Clonezilla是一个很好的系统克隆工具,它基于Partimage,吸取了Norton Ghost和Partition Image的优点。即不仅支持对整个系统进行克隆,而且也可以克隆单个的分区,这种灵活性可能更能适应备份者的需要。支持GNU/Linux的文件系统 ext2、ext3、reiserfs、xfs、jfs和Windows的FAT、FAT32、NTFS文件系统。Clonezilla支持使用 PXEBoot来进行Multicast克隆。这对于需要克隆大量系统的用户极为有用。开源软件!

Clonezilla 比起Ghost For Linux(简称G4L)有一个很显著的优势就是Clonezilla支持的文件系统格式比G4L多以外Clonezilla只备份数据,而G4L却将整 个分区都备份了(即包含空数据),所以G4L将比Clonezilla占用更多的用于存放备份镜像的空间。

* 不同於Partimage或是ntfsclone只能处理分割区，Clonezilla包含其他程式的撰写与整合，因此可以备份与复製分割区或是整颗硬碟 不同于Partimage或是ntfsclone只能处理分割区，Clonezilla包含其他程式的撰写与整合，因此可以备份与复制分割区或是整颗硬碟

* 不同於G4U或是G4L ，Clonezilla环境中，支援的档案系统(ext2, ext3, reiserfs, xfs, jfs, fat, ntfs)，只备份有存资料的硬碟空间，因此可以节省备份时间与硬碟空间。不同于G4U或是G4L ，Clonezilla环境中，支援的档案系统(ext2, ext3, reiserfs, xfs, jfs, fat, ntfs)，只备份有存资料的硬碟空间，因此可以节省备份时间与硬碟空间。 其他不支援的档案系统Clonezilla採用dd的方式处理。其他不支援的档案系统Clonezilla采用dd的方式处理。

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 suitalbe 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.

Changelog

Now the version number is synced. The same version number means same programs except the newer kernel and ntfs-3g are used in “-nk” files.

Some new features and bugs fixed:

- Based on Clonezilla 2.2.1-5, partimage 0.6.6 and Debian 4.0r1. For -nk version, kernel 2.6.21-2 and ntfs-3g 1.913 are used. Otherwise kernel 2.6.18 and ntfs-3g 20061031 is used.

- A TUI network config program ocs-live-netcfg was added.

- “No network” option was removed in the boot menu, since now the network setup is done when it’s necessary (like sshfs, nfs…).

- cciss device (Ex. Compaq’s SMART Array Controllers) is supported.

- Symbolic image file (Ex. hda1.aa is a link file) is supported.

- Two more options were added for ocs-sr: -o0 & -o1 (=-o before), which allows us to run programs in $OCS_PRERUN_DIR and $OCS_POSTRUN_DIR.

- Package pcmciautils, ncpfs, Packages dvd+rw-tools and udftools were added.

- Bug fixed: swap partition in lvm was not parsed correctly in ocs-onthefly.

- Bug fixed: nfs-common should be installed so that lockd can work.

- Bug fixed: A error when mounting samba server as clonezilla home was fixed.

- 1.0.5-7

- Based on DRBL 1.8.0-15 and Clonezilla 2.2.1-5.
