Restoring Data › System State Restore Options

System State Restore Options

Right-click the system state session to access the restore option context menu. The following options are available:

• Make the Restored Copy of the Active Directory Authoritative--Forces the restored copy to become the "authoritative" version of Active Directory on the system. This means that, even if the restored replica set is older than the current replicas, the older data is replicated to all of its replication partners. Authoritative restore is typically used to restore a system to a previously known state.

  Note: Windows Server 2008 systems do not support placing the Active Directory in an authoritative mode.

• When Restoring replicated data sets, mark the data as primary for all replicas--Forces the restored File Replication service data to be replicated to other servers. If this option is not enabled, the replicated data sets may not be replicated to other servers because the restored data will appear to be older than the data on other servers.
• Stop the Cluster if necessary to Restore the Cluster Database--Gives permission to stop a cluster service to restore the cluster database. This applies only to cluster machines. If this option is not enabled and the cluster service is running, CA ARCserve Backup dumps the cluster database files into the%SYSTEMROOT%\clusbkup folder, but does not load them. CA ARCserve Backup provides a utility program (caclurst.exe) that lets you load the cluster database files at a convenient time.
• Enable Quorum Drive Selection when Quorum Location Changes (Non-Windows Server 2008 Cluster only)--Lets you to set the drive of the quorum resource that a cluster currently uses. If a cluster system was reconfigured to use a different quorum drive since the last system state backup, use this option to provide the new quorum drive. Otherwise, the backup copy of the quorum drive will be used which will cause the cluster database restore to fail.
  • Select the drive letter in the case the quorum location changed since this backup--Lets you specify a drive letter to restore data to when the location of the quorum changed since the backup was performed.
• Authoritative Restore Cluster Database (Windows Server 2008 Cluster only)--Lets you perform an authoritative restore on Windows Server 2008 clusters. An authoritative restore lets you to restore the cluster database across all nodes. You should enable this option when you want to roll back the cluster configuration to the previous version.

  Use the following guidelines to determine when to process an authoritative restore or a non-authoritative restore:

  • Authoritative restore--An authoritative restore lets you use the cluster configuration that is stored in the backup data, not the current cluster node configuration, to recover the node. An authoritative restore lets you allow the cluster to use the restored configuration as the most recent configuration. If you recover the node using an authoritative restore, the current cluster configuration replicates to all of the nodes in the cluster.
  • Non-authoritative restore--A non-authoritative restore lets you use the backup data to recover disabled nodes. With a non-authoritative restore, the latest cluster configuration information replicates to the recovered node after it becomes functional and joins the cluster.

  Be aware of the following behaviors and considerations:

  • The Authoritative Restore Cluster Database (Windows Server 2008 Cluster only) option can be applied at the node level.
  • If the node that you want to restore is corrupt or disabled, you must perform a node restore before you perform an authoritative restore. To perform a node restore, do not enable this option.
  • You must restart the node after you perform an authoritative or a non-authoritative restore.

  Note: For information about recovering clusters from a disaster, see "Recovering Clusters" in the Disaster Recovery Option Guide.

• Do not Stop World Wide Web Service--Lets you continue the www service while the certificate server is being restored. The IIS Publishing Service may be using the certificate service dynamic files at the time of certificate server restore. For this reason, by default, WWW service will be stopped during certificate server restore. If you do not want it to stop, use this option.
