Clonezilla is a suite of open source drive cloning, drive imaging and system deployment utilities used to simpify deployment and maintenance of a group of computers.[3][4][5] CloneZilla Server Edition uses multicast technologies to deploy a single image file to a group of computers on a local area network.[5] Clonezilla was designed by and developed by the NCHC Free Software Labs in Taiwan.[6][7][8][9]

CloneZilla is used to deploy operating systems to computers by imaging a single computer and then deploying that image to one or more systems.[3][10] It integrates several other open source programs to provide cloning and imaging capabilities.

Variants[]

There are two variants of CloneZilla: (1) CloneZilla Live (which is intended to be used for imaging a single computer) and (2) CloneZilla Server Edition (SE) (which is intended for mass deployment over a computer network).[4] Both use a preinstallation environment to load the software from a portable USB flash drive.[5] Both use , and PartImage to image the drive either over the network or to a locally-attached hard disk drive.[4] CloneZilla Server Edition (SE) additionally uses which provides multicasting support similar to the now-defunct Norton Ghost suite. CloneZilla works by copying used blocks on the storage device (i.e. SATA SSD, HDD or NVMe SSD).[4] It is intended to support a bare-metal deployment of an operating systems by booting from a preinstalled live environment.

Clonezilla Live[]

Clonezilla Live can image a single computer's storage media or a single partition on the media to an image file stored on a SSH server, Samba network share, locally-attached hard disk drive or to a network filesystem file-share.[4][5] Alternatively, CloneZilla Live can clone the data on one storage medium to another without the need to create an image file first. Image files can be deployed to the same or different computers as required.

Unlike Acronis Cyber Protect Home Office and Norton Ghost, CloneZilla lacks an agent that can be installed into the operating system. Instead, CloneZilla was designed under the assumption that the disk should be cloned without interfering with the operating system. It is booted from a preinstallation environment and operations are performed within a consistent environment.[5] The preinstallation environment can be booted from a USB flash drive, CD/DVD-ROM or Android mobile phone.[11][12]

Clonezilla Server Edition (SE)[]

Clonezilla Server Edition (SE) can clone many computers at the same time using multicast technology over a computer network.[13] Since such an environment is difficult to configure, users can download a Live disk that provides the operating system with all the necessary configurations already done.[4] Images are uploaded to an image repository configured by the user, which may be a local directory on the same server as CloneZilla SE or a remote location such as a network-attached storage that is accessed using SSH or Samba.

Effectiveness[]

CloneZilla is an effective tool for deploying software in training laboratories.[13][3][10] CloneZilla can sometimes be faster than propriety solutions (i.e. Norton Ghost, , Macrium Reflect, and ) for both full image backup and restoration but can be difficult to configure. CloneZilla lacks incremental and differential backup support (which may make deployment slower).[14]

Features[]

Filesystem Copying[]

CloneZilla uses information from the filesystem to determine which blocks on a drive require copying. This ensures that only the space currently in use on the drive is copied while empty space is ignored. CloneZilla supports several filesystems including: Linux-based filesystems (Ext2, Ext3, Ext4, ReiserFS, XFS, JFS and Btrfs); Windows (NTFS and FAT); LVM2 and some hardware RAID chip sets.[4] When an unsupported filesystem is imaged or cloned, CloneZilla falls back to copying the data using dd. The master boot record and other drive metadata is copied using dd by CloneZilla before using PartClone, PartImage or NtfsClone to copy the appropriate filesystem.

Compression[]

CloneZilla images can be split into smaller files and compressed to save space on the destination drive.[4]

PXE Booting[]

CloneZilla can be booted over a computer network using PXE booting techniques.[4]
