Relax-and-Recover (ReaR) is the de facto standard bare metal disaster recovery framework on Linux, shipped with Red Hat, SUSE, Ubuntu, Debian, and Fedora. Despite its widespread adoption, documentation has historically been minimal — limited to man pages and scattered blog posts.
Good documentation takes time and comes with a cost. ReaR has been maintained by volunteers and a single lead developer (Gratien D’haese of IT3 Consultants) for nearly 20 years, with limited bandwidth for comprehensive documentation. Community requests for better guides have grown steadily. The ReaR User Guide Documentation project was started in 2019 to fill that gap and grow into a full-fledged resource covering setup, configuration, advanced use cases, and troubleshooting.
Writing quality documentation is intensive work. If your organisation relies on ReaR in production, consider sponsoring the User Guide through a ReaR subscription or directly via PayPal:
Each sponsor is added to the SPONSORS file (or listed as “anonymous” on request). Sponsorship funds guaranteed weekly time spent on User Guide development and also supports ongoing ReaR software maintenance.
