Norton Ghost : Clonezilla

You're probably familiar with the popular proprietary commercial package Norton Ghost®, and its Open Source software 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 Open Source clone system (OCS) solution called Clonezilla with unicasting and multicasting! With DRBL and network boot enabled client computers, the only thing you have to prepare is a Clonezilla server. You do not even have to prepare a bootable CD or floppy with Partition Image for every client computer.

Clonezilla, based on DRBL, Partition Image, ntfsclone, and udpcast, allows you can massively clone many (40 plus!) computers simultaneously. Clonezilla saves and restores only used blocks in the harddisk. This increases the clone effiency. At the NCHC's Classroom C, Clonezilla was used to clone 41 computers simultaneously. It took about 50 minutes to clone a 5.6 GBytes system image to all 41 computers via unicasting and only about 10 minutes via multicasting!.

Feature

• 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 other file system, Clonezilla uses dd to dump the whole partition.
• LVM2 (LVM version 1 is not) under GNU/Linux is supported.
• Multicast is supported in PXEBoot Clonezilla, 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.
• If file system is supported (ext2, ext3, reiserfs, xfs, jfs, fat, ntfs), only used blocks in harddisk are saved and restored. This increase the clone efficiency. For unsupported file system, sector-to-sector copy is done by dd in Clonezilla.
• 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.
• A single machine clone system without installation, Clonezilla live, is also available.
