Bare-Metal Recovery Guide

What Is Bare-Metal Recovery?

Bare-Metal Recovery (or Bare-Metal Restore, or BMR) is a backup recovery technique that allows you to recover data on a computer with no installed operating system - also called a bare-metal machine. To achieve this, you will need a system image of the computer that you would like to recover. This saves time while installing and configuring a new machine.

Use Cases

Diagram showing how bare-metal recovery works

Bare-metal restore is helpful when you need to rebuild your computer infrastructure quickly:

    • After ransomware attacks
    • When hardware fails unexpectedly
    • When disaster recovery is needed

You can also use bare-metal restore technique in order to configure a number of machines in the same way using a so-called ‘master image’ to restore on all those machines.

All cases require a completely free storage media: without any data, software and operating system.

Advantages

Bare-metal recovery advantage: faster than manual recovery No need to install software or operating system, thus faster than manual recovery

Bare-metal recovery advantage: less human interaction Less human interaction, thus less room for failure

Bare-metal recovery advantage: ability to automate server migration Ability to automate server migration to physical, virtual or cloud environments

The simplicity of this approach is unmatched, enabling you to restore the entire hardware infrastructure swiftly and conveniently.

How to Perform Bare-Metal Recovery

Typically the process of bare-metal restore includes recovery of a system image backup from an ISO image file or a USB flash drive that you boot on your machine to perform a restore.

Bare-Metal Restore to Dissimilar Hardware

Bare-metal restore can be an issue if you try to recover to a dissimilar hardware. Your operating system may fail to boot in case your hardware, where you’re trying to perform a restore, has different boot-critical devices - as compared to the machine where you created a system image.

In order to boot, operating system needs drivers of the following devices:

  • CPU
  • Motherboard
  • HDD controller

So if your system image has drivers that do not match these boot-critical devices of another machine, operating system on that machine will not be able to boot.

To prevent it, you can install additional drivers required for the hardware configuration where you will be performing bare-metal restore from your recovery disk.

CloudBerry Backup offers you fast and simple bare-metal restore process. It allows you to perform image-based backups to any cloud or local backup destination, restoring image-based backups as VMware virtual machines or Azure virtual machines.

 

Bare-metal recovery from USB or ISO fileBootable USB for Bare-Metal Restore

Easily create a recovery USB drive or bootable ISO file for an emergency recovery in case of a system or hardware crash. Install additional drivers for a hardware configuration that is different from the current machine.

 

Flexible retention and recoveryFlexible Retention and Recovery

Why recover only the latest version? CloudBerry Backup allows bare-metal restore to the point in time that you choose. Store as many versions as you need for as long as you need with flexible retention settings.

 

Compression and encryption

Compression and Encryption
CloudBerry supports on-point compression and encryption. Compression allows you to save space (and thus money) on the storage of your choice and time when performing backup. With AES-256 encryption and encrypted upload channels, you can be sure that all your files are safe.
