Clonezilla是一個很好的系統克隆工具,它基于Partimage,吸取了Norton Ghost和Partition Image的優點。即不僅支持對整個系統進行克隆,而且也可以克隆單個的分區,這種靈活性可能更能適應備份者的需要。支持GNU/Linux的文件系統 ext2、ext3、reiserfs、xfs、jfs和Windows的FAT、FAT32、NTFS文件系統。Clonezilla支持使用 PXEBoot來進行Multicast克隆。這對于需要克隆大量系統的用戶極為有用。開源軟件!

Clonezilla 比起Ghost For Linux(簡稱G4L)有一個很顯著的優勢就是Clonezilla支持的文件系統格式比G4L多以外Clonezilla只備份數據,而G4L卻將整 個分區都備份了(即包含空數據),所以G4L將比Clonezilla占用更多的用于存放備份鏡像的空間。

* 不同於Partimage或是ntfsclone只能處理分割區，Clonezilla包含其他程式的撰寫與整合，因此可以備份與復製分割區或是整顆硬碟 不同于Partimage或是ntfsclone只能處理分割區，Clonezilla包含其他程式的撰寫與整合，因此可以備份與復制分割區或是整顆硬碟

* 不同於G4U或是G4L ，Clonezilla環境中，支援的檔案系統(ext2, ext3, reiserfs, xfs, jfs, fat, ntfs)，只備份有存資料的硬碟空間，因此可以節省備份時間與硬碟空間。不同于G4U或是G4L ，Clonezilla環境中，支援的檔案系統(ext2, ext3, reiserfs, xfs, jfs, fat, ntfs)，只備份有存資料的硬碟空間，因此可以節省備份時間與硬碟空間。 其他不支援的檔案系統Clonezilla採用dd的方式處理。其他不支援的檔案系統Clonezilla采用dd的方式處理。

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.
