Recovery Manager for Active Directory enables the backup and restoration of the following System State components on Active Directory domain controllers:
To restore backed up System State components
To ensure the selected backup contains all System State components needed for the restore, browse the System State branch on the Computer and Backup Selection page.
With the Repair Wizard, you can restore data from System State backups created by applications that store backups in Microsoft Tape Format (MTF), such as Windows Backup or Veritas Backup Exec. To use a backup, on the Computer and Backup Selection page, click Register, and then click Register Backup File. The wizard catalogs the backup and adds a new entry to the list of backups.
Snapshot backups are not supported by the Repair Wizard. However, you can restore Active Directory data from such backups using the Online Restore Wizard and Group Policy Restore Wizard. The Extract Wizard also supports snapshot backups.
When restoring the Cluster Quorum component on a cluster node, Recovery Manager for Active Directory leaves the quorum data in a folder on the node's disk, but does not restore it to the quorum disk at that time. Restoring the quorum disk requires that the cluster be stopped and restarted, which may not be necessary or desirable.
The process of restoring a single node of a cluster is straightforward: you must restore all the System State components, including Cluster Quorum, to the node, and then restart the node. This causes the node to rejoin the cluster and restores it to operation.
To restore the quorum disk, following the node restore, use the Cluster Quorum Restore tool (Clusrest.exe) provided by Microsoft.
To restore a cluster node using Recovery Manager for Active Directory
When restoring a cluster node, you must use a backup taken from that particular node. Therefore, it is important that you select a backup of the node you are restoring. We recommend creating backups of cluster physical nodes (computers) rather than a cluster itself (cluster virtual node). Otherwise, it will be difficult to identify the physical node from which the backup was taken.
To restore the quorum disk with the Clusrest tool
This causes the quorum disk to be restored to the state of the backup.
If the quorum data to be restored to the quorum disk is not found, the Clusrest tool reports FILE NOT FOUND.
The restore of a cluster node must be performed prior to running the Clusrest tool. During the restore of a node, the quorum data is placed on the node's disk in the %windir%\cluster\cluster_backup folder.
If the restored system is not part of a cluster or the quorum disk is not available, not formatted, or broken, the Clusrest tool reports ERROR_SERVICE_DOES_NOT_EXIST.
To perform granular online restore
Note: Recovery Manager for Active Directory can also recover individual AD LDS (ADAM) objects. To restore AD LDS (ADAM) objects, use the Online Restore Wizard for AD LDS (ADAM).
Granular online restore should be used in situations where important object data has been inadvertently deleted or changed in Active Directory, and the changes have been propagated to other domain controllers. To recover from such an event, you can carry out a granular online restore to Active Directory using a backup that was created before the objects in question were deleted or modified.
Granular online restore is always authoritative: it restores Active Directory object data to the state the data had when the backup was created, and any updates that were made after that point are lost. After Recovery Manager for Active Directory completes a granular online restore on the target domain controller, the restored objects are replicated to the other domain controllers via the normal replication process. Given that the objects recovered by a granular online restore have a higher version number, recently deleted or modified object data is ignored during replication.
Granular online restore allows you to roll back changes made to Active Directory, and return individual directory objects and attributes to the state they were in when the backup was created. It is important to note that a granular online restore only affects the objects and attributes selected for recovery. All other objects remain unchanged in Active Directory. Furthermore, if the value of an attribute in Active Directory is identical to the value it has in the backup, the granular online restore does not attempt to change the attribute.
The wizard offers two options:
