19.0 Disaster Recovery with Rear

Relax-and-Recover (formerly ReaR, in this chapter abbreviated as Rear) is a disaster recovery framework for use by system administrators. It is a collection of Bash scripts that need to be adjusted to the specific production environment that is to be protected in case of disaster.

No disaster recovery solution will just work out-of-the-box. Therefore it is essential to take preparations before any disaster happens.
