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.
