Clonezilla for Disk Imaging and Cloning.

Posted: Saturday, September 6, 2014 by Mahmoud Ramadan Ali in Labels:

Clonezilla is a partition and disk imaging/cloning program similar to True Image® or Norton Ghost®. It helps you to do system deployment, bare metal backup and recovery. Two types of Clonezilla are available, Clonezilla live and Clonezilla SE (server edition). Clonezilla live is suitable for single machine backup and restore. While Clonezilla SE is for massive deployment, it can clone many (40 plus!) computers simultaneously. Clonezilla saves and restores only used blocks in the harddisk. This increases the clone efficiency. With some high-end hardware in a 42-node cluster, a multicast restoring at rate 8 GB/min was reported.

Features:
-Free (GPL) Software.
-Filesystem supported: (1) ext2, ext3, ext4, reiserfs, reiser4, xfs, jfs, btrfs of GNU/Linux, (2) FAT12, FAT16, FAT32, NTFS of MS Windows, (3) HFS+ of Mac OS, (4) UFS of FreeBSD, NetBSD, and OpenBSD, (5) minix of Minix, and (6) VMFS3 and VMFS5 of VMWare ESX. Therefore you can clone GNU/Linux, MS windows, Intel-based Mac OS, FreeBSD, NetBSD, OpenBSD, Minix and VMWare ESX, no matter it's 32-bit (x86) or 64-bit (x86-64) OS. For these file systems, only used blocks in partition are saved and restored. For unsupported file system, sector-to-sector copy is done by dd in Clonezilla.
-LVM2 (LVM version 1 is not) under GNU/Linux is supported.
-Boot loader, including grub (version 1 and version 2) and syslinux, could be reinstalled.
-Both MBR and GPT partition format of hard drive are supported. Clonezilla live also can be booted on a BIOS or uEFI machine.
-Unattended mode is supported. Almost all steps can be done via commands and options. You can also use a lot of boot parameters to customize your own imaging and cloning.
-One image restoring to multiple local devices is supported.
-Multicast is supported in Clonezilla SE, which is suitable for massively clone. You can also remotely use it to save or restore a bunch of computers if PXE and Wake-on-LAN are supported in your clients.
-The image file can be on local disk, ssh server, samba server, or NFS server.
-Based on Partclone (default), Partimage (optional), ntfsclone (optional), or dd to image or clone a partition. However, Clonezilla, containing some other programs, can save and restore not only partitions, but also a whole disk.
-By using another free software drbl-winroll, which is also developed by us, the hostname, group, and SID of cloned MS windows machine can be automatically changed.

Which Clonezilla Shall I Use ?

Clonezilla Live: Clonezilla live allows you to use CD/DVD or USB flash drive to boot and run clonezilla (Unicast only)
Clonezilla SE: Clonezilla SE is included in DRBL, therefore a DRBL server must first be set up in order to use Clonezilla to do massively clone (unicast, broadcast and multicast are supported)
