Event ID 1584 — Cluster Shared Volume Backup

Applies To: Windows Server 2008 R2

Because of the design of Cluster Shared Volumes, backup applications for these volumes must meet specific requirements for compatibility. The Cluster Shared Volumes feature allows volumes in cluster storage to be accessed by all nodes of a failover cluster. This makes it possible for virtual machines to use volumes on the same LUN (disk) while still being able to fail over (or move from node to node) independently of one another.

Event Details

Product: Windows Operating System
ID: 1584
Source: Microsoft-Windows-FailoverClustering
Version: 6.1
Message: A backup application initiated a VSS snapshot on Cluster Shared Volume '%1' ('%3') without properly preparing the volume for snapshot. This snapshot may be invalid and the backup may not be usable for restore operations. Please contact your backup application vendor to verify compatibility with Cluster Shared Volumes.


Confirm Backup Compatibility with CSV

There appears to be a problem with the way that a backup application is performing a backup on Cluster Shared Volumes (CSV). Review the following:

  • Confirm with your backup solution vendor that the backup application is designed to be compatible with Cluster Shared Volumes.
  • Review any instructions the vendor provides for using their backup application.
  • Review the System and Application event logs, and any specific event logs for the backup application, looking for any errors that may be related to CSV or the backup application.


Confirm that the backup application can back up and restore Cluster Shared Volumes correctly. After backing up and restoring, check the System and Application event logs, and any specific event logs for the backup application, confirming that there are no errors related to backing up and restoring Cluster Shared Volumes.
