Target Server Considerations
This topic lists the requirements for the target servers where you want to restore the domain controllers for performing a forest recovery. See the Recover a Forest topic for additional information.
tip
Remember, target server refers to a server where you intent to restore a domain controller.
Target Server and Operating System Requirements
Consider the following when restoring domain controllers.
- The target servers must be isolated from the environment in such a way that they can't name-resolve the domain that is restored. The process of restoring a domain will fail if the server can see that a domain of that name already exists. Typically, you should configure DNS in the target environment used for forest recovery in a way that allows each server in that environment to see each other.
- The target server must be a base installation of the Windows Server operating system (OS).
- The target server OS version should be the same version as the source domain controllers from which the backups were created. For example, a backup from a Windows Server 2022 domain controller would need to be restored to a Windows Server 2022 target server.
- While restoring a domain controller, the product configures the ADDS role and other settings, so there is no requirement to have those in place.
When the Target Server is a Virtual Machine
Following are some considerations when the target server is a virtual machine.
- Memory and storage configuration for the virtual machine should match the hardware configuration of the domain controller from which you performed the backup.
- The virtual machine should be in an isolated environment (i.e., shouldn't be able to contact the source forest or domains).
- The virtual machines should allow File and Print Sharing through the firewall as well as Remote Management, if possible.
Network Bandwidth Requirement for the Restore Operation
Network bandwidth should be as fast as available but can operate efficiently with 100 Mbps. Slower bandwidth will result in a longer setup stage for the restore as you have to copy the backup container to the target server.
