Recovering Group Policy

Recovery Manager for Active Directory (RMAD) enables the recovery of Group Policy data from corruption or inadvertent modification, which can be caused by either hardware failure or human error.

Figure: Group Policy Recovery

If specific Group Policy objects or links are inadvertently deleted or modified, they can be restored from a backup of a domain controller’s Active Directory® components, without restoring the entire Active Directory®, restarting the domain controller, or affecting other objects.

Recovery Manager for Active Directory includes the following options for Group Policy recovery:

  • Policy settings restore. If the Group Policy object was modified since the backup was created, this option restores all policy settings to the state they were in at the time of the backup. If the Group Policy object was deleted, this option creates a new object with the same name and policy settings as the backed-up object.

  • Security settings restore. Restores all security information contained in the Group Policy object. As a result, all users and security groups receive the access permissions that were specified in the Group Policy object at the time it was backed up.

  • GPO links restore. Restores all links associated with the Group Policy object to the state they were in at the time the backup was created. As a result, the object is once again used by the same sites, domains, and organizational units that were linked to it at the time the backup was created.

  • Comparison reports. Shows whether Group Policy object was deleted or modified since the backup time.

You can use any combination of these options. For example, suppose some links to a Group Policy object are accidentally deleted. If your backup contains an outdated version of the Group Policy object, you can restore only the links, without restoring the policy settings or security settings.

Group Policy restore

To eliminate downtime when recovering Group Policy, RMAD provides the Group Policy Restore method. This method allows individual Group Policy objects to be restored to a selected domain controller. The operation can be performed on any domain controller that can be accessed remotely. Using this method, domain controllers do not need to be restarted, and only those objects selected for recovery are affected.

For this type of restore, it is not necessary to create any special backups; you may use any regular backup of domain controller’s Active Directory® components.

A Group Policy Restore is particularly helpful when critical Group Policy objects or links have been inadvertently deleted or changed. To recover from such situations, you may carry out a Group Policy Restore to a domain controller using a Active Directory® backup that was created before the objects in question were deleted or modified.

Group Policy Restore allows you to roll back changes made to Group Policy information, and return individual Group Policy objects to the state they were in when the backup was created. It is important to note that a Group Policy Restore only affects the object selected for recovery, and optionally, the links to that object. Any objects that are not involved in the operation remain unchanged in the domain.

 

Comparison reports

Recovery Manager for Active Directory (RMAD) 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.

RMAD 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.
