    Reading

    ReaR is the standard way to rebuild a failed Linux server or move it to new hardware, and it ships with RHEL and SLES. It is a component, not a backup system: pair it with Bareos, Bacula or another product for the data itself.

    Open questions and evidence caveats

    • Linux only; no Windows bare-metal recovery.
