Recovery Manager for AD Disaster Recovery Edition 10.2.2 - User Guide

Selecting backups for recovery

You can only restore domain controllers from backups created with Recovery Manager for Active Directory. The Forest Recovery Console provides the following methods for you to select backups for recovery:

• Method 1: Automatically select backups based on your criteria. Allows you to automatically select specific backups for multiple domain controllers according to the backup selection criteria you specify.

• Method 2: Manually select backups. Allows you to manually select any backup for a given domain controller in the recovery project. You can only select from backups created with Recovery Manager for Active Directory.

The next sections describe each of these methods.

Method 1: Automatically select backups based on your criteria

You can use the Forest Recovery Console to automatically select backups for multiple domain controllers in your recovery project. This method allows you to specify a time period, and then automatically select the latest backup created in that period for particular domain controllers in the project.

To automatically select backups

Specify your backup selection criteria:

1. Create or open a recovery project.

2. On the Forest Recovery Console toolbar, click Backup Criteria.
   
   
   
   
   
   
   
   

3. Automatic backup selection criteria can be defined based on backup type:

   Select All Backups to apply the same search criteria to both BMR and AD Backups,

   Select BMR Backups to apply specified search criteria to BMR backups only.

   Select AD Backups to apply specified search criteria to AD backups only.

   

   Automatic backup selection options

   Option	Description
   Use the latest backup, but not older than 60 days	Allows you to use the most recent backup registered with Recovery Manager for Active Directory (RMAD) for a given domain controller.
   Use latest backup created before <Date> and after <Date>	Allows you to specify a date range and use the most recent backup from that range for a particular domain controller.
   Use backups on DCs whenever possible	Not supported for BMR backups. When this check box is selected, RMAD first searches DCs to be restored for backups that meet the criteria you have specified. If no suitable backups found on the DCs, RMAD will search the Forest Recovery Console computer for backups. By selecting this check box, you can avoid unnecessary backup file copying from the Forest Recovery Console to the DCs to be restored and thus speed up the recovery process.

When you are finished, click OK.




Specify the domain controllers for which you want to automatically select backups:

• Hold down CTRL, and then click to select such domain controllers in the list of domain controllers.

• Open the General tab, and then select the Use backup criteria to automatically select a backup check box.

To view which backup was automatically selected for a domain controller, select that domain controller in the list, open the Settings tab, and see the backup file path and name in the Backup file box.

To manually select a different backup, clear the Use backup criteria to automatically select a backup check box, and click the Select button to select a backup.

Method 2: Manually select backups

This method allows you to manually select any backup for a given domain controller in the recovery project. You can only select from backups registered with Recovery Manager for Active Directory.

To manually select a backup

1. Create or open a recovery project.

2. In the list of domain controllers, select the domain controller for which you want to select a backup.

3. Open the General tab, and then click the Select button next to the Backup file box to select a backup.

Using recovery alerts

Recovery alerts provide you with the real-time information about the recovery of domain controllers in your project. You can configure a recovery alert to inform you when particular domain controllers complete the recovery stage you specified in the alert settings.

For a recovery project, you can create and configure multiple alerts, each having different settings. You can also modify settings of existing alerts or delete alerts as necessary. To manage recovery alerts, click the Configure Alerts button on the toolbar of the Forest Recovery Console.

For each alert, you can select one or more domain controllers to which the alert will apply. You can configure an alert to inform you about the completion of one or more of the following recovery stages on the target domain controllers:

Recovery stages for which you can use alerts

Prepare to restore from backup

During this stage, Recovery Manager for Active Directory (RMAD) verifies that the backup files you selected for recovery are available on the target domain controllers. If necessary, RMAD copies the backup files that are missing. Also, RMAD disables Microsoft Windows Update if it is enabled on the domain controllers.

Perform restore from backup

During this stage, RMAD performs the following steps:

• Detect current mode (DSRM or normal)

• Reset DSRM administrator password

• Restart domain controller in DSRM

• Enable domain controller isolation

• Disable BitLocker

• Disable custom password filters

• Restore data from backup

• Restart domain controller in normal mode

• Reset DSRM administrator password

Configure domain controller

During this stage, RMAD performs the following steps:

• Get information about domain controller

• Select preferred DNS server

• Remove global catalog (if you did not specify to keep the existing global catalog)

• Raise RID pool

• Invalidate RID pool

• Seize FSMO roles

• Clean up metadata of removed domain controllers

• Reset the Krbtgt password

• Reset password for users in privileged groups

• Reset computer account passwords

• Enable custom password filters

• Restart domain controller in normal mode

• Reset trust passwords

Make domain controller available

During this stage, RMAD performs the following steps:

• Ensure that domain controller isolation is disabled

• Clean up metadata of unrecovered domains if necessary

• Change global catalog partition occupancy level

• Add global catalog (if you did not specify to keep the existing global catalog)

• Wait for a global catalog server to become available

• Restore initial global catalog partition occupancy level

• Enable the use of global catalog for user authentication

• Enable BitLocker

• Enable Windows Update (if it was enabled before the recovery)

• Remove temporary files

Uninstall Active Directory® Domain Services

During this stage, RMAD uninstalls Active Directory® using the tools provided by Microsoft. For domain controllers running Windows Server® 2008 or earlier, RMAD uses the Dcpromo.exe tool. For Windows Server® 2012-based domain controllers, RMAD uses the Windows PowerShell® cmdlet Uninstall-ADDSDomainController.

Also, RMAD disables Microsoft Windows Update if it is enabled on the domain controllers.

Reinstall Active Directory® Domain Services

During this stage, RMAD performs the following steps:

• Select preferred DNS server

• Wait for a global catalog server to become available

• Reinstall Active Directory® Domain Services

• Remove temporary files

• Enable Windows Update (if it was enabled before the recovery)
