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 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.
