How to Manually Restart all VSS Writers when in a Failed State without Rebooting -
Description
There are instances when snapshots are failing due to an agent's VSS writers being in a failed state but it is impossible or not desirable to restart the server until at least after business hours. -
Cause
The VSS writers may be in a failed state for many different reasons. Once they are in a failed state, it is usually necessary to restart the server. -
Résolution
An alternative solution other than restarting the server is to restart each of the associated services for each of the VSS writers showing up in a failed state by following the steps below:
- Find each of the VSS writers in a failed state by issuing this command in an elevated command prompt - vssadmin list writers.
- Make a list of all the failed VSS writers or take a screenshot.
- Find the VSS writer's associated Service Display Name in the table below and restart the service.
- Issue the command again to confirm the status has changed Stable with no Error - vssadmin list writers.
- Attempt to perform another snapshot.
- If the VSS writers fail again, it will be necessary to restart the server.
Warning: Please beware that restarting the Microsoft Exchange Writer can cause disruption for users to connect to Exchange. It is preferable to schedule a reboot of the machine in this case during a planned downtime.
