You're probably familiar with the popular proprietary commercial package Norton Ghost®, and its OpenSource counterpart, Partition Image. The problem with these software packages is that it takes a lot of time to massively clone systems to many computers. You've probably also heard of Symantec's solution to this problem, Symantec Ghost Corporate Edition® with multicasting. Well, now there is an OpenSource clone system (OCS) solution called Clonezilla with unicasting and multicasting!

Clonezilla, based on DRBL, Partition Image, ntfsclone, and udpcast, allows you to do bare metal backup and recovery. Two types of Clonezilla are available, Clonezilla live and Clonezilla server edition. Clonezilla live is suitable for single machine backup and restore. While Clonezilla server edition 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 server edition 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 of Clonezilla

* Free (GPL) Software.
* Filesystem supported: ext2, ext3, reiserfs, xfs, jfs of GNU/Linux, and FAT, NTFS of MS Windows. Therefore you can clone GNU/Linux or MS windows. 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.
* Multicast is supported in Clonezilla server edition, 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.
* Based on Partimage, ntfsclone and dd to clone 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.

Interesting. For all suggested Linux distributions (CloneZilla, gOS, Sabayon...) I am trying to boot them from an USB HDD. Knoppix, Puppy, Ubuntu, DSL... could already be put on USB key so I hope that there will be no much difficulties. The difficult work is to multiboot all of them on the same USB HDD (usually due to namespace collision).

Edit:
Well, after few experimentations there is no easy way to use grub4dos kernel/initrd method for those distributions. They are all issued from same type (e.g. Ubuntu) and use same files naming convention (livecd.squashfs...), same directories naming (/boot, /.disks...). The change this it would be necessary to change the script inside the initrd.gz which is of course not portable and easy.

So the only easy solution I found is to install each of them to a separate logical partition (ext3). You can use a common swap partition. Other advantages: data are persistent, and upgrade should be easier.
