Error E4F3000F: Unexpected VSS writer error. Check the application event log

Running VSR 2016 on Windows Server 2012R2. Backups ran for a week then started erroring out with the following: Error E4F3000F: Unexpected VSS writer error. Check the application event log
 for writer specific error. Failed VSS writers: System Writer

I see this problem with SSR 2013 listed in articles with a hotfix, but nowhere do I find anything on VSR 2016.

I see this problem with SSR 2013 listed in articles with a hotfix, but nowhere do I find anything on VSR 2016.

Generally speaking, any fix for a previous version will automatically be included in future releases. Without checking I cannot be sure, but the fix should already be in VSR 16.

When you see the issue, run VSSADMIN LIST WRITERS from a command prompt to confirm the status of all writers. Also run a test using DiskShadow (for this test, backup exact same volumes that you are backing up with VSR) and check the results: http://www.veritas.com/docs/000097851.
