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 tape (OBDR).
