Bare metal restore is a system restoration process in which an identical computer image/instance is created on a bare metal computer from the ground up. It allows a computer to be restored without preinstalled software, with the exception of the firmware or basic input/output system (BIOS).
Bare metal restore is also known as tier 1 restore.
Bare metal restore is performed in enterprise computing environments where exact replicas of computer systems are required in the event of disaster. It is implemented through specialized software that copies an entire image of a source computer as a system image that is held by the system image creation or backup software. The image may be easily transported, installed and restored on a new or older system without data on the hard disk drive (HDD). The system image seamlessly integrates on the bare metal system, providing the same software, applications, preferences and data to the new system.
Bare metal restore generally requires the same hardware configuration as the source computer and target bare metal computer.
