The Online Restore Wizard provides reports that allow you to track changes of Active Directory (AD) objects by comparing the state of objects in backup and in a live AD LDS (ADAM) instance. You can also compare AD LDS (ADAM) objects held in two backups.
You can generate and view a detailed report about a particular compare or restore operation performed on AD LDS (ADAM) objects with Recovery Manager for Active Directory. Alternatively, you can generate and view a summary of all compare and restore operations performed with Recovery Manager for Active Directory on AD and AD LDS (ADAM) objects. Performing a compare operation on an AD or AD LDS (ADAM) object does not modify that object in any way.
To generate and view a report on AD LDS (ADAM) objects
To view a summary report about all compare and restore operations that Recovery Manager for Active Directory performed on AD and AD LDS (ADAM) objects, click the View Summary Report button at the bottom of the report window.
The Group Policy Restore Wizard helps you generate comparison reports that allow you to track changes of Group Policy objects by comparing their state in a backup and in Active Directory.
To generate and view a report on Group Policy objects
Note that the GPO comparison reports in the Group Policy Restore Wizard do not support providing information about certain Group Policy settings. For a list of unsupported Group Policy settings, see Quest Knowledge Base Article 12024 “Information on Some Group Policy Settings May Be Missing from the Group Policy Object Comparison Report” at support.quest.com.
You can use the Recovery Manager for Active Directory reports to find out which user modified specific Active Directory objects. To provide this functionality, Recovery Manager for Active Directory requires another Quest product - Change Auditor for Active Directory. Change Auditor is designed to collect information on all critical changes occurred in Active Directory and track user and administrator activity. For more information about Change Auditor for Active Directory, please visit http:/quest.com/products/changeauditor-for-activedirectory.
To provide information on who modified particular Active Directory objects, Recovery Manager for Active Directory integrates with Change Auditor and includes the data Change Auditor provides into the reports. In order to integrate, Recovery Manager for Active Directory and Change Auditor must be installed in the same Active Directory forest.
For a list of the Change Auditor for Active Directory versions with which Recovery Manager for Active Directory can integrate to provide information about the users that modified specific AD objects, see the Release Notes for this version of Recovery Manager for Active Directory.

Important: It is currently not possible to use the Repair Wizard to bring up a Domain Controller on identical hardware using a backup from a DC which is offline due to hardware failure. Despite being on identical hardware the operating system will contain many unique parameters. Those parameters are defined during the installation of the Operating System. Repair wizard will replace the current DIT file (with transaction logs) and the registry, however replacing the registry taken from another OS (even with similar hardware) may lead to OS instability or it may not function at all. For this reason, we do not recommend using the Repair Wizard in this situation.
To perform a complete offline restore
The Repair Wizard enables the recovery of the whole Active Directory database on a domain controller by applying a backup that was created for that domain controller.
You can use the complete offline restore to restore the entire Active Directory database from backup media without reinstalling the operating system or reconfiguring the domain controller. The restore can be performed on any domain controller that can be accessed remotely. By default, this operation restores all directory objects on the target domain controller non-authoritatively. This means that the restored data is then updated via normal replication. A non-authoritative restore is typically used to restore a domain controller that has completely failed due to hardware or software problems.
Important: A backup created for a given domain controller cannot be used to restore the Active Directory database to other domain controllers.
A complete offline restore also allows you to mark individual objects for authoritative restore. However, given that the granular online restore process provides the same functionality with much less effort and overhead, it is the recommended method for restoring individual objects to Active Directory.
During the final stage of a complete offline restore, the recovered domain controller is restarted in normal operational mode. Then, Active Directory replication updates the domain controller with all changes not overridden by the authoritative restore. It is important to note that until the replication update has completed, some of the directory object data held on the recovered domain controller may be obsolete. Therefore, execution of a complete offline restore may result in additional downtime due to replication delays.
There is one other consideration to make when performing a complete offline restore. Since you cannot use the backup from the other domain controller for the restore, the restored domain controller may lose information about the directory updates that were made after it was backed up. For example, suppose that some directory objects were added or modified on the domain controller after the backup was created, but the new objects or modifications were not yet replicated to other domain controllers. In this case, when the domain controller is restored, the new objects or modifications will be lost, because they were never replicated to other domain controllers, and therefore cannot be applied to the restored domain controller.
