An Automated System Recovery backup of the system state fails on a Windows Server 2008 failover cluster node if the database of an application is saved on a shared disk

Consider the following scenario:
  • You have the Failover Clustering feature installed on a computer that is running Windows Server 2008 or Windows Server 2008 Service Pack 2 (SP2).
  • You install an application on this failover cluster node. The database of the application is saved on a shared disk.
  • You try to perform an Automated System Recovery backup of the system state by using the Wbadmin.exe command-line tool on the computer.

    Note There is no option to retrieve only the system state backup from the Windows Server Backup management console on Windows Server 2008. Therefore, run the wbadmin command to back up only the system state. To do this, open a command prompt by using an administrator account, type the following command, and then press Enter:
    wbadmin.exe start systemstatebackup -backuptarget:letterdrive
In this scenario, the backup fails. Additionally, the following error message is logged in the Application log:

Log Name: Application
Source: SPP
Date: Date
Event ID: 16387
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: Computer Name

Shadow copy creation failed because of error reported by ASR Writer. More info: Automated System Recovery failed the shadow copy, because a selected critical volume is located on a cluster shared disk. This is an unsupported configuration. (0x80042405).

For example, this problem occurs if you install one of the following services on a Windows Server 2008 failover cluster node and the databases for the service are saved on a shared disk:
  • Windows Internet Name Service (WINS)
  • Dynamic Host Configuration Protocol (DHCP) Server service
  • Certification authority (CA) role service
This problem occurs because the Automated System Recovery writer in Windows Server 2008 disallows a backup on the shared disks when the shared disks are marked as critical.
To resolve this issue, you must apply this hotfix and create a ClusteredCAEnabled registry key. For more information about how to create a ClusteredCAEnabled registry key, see the "Registry information" section.

Note Windows Server 2008 does not support Bare Metal Recovery backup for cluster shared disks that are marked as critical volumes, even after you install this hotfix. Bare Metal Recovery backup is supported by Windows Server 2008 R2.
