Relax and Recover (abbreviated rear) is a highly modular disaster
recovery framework for GNU/Linux based systems, but can be easily
extended to other UNIX alike systems. The disaster recovery information
(and maybe the backups) can be stored via the network, local on hard
disks or USB devices, DVD/CD-R, tape, etc. The result is also a
bootable image that is capable of booting via PXE, DVD/CD and USB
media.

Relax and Recover integrates with other backup software and provides
integrated bare metal disaster recovery abilities to the compatible
backup software.
