Do nothing method

This recovery method does not perform any actions on the domain controller and does not remove it. This method is available only if the Repromotion recovery mode is selected on the Recovery Mode tab of Recovery Project Settings.

The Do nothing recovery method is set for all running domain controllers that were recovered during Phase 1 of phased recovery. For details, see Phased recovery.

 

Adjust to Active Directory changes method

This recovery method is available and selected automatically when the domain controller is a Global Catalog server and belongs to the excluded domain, and either Rebuild GC, advertise normally or Rebuild GC, advertise fast is checked on the Global Catalog tab of the project settings. You can suppress any of the first two options using advanced settings.

How the Adjust to Active Directory® changes method works:

  1. The agent removes lingering objects from other recovered domains, if any, using the Repadmin tool.

  2. If the previous step fails, the agent performs unhost and rehost of recovered domain partitions using the Repadmin tool.

  3. Only if both previous steps fails, the agent rebuilds Global Catalog on this domain without attempts to remove lingering objects. In case of full reset of Global Catalog, the replication of Global Catalog data may require additional time.

For details about recovery method settings, see Domain controller recovery settings and progress.

Phased recovery

Recovery Manager for Active Directory supports phased recovery of the Active Directory® forest. This scenario lets you perform the initial recovery during the first phase to make the forest function as soon as possible. The second phase can be postponed, so the full forest structure can be restored later.

  • Phase 1: Perform initial recovery
    Perform restore of one or several domain controllers in each domain.

  • Phase 2: Redeploy remaining DCs
    Restore remaining domain controllers using the Install Active Directory® recovery method.

Phase 1

Restore the selected domain controllers using any appropriate recovery method. For domain controllers that you do not plan to restore in this phase, use the Do not recover method with the enabled Keep this domain controller in the project option that allows you to remain the domain controller in the project and restore it later. If the Keep this domain controller in the project option is not checked, the domain controller will be permanently removed from the recovery project after the project update.

Resources/Images/do_not_recover_option.png

To update the project, click Tools | Update Project with Changes in Active Directory on the menu bar and follow the steps of the wizard. If the Keep this domain controller in the project option was selected for the domain controller, this DC will have "Removed, but remained in the project" status after comparing the project with live Active Directory® and will remain in the project after the project update.

Phase 2

To promote new domain controllers and re-promote/demote existing ones

  1. Open your project with domain controllers that were restored from a backup before.

  2. On the menu bar, click Tools | Recovery Project Settings.

  3. Open the Recovery Mode tab.

  4. In the Recovery mode drop-down list, select Repromotion.

  5. You cannot select domains for recovery. All domains are involved in recovery.

  6. Optionally, you can specify default credentials to access domain controllers in the selected domains.

  7. Now the Do nothing recovery mode is set for all running domain controllers that were recovered during Phase 1. This recovery mode does not perform any actions on the domain controller itself and does not remove it.

  8. For domain controllers that were not restored during Phase 1, the Reinstall Active Directory recovery method is selected by default. Also, a user can use the Install from Media option or change Reinstall Active Directory to any other available recovery method.

  9. Start the recovery process. The recovery process can be repeated many times - restore several not restored DCs, then restore the remaining DCs.

 

Managing Forest Recovery Agent

Recovery Manager for Active Directory (RMAD) employs a Forest Recovery Agent to recover domain controllers. For this reason, it is recommended that you install Forest Recovery Agent on each domain controller you want to recover with RMAD.

NOTE

To install, delete or upgrade the Forest Recovery Agent, RMAD uses the domain access credentials. For more details see the General tab section.

RMAD uses the Secure Remote Procedure Call (RPC) over Secure Sockets Layer (SSL) communication logic to establish secure connection between Forest Recovery Console and the Forest Recovery Agent based on the Microsoft Secure Channel (SChannel). The process of agent installation starts with generating the Console and Agent communication keys on the console side, then these keys are deployed to the agent host. After the keys are deployed, both sides verify that each other has a valid key to provide the mutual authentication without using the domain access credentials.

If Forest Recovery Agent is not installed a domain controller in your recovery project, RMAD attempts to automatically install the Forest Recovery Agent on that domain controller after you start the recovery operation on the project.

After you have upgraded the Forest Recovery Console to a new version, it is recommended that you manually upgrade the Forest Recovery Agent on each domain controller in your recovery projects to the version supplied with the new Forest Recovery Console. By doing so you ensure the Forest Recovery Console and the Forest Recovery Agent are fully compatible and can correctly communicate with each other after the upgrade.
