Recovery Manager for Active Directory Disaster Recovery Edition provides comparison reports to assist with isolating deletion or changes to Active Directory or AD LDS (ADAM), and troubleshooting the resulting problems. These reports are based on per-attribute comparisons of Active Directory, AD LDS (ADAM), or Group Policy objects selected from a backup, with their counterparts in Active Directory, AD LDS (ADAM), or another backup.
By comparing the state of the directory objects or Group Policy objects in Active Directory with those in a backup, comparison reports improve the efficiency of recovering objects, by allowing you to specify precisely which objects should be restored.
By showing the changes that would be made to Active Directory or AD LDS (ADAM) during a restore operation, comparison reports help to highlight possible side effects that could result from restoring data. If such side effects are indicated in the report, you may then reconsider whether to apply the changes to the “live” directory data.
Comparison reports may also be used to monitor changes that occurred in Active Directory or AD LDS (ADAM) since the backup was created, or within the period between two backups. Comparison reports assist with troubleshooting Active Directory, and resolving problems that may result from the deletion of critical objects in Active Directory. The reports also help you monitor changes made to Active Directory or AD LDS (ADAM) by third party applications.
The ability to compare the current state of objects in Active Directory or AD LDS (ADAM) with their state in a backup helps when troubleshooting problems that may result from the deletion or modification of a user account or an Organizational Unit, or modification of more critical objects. Comparison reports show whether critical objects were deleted or modified since a backup was made.
The deletion of critical objects such as a domain controller’s computer account or the "NTDS Settings" object is one of the most common causes of Active Directory problems.
Other critical, equally sensitive objects include all objects in the System container, such as FRS subscription objects, trusted domain objects (TDO), and DNS objects. By comparing the current state of objects in the System container with the state of the objects in a backup, it is possible to isolate problems that result from the absence or incorrect modification of critical objects.
Recovery Manager for Active Directory Disaster Recovery Edition serves as a valuable tool when implementing a change management process. The importance of testing changes to Active Directory is paramount, whether you are changing configurations, installing new software, or implementing service packs and patches. The product has the ability to report changes, and if necessary, roll back changes made to Active Directory. This improves the effectiveness of testing application deployment scenarios in a laboratory environment, and monitoring changes made to Active Directory by third-party applications.

Recovery Manager for Active Directory employs a Backup Agent to back up data on domain controllers and AD LDS (ADAM) hosts added to Computer Collections. For this reason, the Backup Agent must be installed on each computer where you plan to back up data by using Recovery Manager for Active Directory.
For each Computer Collection, you can specify whether you want to use only preinstalled instances of Backup Agent or want to automatically install Backup Agent when necessary. You can configure Recovery Manager for Active Directory in one of the following ways:
You can specify one of these methods in the Computer Collection properties. For more information, see Agent Settings tab subsection in Properties for an existing Computer Collection.
