VSS Writers Names and Services That Go With It – KB10392284


Description:  This will give you the list of the common writers you will see and the services that go with it to restart

Steps to resolve:

This can be used for any backup that might have an issue with writers

1. Run the Command Prompt as an Administrator

2. Type vssadmin list writers. This will populate a list of the writers.


3. To find if a writer is having an issue, look at the state, it will say Failed and the reason for it

Failed Writer

4. Usually, you would have to reboot the server to “reset” the writers but there is an easier way to do that. Instead of rebooting the server, try yo restart the service that corresponds with the writer.

Here is the list:

*Not all the writers will be covered in this list*

Additional considerations: If this does not correct the issue, then a reboot of the server would be necessary, contact the customer and see when it would be convenient for them to reboot the server. Remind them that their backups will not work until the server gets rebooted to reset the writers.
