Bare Metal Restore Definition
Bare Metal Restore (BMR), or bare metal recovery, is a data recovery process that involves restoring a complete system (operating system, applications, and data) to a new or empty hard drive from a backup. It can be used to completely restore an entire virtual server, physical servers, and cloud servers.
This is typically done when a system has failed and cannot be booted up or when migrating to new hardware.

Complete System Restoration:
BMR restores everything needed to get a system back up and running exactly as it was before the failure or migration.
“Bare Metal” Refers to an Empty Hard Drive/Server:
The term “bare metal” signifies that the target hard drive for the restoration is empty or unformatted, like a blank slate.

Essential for Disaster Recovery:
BMR is often used when a quick and complete system restoration is required in disaster recovery scenarios.
Useful for Hardware Upgrades or Replacements:
BMR allows for seamless system migration to new hardware without tedious reinstallation and configuration processes.

How it works:
- Create a Backup:
A full backup of the system, including the operating system, applications, configurations, and data, is created and stored on a separate device or location. - System Failure or Migration:
The original system fails or is replaced with new hardware. - Boot from Recovery Media:
The recovery media (e.g., a bootable USB drive or CD) containing the BMR software is used to boot up the new or empty system. - Restore from Backup:
The BMR software guides the user through the process of selecting the backup and restoring it to the target hard drive. - The system is Restored:
Once the restoration is complete, the system should be back to its previous state and fully operational.
