Bare metal recovery is a way to restore a complete system onto new hardware after a failure or cyberattack. This is a key part of disaster recovery for IT environments.
What is Bare Metal Recovery?
Bare metal recovery (sometimes called bare metal restore or bare metal backup) means bringing a system back to its original state from scratch, even if the hardware has been replaced or wiped clean. You don’t need a working operating system or applications on the machine before you start. Everything – OS, settings, data – gets restored from your backup.
How Bareos Handles Bare Metal Recovery
Bareos supports bare metal recovery for Linux and, starting with Bareos 25, Windows systems too. This lets you recover both servers and workstations after hardware failure, ransomware attacks or major corruption.
- Linux bare metal recovery: Bareos integrates with Relax-and-Recover (ReaR), an open-source Linux disaster recovery tool. ReaR works with Bareos to create recovery images and automate the restore process. This includes system configuration, installed packages and data.
- Windows bare metal recovery: With Bareos 25, you can do full bare metal restore for Windows systems. This means you can recover a Windows machine without manual reinstallation.
Why consider Bareos for Bare Metal Recovery?
- Disaster recovery: Bare metal restore lets you recover quickly after hardware loss, ransomware, or other disasters.
- Flexible backup: You can back up and restore both Linux and Windows systems.
- Automation: Integration with tools like ReaR streamlines the recovery process.
- Open-source: Bareos and ReaR are open-source, so you can inspect, adapt, and extend them to fit your needs.
How it Works
For Linux systems, you install and configure ReaR, which works with Bareos to:
- Back up the entire system, including configuration and data.
- Create a bootable recovery image.
- Restore the system to new or repaired hardware.
For Windows systems (starting with Bareos 25), Bareos offers similar bare metal recovery options, allowing you to restore everything to new hardware in case of failure.

Bareos provides professional bare metal backup and recovery for both Linux and Windows environments. With features for automation, cross-platform support and open-source flexibility, Bareos is a solid choice for disaster recovery and system restore needs.
