Getting started with Active Directory recovery

This section provides important information about performing data recovery operations with Recovery Manager for Active Directory. Please read it carefully before you start using the product to restore Active Directory data.

This section covers:

 

Active Directory recovery options

Recovery Manager for Active Directory enables the fast recovery of Active Directory from a disaster. The flowchart below indicates the most suitable recovery method depending on the type of disaster, which could be data corruption, database corruption, or complete Active Directory corruption.

Data corruption occurs when directory objects have been inadvertently deleted or modified, and the deletion or modification has replicated to other domain controllers within the environment.

Database corruption refers to a situation in which an Active Directory failure prevents a domain controller from starting in normal mode, or a hardware problem such as hard disk corruption on a domain controller.

Corruption of Active Directory forest can occur due to the Active Directory environment has been attacked by ransomware, or all domain controllers in the forest have been physically destroyed, etc.

Figure: Active Directory Recovery Options

Recovery Manager for Active Directory offers the following recovery methods:

  • Granular online restore

  • Complete offline restore

  • RMADFE recovery methods

  • Restore on Clean OS (available only in Disaster Recovery Edition)

  • Bare metal recovery (available only in Disaster Recovery Edition)

Granular online restore allows you to restore individual directory objects from a backup, without restarting the target domain controller or affecting other directory objects. It will not be necessary to shut down the domain controller in order to perform the restore: it remains online and functional throughout the recovery.

Complete offline restore only allows you to restore the entire Active Directory database on a domain controller while Active Directory is offline. To take Active Directory offline, Recovery Manager for Active Directory restarts the domain controller in Directory Services Restore Mode (DSRM), resulting in a period of downtime. In addition, complete offline restore affects all directory objects on the target domain controller, which may result in the loss of some of the most recent updates.

Recovery Manager for Active Directory Forest Edition recovery methods can be used to restore an Active Directory forest to the latest state from backups or reinstall Active Directory on selected domain controllers.

The Restore on Clean OS recovery method lets you restore a domain controller configuration from backup on a clean Windows machine. This option is available only in Disaster Recovery Edition.

The RMAD Bare Metal Recovery method restores the entire operating system with its configuration, including Active Directory and registry data (optional), in the case of non-bootable domain controllers or any other Active Directory failure. This option is available only in Disaster Recovery Edition.

All restore operations are remotely administered, so there is no need for an administrator to be physically present at the domain controller.

Granular online restore

To achieve near-zero downtime when recovering Active Directory, Recovery Manager for Active Directory provides the granular online restore method. Two options are available with this method:

  • Compare, restore, and report changes in Active Directory. With this option, you can restore particular objects from a backup, and select the necessary objects based on a per-attribute comparison of the objects in a backup with those in Active Directory. Comparison reports are also available.

  • Compare two backups and report differences. With this option, you can make a per-attribute comparison of the objects in two Active Directory backups. Comparison reports allow you to view the object modifications made in the period between the backups.

For details, see Using granular online restore.

Undeleting (reanimating) objects

With Recovery Manager for Active Directory, you can selectively recover deleted Active Directory objects by undeleting (reanimating) them. To undelete (reanimate) an object, Recovery Manager for Active Directory fully relies on the functionality provided by Active Directory, therefore to use this method you need no Active Directory backups. Note that you can only undelete objects in an Active Directory forest whose functional level is higher than Windows 2000.

For more information, refer Managing deleted or recycled objects.

Complete offline restore

You can use 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.

For details, see Using complete offline restore.

Recovery Manager for Active Directory Forest Edition recovery methods

Recovery Manager for Active Directory Forest Edition provides a number of Active Directory recovery methods that can be used to restore an Active Directory forest in case of different types of failures. For details, see Recovery methods

Restore on Clean OS

The Restore Active Directory on Clean OS method allows you to restore the entire forest or any of its parts on the freshly installed Windows machines. For example, when existing BMR backups contain the infected OS image, clean Active Directory backups can be used for the restore process.

For details, see Restore Active Directory on Clean OS recovery method.

Bare metal recovery

With the bare metal recovery option, you can restore the Active Directory components of the entire Active Directory forest after disaster situation when the recovered domain controllers do not have any pre-installed operating system.

The recovery process follows Microsoft best practices by using the following recovery methods:

  • Recovery from BMR backup (Bare Metal Restore)

  • Restore Active Directory and Registry data from Active Directory backup to bring Active Directory to the latest state

For details, see Bare metal forest recovery.
