Copying a device with dd

dd allows you to make an exact copy of a device. It is ideally suited to back up and restore a complete filesystem. …

To copy or clone a device, as root: "dd if=/dev/sdb of=backup.img" (replacing sdb with your device).

To restore the image to the same or any other device of the same size, as root: "dd if=backup.img of=/dev/sdb" (again, replacing sdb with your device).
