What is a bare metal recovery?

Bare metal recovery (BMR) is a feature of Windows Server Backup that allows you to restore your operating system (OS) or the entire system to another machine with dissimilar hardware from “bare metal”. It does not require any installed software or system on the destination machine, so you can also use BMR to restore physical machine to virtual machine and back.

What do you need to prepare?

Windows Server Backup (WSB) was first introduced in Windows Server 2008. To perform bare metal restore, you need to create a bare metal backup of Windows Server 2008 (R2), 2012 (R2), or 2016. When creating the Windows Server bare metal backup with WSB, you need to select the item for Bare Metal Recovery.

Make sure the destination hard drive to receive the bare metal recovery has enough disk space. If you want to restore to a new machine, the new hard drive needs to be the same size or large than the source disk that was backed up regardless of the size of the data.
