![]() A network with only one domain controller (DC).įurther in the article, we will consider two possible network configurations: Microsoft Active Directory services use a database located on the file system of a domain controller.There are more than one domain controller in a network and the information stored in the database is constantly replicated between multiple domain controllers.While the backup process doesn't vary much for these network setups, the restore process will be different. How to backup the Microsoft Active Directory Here’s how you perform a backup of the Active Directory using the image-based backup feature in CloudBerry Backup. Image-based backup allows the backup and recovery of the whole computer including the state and the structure of its drives and the operating system. Thus, it allows us to back up the domain controller’s system volume, boot volume, and the volumes where the AD database and transaction logs are located.īy default, the Active Directory database is located in the %systemroot%\NTDS folder (C:\Windows\NTDS) of a domain controller. ![]() Since the database and the transaction logs may be stored on different volumes make sure to include both in the backup. Let’s consider several possible scenarios when you need to recover the Active Directory How to recover the Microsoft Active Directory When the backup is done - you have all the information required to recover the domain controller from scratch to new hardware (so-called bare metal recovery) with previously saved Active Directory settings. There was only one DC in the domain and this DC has crashed or when all domain controllers are lost.Īctive Directory database is corrupted and the AD service doesn’t start. Here are the steps to recover the last or the only domain controller to new hardware: Some critical files were accidentally deleted from the Active Directory. Install CloudBerry Backup for Windows on a server with similar hardware and create a bootable USB device. If you are not yet familiar with the Bare metal recovery process please refer to this step by step guide on how to perform it:Ĭonfigure a Restore plan and make sure to select the latest available backup. This is especially important since all the information created since the last backup will be lost. Run the CloudBerry Backup Restore process. Reboot the computer and make sure the Active Directory service has started successfully.NOTE: If your domain has only one domain controller, it is a good idea to run a backup at least daily.
