Goal

Relax-and-Recover (ReaR) is an Open Source based system backup and recovery solution that is natively provided as part of Oracle Linux (OL).
The backup procedure produces a bootable image for the system to initiate recovery.
The boot image can be used to re-partition the system, initiate system restore from available backups and perform restoration to different hardware.
ReaR supports various boot media (ISO, PXE, OBDR tape, USB or eSATA storage) and a wide variety of network protocols (SFTP, FTP, HTTP, NFS, CIFS).

This document serves as an example guide to install and configure ReaR for backup to and restore from NFS storage.
