Ermine, a company specializing in packing GNU/Linux applications together into a single executable, are working with Bacula Systems to bring new functionality to Bacula Systems’ backup and restore technology. The result is Linux Bare Metal recovery, a new feature now available in Bacula Enterprise Edition.
Bare-metal restore is a technique in the field of data recovery and restoration where the backed up data is available in a form which allows one to restore a computer system from “bare metal”, i.e. without any requirements as to previously installed software or operating system.
The backed up data itself can include an entire operating system – bootable from Bacula System’s USB Key – which contains a static Bacula client built with Ermine, and has all the components and required application code to call Bacula’s Director and create and restore the disk images.
Ermine creates Tools for professional software deployment. Ermine packs a GNU/Linux application together with any needed shared libraries and data files into a single executable, and this file can be copied to any GNU/Linux host and run without further modifications. The advantages of this approach are many, such as becoming independent of host configurations; independence from package management; and no version mismatch between the executable and its auxiliary files. In addition, there are no host-dependent side-effects; the application and the target host’s software environment do not interfere with each other.
