Relax-and-Recover (ReaR) is a modular bare metal disaster recovery framework written in Bash and released under GPLv3. Before each release, every supported combination of Linux distribution, hardware architecture, backup method, and boot mechanism must be validated. That is a substantial matrix:
Testing this matrix manually before every release is not feasible. Disaster recovery exercises traditionally require manual intervention at each step — making automation genuinely difficult.
The ReaR Automated Testing project automates a targeted set of end-to-end disaster recovery scenarios: boot the rescue ISO, reconstruct disk layout, restore data, verify the system boots correctly. It was originally built for customers with an active ReaR support contract as an additional service, and is published as Open Source (GPLv3) so the whole community can benefit and contribute.
Past validated scenarios include:

Open Source software is free to use, but the engineering work behind it is not free to produce.
