The necessity of backing up Active Directory
Active Directory (AD) is a directory service that Microsoft developed for the Windows domain networks. It is included in most Windows Server operating systems as a set of processes and services. Users manage permissions and access to networked resources through AD.
It is necessary to backup Active Directory 2008/2012/2016 because:
You may accidentally delete a user account or an Organizational Unit (OU) in Active Directory. A backup of AD will help you recover those objects easily.
The Active Directory database may be corrupted from server updates. With a backup at hand, you can restore it to the normal state as you wish.
Then, what Active Directory backup tools should you choose? Please read on.
Backup Active Directory with Windows Server Backup
Windows Server Backup (WSB) is a backup and recovery tool first introduced in Windows Server 2008. To back up AD, you typically back up the full server. As WSB is not installed by default, you need to install it by yourself and then perform a full server backup with it. Let’s take Windows Server 2012 R2 as an example:
▶ Install Windows Server Backup
1. Open Server Manager and click Add roles and features.
2. On the Add Roles and Features Wizard, click Next.
3. On the Installation Type screen, leave the default Role-based or feature-based installation and click Next.
4. Click Next respectively on the Server Selection screen and the Server Roles screen.
5. On the Features screen, select Windows Server Backup and click Next.
6. Click Install. Wait for the installation process to be completed. Click Close to exit the Add Roles and Features Wizard.
▶ Backup Active Directory with Windows Server Backup
1. Open Server Manager, click Tools in the upper-right column and select Windows Server Backup.
2. Click Local Backup. On the Action menu, click Backup once.
3. In the Backup Once Wizard, on the Backup options page, click Different options, and then click Next.
4. On the Select backup configuration page, click Full server (recommended), and then click Next.
5. On the Specify destination type page, click Local drives or Remote shared folder, and then click Next.
6. On the Select Backup Destination page, choose the backup location. If you selected local drive, choose a local drive; if you selected remote share, choose a network share.
▪ If you get an error stating that no backup storage location is available, you will need to either exclude one of the volumes that has been selected or add a new volume or remote share.
▪ If you get a warning stating that the selected volume is also included in the list of items to backup, determine whether to remove it by clicking OK or not.
7. On the confirmation screen, click Backup. Once this has completed, click Close to exit the Backup Once Wizard.
8. Close Windows Server Backup.
After you backup Active Directory 2008/2012/2016 with Windows Server Backup, you may choose different recovery methods when you encounter Active Directory issues. A non-authoritative restoration is needed when it has something to do with the system. In this situation, you perform a normal system-state restoration and then boot the server.
If you have accidentally deleted an object in AD, an authoritative restore is suitable. In this case, the steps are same as a non-authoritative restoration except that you should run Ntdsutil command with the appropriate options before reboot.
The whole process of backup & recovery with WSB seems complicated and error-prone. Is there an easier way to backup and restore Active Directory? Certainly there is!
