Cluster Handling

If your Enterprise contains clusters, you can choose whether to restore the cluster quorums as part of the Windows 2000+ System State restore.

Do Not Restore Cluster Quorum	DPX does not restore the cluster quorum. Do Not Restore Cluster Quorum is the default.
Restore Cluster Quorum	DPX restores the cluster quorum. However, if other cluster nodes are active or if the cluster quorum has changed since backup, the cluster quorum restore may terminate.
Restore Cluster Quorum (Force the Recovery)	DPX restores the cluster quorum even if other cluster nodes are active or if the cluster quorum has changed since backup. Any changes made to the cluster quorum after the backup will be lost.
