Relax-and-Recover (Rear) is a bare metal disaster recovery and system migration solution, similar to AIX mksysb or HP-UX ignite. It is composed of a modular framework and ready-to-go workflows for many common situations to produce a bootable image and restore from backup using this image. It can restore to different hardware, and can therefore be used as a migration tool as well. It supports various boot media (including tape, USB, or eSATA storage, ISO, PXE, etc.), a variety of network protocols (including SFTP, FTP, HTTP, NFS, and CIFS), as well as a multitude of backup strategies (including IBM TSM, HP DataProtector, Symantec NetBackup, Bacula, and rsync). It was designed to be easy to set up, requires no maintenance, and is there to assist when disaster strikes. Recovering from disaster is made very straight-forward by a 2-step recovery process so that it can be executed by operational teams when required. When used interactively (e.g. when used for migrating systems), menus help make decisions to restore to a new (hardware) environment.
Integrated with duply/duplicity support. systemd support has been added. Various small fixes and improvements to tape support, Xen, PPC, Gentoo, Fedora, multi-arch, storage layout configuration, and serial console integration.
This release adds support for multipathing, adds several improvements to distribution backward compatibility, improves ext4 support, makes various bugfixes, migrates HWADDR after rescovery, and includes better systemd support.

Major feature enhancements, Stable
Multi-system and multi-copy support on USB storage devices. Basic rsync backup support. More extensive exclude options. The new layout code is enabled by default. Support for Arch Linux. Improved multipath support. Experimental btrfs support.
Standardization of the command line. The default is quiet output; use the option -v for the old behavior. Boot images now have a comprehensive boot menu. Support for IPv6 addresses. Restoring NBU backup from a point in time is supported. Support for Fedora 15 (systemd) and RHEL6/SL6. Improved handling of HP SmartArray. Support for ext4 on RHEL5/SL5. Support for Xen paravirtualization. Integration with the local GRUB menu. Boot images can now be centralized through network transfers. Support for udev on RHEL4. Many small improvements and performance enhancements.
This release supports many recent distributions, including "upstart" (Ubuntu 7.10). It has more IA-64 support (RHEL5 only at the moment), better error reporting and catching, Debian packages (mkdeb), and improved TSM support.
