The Microsoft Exchange Replication Service VSS writer failed when aborting a backup.


This Error event indicates that the writer of the Volume Shadow Copy Service (VSS) of the Microsoft® Exchange Replication Service did not exit the ongoing backup process when the VSS writer received a request to stop the backup. The VSS writer might not exit a backup process as requested because it did not recognize the backup set.

User Action

To resolve the error, do one or both of the following:

  • Run VSS backup again on the storage group on which backup was stopped. If the successive VSS backups fail with a backup-in-progress error, stop and restart the following services from the Services snap-in. This will clear the backup-in-progress state for the storage groups that are affected by this failure:

    • Microsoft® Exchange Information Store service.

    • Microsoft Exchange Replication Service.

  • If you are using cluster continuous replication (CCR), stop the backup process that is running, restart the passive node of the cluster, and then try the backup again.
