Overview
Clonezilla is a free disaster recovery, disk cloning, disk imaging and deployment solution. Clonezilla is designed by Steven Shiau and developed by the NCHC Free Software Labs in Taiwan. Clonezilla Server Edition provides multicast support similar to Norton Ghost Corporate Edition.
Clonezilla, based on DRBL, Partclone and udpcast, allows you to do 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. At the NCHC's Classroom C, Clonezilla SE was used to clone 41 computers simultaneously. It took only about 10 minutes to clone a 5.6 GBytes system image to all 41 computers via multicasting.
Features and Benefits:
Clonezilla provides the following features and benefits:
- Free (GPL) Software.
- Filesystem supported: (1) ext2, ext3, ext4, reiserfs, reiser4, xfs, jfs of GNU/Linux, (2) FAT, NTFS of MS Windows, (3) HFS+ of Mac OS, (4) UFS of FreeBSD, NetBSD, and OpenBSD, and (5) VMFS3 of VMWare ESX. Therefore you can clone GNU/Linux, MS windows, Intel-based Mac OS, and FreeBSD, NetBSD, and OpenBSD, 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.
- 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.
- 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.
Limitations:
Clonezilla has the following limitations:
- The destination partition must be equal or larger than the source one.
- Differential/incremental backup is not implemented yet.
- Online imaging/cloning is not implemented yet. The partition to be imaged or cloned has to be unmounted.
- Software RAID/fake RAID/firmware RAID is not supported by default. It's can be done manually only.
- Due to the image format limitation, the image can not be explored or mounted. You can _NOT_ recovery single file from the image. However, you still have workaround to make it, read this.
- Recovery Clonezilla live with multiple CDs or DVDs is not implemented yet. Now all the files have to be in one CD or DVD if you choose to create the recovery iso file.

What's new in Clonezilla 2.3.1-18
This build includes a number of enhancements and bug fixes.
Enhancements and changes:
- The underlying GNU/Linux operating system was upgraded. This release is based on the Debian Sid repository (as of 2014/Dec/08).
- Linux kernel was updated to 3.16.7-2.
- Package drbl was updated to 2.11.13-drbl1, and clonezilla was updated to 3.12.7-drbl1.
- Syslinux was updated to 6.03.
- Language files de_DE, ca_ES, es_ES, fr_FR, it_IT, ja_JP.UTF-8, tr_TR and sk_SK was updated. Thanks to Michael Vinzenz, Juan Ramón Martínez, René Mérou, Jean-Francois Nifenecker, Gianfranco Gentili, Akira YOSHIYAMA, Volkan GEZER and Ondrej Dzivy Balucha.
- A mechanism was added to check if i386 library (libc6-i386 or glibc.i686) exists on x86-64 system when running makeboot.sh due to syslinux included in Clonezilla live is 32-bit.
- Linux kernel i486 was replaced by i586 because now only i586 kernel exists on Debian Sid repository.
- A better way to deal with --rsyncable option of gzip and pigz was implemented. (https://sourceforge.net/p/clonezilla/discussion/Open_discussion/thread/8d5f80a6/)
- Adding support for device name format like /dev/rd/c0d0 and /dev/ida/c0d0 RAID cards. (https://sourceforge.net/p/clonezilla/discussion/Clonezilla_live/thread/e82e1c04/)
- Now Clonezilla could support PV on disk, not only on partition.
- Fake RAID/firmware RAID is now supported if its device naming style is /dev/md.
- The partition from an image could be now restored to different name device, e.g. sda1 could be restored to sdb5.
Bug fixes:
- Temporarily disabled vmfs3 and vmfs5 support due to an issue (https://github.com/glandium/vmfs-tools/issues/12). Now dd is used for vmfs. Now waiting for the updating of vmfs-tools.
- Options "-fsck-src-part" and ""-fsck-src-part-y" were duplicated in ocs-onthefly expert mode.
- The input harddrive of ocs-install-grub might be more than one, therefore ocs-install-grub should take that into consideration.
- Only device name /dev/mmcblk0p worked. Those /dev/mmcblk[1-9]p were not supported.
