Bare Metal Backup and Restore
From my last post, the concept of bare-metal backup was mentioned as one of the features of the "Clonezilla" software. It sounds kind of exotic, so I decided to make a whole post on the subject. Basically, a bare-metal backup is one that allows you to restore your hard drive from the ground up with only two software components. 1. A file utility like Clonezilla. 2. The cloned hard drive image. And lastly, I can assure you it does not involve any sanding, grinding, or welding.

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.
Typically, the backed up data includes the necessary operating system, applications and data components to rebuild or restore the backed up system to an entirely separate piece of hardware. In some configurations, the hardware receiving the restore needs to have an identical configuration to the hardware that was the source of the backup, although virtualization techniques and careful planning can enable a bare-metal restore to a hardware configuration different from the original.
Disk imaging applications enable bare-metal restores by storing copies (images) of the entire contents of hard disks to networked or other external storage, and then writing those images to other physical disks. The disk image application itself can include an entire operating system, bootable from a live CD or network file server, which contains all the required application code to create and restore the disk images.
