of SQL Server and the installation path.

Check the SQL Server instances:

Ensure that all relevant SQL Server instances are running and that you are not experiencing any issues that prevent them from communicating with the VSS writer.

Check Veeam's configuration:

Check the configuration settings of Veeam to ensure that it has been properly configured for integration with SQL Server. This may include specifying the correct SQL Server instance, database, and backup options.

View event logs:

Review the application logs and system logs in the Windows Event Viewer for any error or warning messages related to the SQL VSS writer or Veeam backups. This information may help diagnose the root cause of the problem.
