arcserve-KB : How to manually restart VSS Writers in a failed state without Rebooting Server.

Last Update: 2017-08-03 18:17:38 UTC

Description:

There are instances when snapshots are fail 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.

Solution:

An alternative solution other than restarting the server is to restart  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 using the command in command prompt (Run As Administrator)  - ' vssadmin list writers '.
  • Mark and copy all the failed VSS writers.
  • Find the VSS writer's associated Service Display Name in the table below and restart the service.
  • To confirm the status has changed Stable with no Error - type - vssadmin list writers

  • Run another Backup/snapshot.
  • If the VSS writers fail again, it would be necessary to restart the server.
