## What it is
Relax-and-Recover (ReaR) is a Linux bare metal disaster recovery and system migration tool that creates bootable rescue images and automates storage recreation, backup restore, and bootloader installation on replacement hardware. It integrates with many built-in and commercial backup solutions and is the de facto standard DR framework on enterprise Linux.

## Use cases
- recover a Linux server from a broken hard disk onto bare metal
- create a bootable USB rescue image for disaster recovery
- migrate a Linux system to new hardware
- integrate bare metal recovery with NetBackup, Bacula, or Bareos
- recreate disk partitions and filesystems after a failure
- set up an enterprise disaster recovery policy on RHEL or SLES

## When to choose
- you need bare metal recovery for physical or virtual Linux machines
- you run enterprise Linux (RHEL, SLES) and need a standard DR framework
- you want to integrate existing backup software with automated recovery
- you need a setup-and-forget rescue image solution

## When to avoid
- you need full backup management with scheduling and catalogs
- your primary systems are not Linux
- you only need simple file-level backups without recovery automation

## Facets
- artifact type: cli-tool
- maturity: active
- function: backup, deployment, developer-tools
- domain: self-hosted, operating-systems
- platform: cli
- tags: disaster-recovery, bare-metal-restore, system-migration, rescue-image, backup-integration, devops, linux
