A feature-rich tool that scales well in terms of reach and application
Clonezilla is one of the most recommended tools on Linux forums for imaging an old disk to a bigger, new disk thanks to its ncursesbased front-end, which is intuitive to navigate. The menus offers sensible defaults so you’ll find yourself pressing ahead with the recommended options most of the time. Just make sure that the partition to be cloned isn’t mounted.
When cloning, you’re shown a list of disks or partitions, depending on whether you want to clone complete disks or individual partitions. You also get options to compress the cloned images using either the gzip, bzip2 or lzo compression algorithms. You can keep them in a locally attached device, such as a USB disk attached to the computer, or on another computer via the network.
In addition to cloning single machines, you can also use Clonezilla for multicast cloning via two available options. Clonezilla Server Edition requires setting up a Diskless Remote Boot in Linux (DRBL) server to broadcast images across the network. On a smaller network, you can use the Clonezilla Lite Server mode on the bootable CD to set up a temporary server.
Restoring individual partitions or complete disks from a clone isn’t a complicated process. You do have to ensure that the destination partition is equal to or larger than the source, as it can’t restore an image to smaller disks.
An oft-recommended tool for bare-metal cloning that works as advertised. It’s well documented and can be used to effortlessly clone single or multiple computers with relative ease.
Clonezilla can also clone partitions and disks on the fly, but we’d advise you to create and clone from images for safety
