Using Managed Service Accounts

Recovery Manager for Active Directory (RMAD) supports MSA/gMSA accounts for:

  • Scheduled backups - the account can be specified for scheduled tasks in the Computer Collection properties on the Schedule tab or in Task Scheduler.

  • Scheduled replication tasks (Fault Tolerance)

  • Scheduled verification of a Forest Recovery project

  • The Recovery Manager Portal can be run under the MSA/gMSA account. During the Recovery Manager Portal installation, specify the MSA/gMSA on the Specify Web Site Settings step of the wizard.

MSA/gMSA account requirements:

  • You can use Managed Service Account (in Windows Server 2008 or higher) or Group Managed Service Account (in Windows Server 2012 or higher).

  • Add the $ character at the end of the account name (e.g. domain\computername$) and leave the Password field blank.

  • The MSA/gMSA account must be a member of the local Administrator group on the RMAD machine.

  • For more details about account requirements and limitations related to Recovery Manager Portal, see the Install or uninstall Recovery Manager Portal section in Permissions required to use Recovery Manager for Active Directory.

How to create a Group Managed Service Accounts (gMSA)

  1. Create a gMSA account in Active Directory using the following command: New-ADServiceAccount -name @<gMSA account name> -DNSHostName @<DNS host name>

  2. Run Install-AdServiceAccount @<gMSA account name> on each host where you are going to use this gMSA account.

What are the steps to configure a gMSA account for use as the backup agent account using the minimum permissions model?

  1. Create а gMSA and associate its principal with the computer accounts of the member hosts. If you want to manage the service host permission to use a gMSA account by a security group, you can associate the account principal with a security group. And then assign the RMAD server(s) machine accounts as members of the linked security group.

  2. Create the Active Directory group RMAD Backup Operators and add the gMSA account to this group directly.

  3. If using pre-installed agents, uninstall and reinstall the agents. This is required to populate the RMAD Backup Operators group SID locally on the DCs.

  4. Configure the collection properties to set the backup agent access account. When entering the gMSA credentials, input the username as "domain\gMSA$", where gMSA is the service account login name followed by the $ sign, and leave the password fields blank.

Take consideration that some items are not possible to configure when using the minimum permissions group, such as "Ensure Forest Recovery Agent is deployed". This setting requires that you have DC Administrator access, and access to the admin$ share. If you want to have this set up, the gMSA will need to be a member of Domain Admins, instead of RMAD Backup Operators.

Active Directory backups vs Windows System State backups

The Active Directory and Windows System State backups are very similar. The key components that Recovery Manager for Active Directory (RMAD) backs up as part of the AD system state are the Registry, the NTDS.dit file, and SYSVOL.

What differences do they have?

  • Windows System State backup is a full backup of the Windows operating system; Active Directory backup contains only pieces of Active Directory that allow you to restore the domain controller on a clean operating system.

  • Windows System State backups contain more components - not all of these components are necessary for Active Directory recovery, e.g. IIS Metabase, Cluster Services, etc.

  • Windows System State backup may contain viruses in the components of the operating system.

  • Windows System State backups are larger than Active Directory backups.

For the list of Windows System State backup components, see Microsoft documentation.

RMAD enables the backup and restoration of the following Active Directory components on domain controllers:

  • DIT Database

  • SYSVOL

  • Registry, including all registry hives and the file NTUSER.DAT

RMAD Disaster Recovery Edition also supports Bare Metal Recovery (BMR) backups. With BMR backups, you can completely rebuild the server if necessary.

 

Creating BMR and Active Directory backups

Recovery Manager for Active Directory (RMAD) allows you to create backups of system-specific data known as the Active Directory and BMR backups. Note that RMAD creates Active Directory backups for Active Directory domain controllers only.

NOTE

If you are going to store backups on the Recovery Manager Console machine, check that the Administrative Share "DriveLetter$" exists and is accessible on this host. Otherwise, the backup operation will fail. For more information, see Installing Backup Agent automatically.

You can use Computer Collections to create backups for multiple computers. For more information, see Using Computer Collections.

 

Creating Active Directory backup

NOTE

When the backup is triggered and any specified backup path is not available, no backup is created, neither in the remote storage nor in the local storage. The backup creation session will fail.

To create backups of all computers in a Computer Collection
  1. In the console tree, select a Computer Collection, and then click Create Backup on the Action menu.

  2. If prompted, confirm the operation.

You can also use the Backup Wizard to start a backup job:

  1. In the console tree, click the root node, and then click Create Backup on the Action menu.

  2. Follow the instructions in the Backup Wizard.

  3. On the When to Back Up page click Now, and then click Next.

  4. Click Advanced to view backup options. You can modify the options as needed. When finished, click OK to close the Properties dialog box.

  5. Click Finish to start the backup job.

Note

By default, the wizard uses the default settings. You can view and modify the default settings using the Collection Defaults command that appears on the Action menu when you select the Computer Collections node in the console tree.

With the Backup Wizard, backup jobs can be scheduled to run at a specific time. For more information, see Scheduling backup creation subsection of Task scheduler overview.

While a backup job is running, you can examine the progress of the operation and, if needed, stop the backup job. After a backup job is completed, you can view backup creation results:

  1. In the console tree, click Sessions.

  2. In the details pane, click the backup-creation session, and then click Properties on the Action menu.

  3. In the Properties dialog box, click the Progress tab, and examine the displayed information.

  4. By clicking Abort on the Progress tab, you can stop the selected session.
