Ghost很流行,很多人在用,用它来备份微软的系统还是挺不错的,但对于非微软系统,就不那么好了。

主要的问题体现在兼容性方面,你可以用它来备份Mac OS X的日志式HFS+分区,但还原时它就不再是原来的那个日志式HFS+分区了,因为Ghost只支持HFS分区(HFS+分区的上一个版本)。另外它对Linux的支持也不是很好,因为较新版本的Linux往往默认使用Ext4分区,Ghost并不支持Ext4,即使你在安装Linux将分区格式改成Ext3,Ghost还是不能对它进行克隆,因为较新版本的Linux往往使用大于4KB簇的Ext3分区,而Ghost并不支持大于4KB簇的Ext3分区。所以使用Ghost来备份Linux,即使能备份/还原,也不是很好。

现在,有一种开源软件做得比Ghost更好,那就是Clonezilla。它基于Partclone软件,有基于Debian和Ubuntu发行版的LiveCD,它可以支持很多(文件)系统的备份/恢复,而且你还可以用DRBL来进行网络克隆,Ghost有的功能它都有了,Ghost没有的功能它也有。

Clonezilla支持的特性:

Free (GPL) Software.

Filesystem supported: (1) ext2, ext3, ext4, reiserfs, reiser4, xfs, jfs of GNU/Linux, (2) FAT, NTFS of MS Windows, (3)HFS+ of Mac OS, (4) UFS of
FreeBSD, NetBSD, and OpenBSD, and (5) VMFS of VMWare ESX. Therefore you can clone GNU/Linux, MS windows, Intel-based Mac OS, and FreeBSD, NetBSD, and OpenBSD, no matter it's 32-bit (x86) or 64-bit (x86-64)
OS. 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.

Grub (version 1 and version 2) is supported.

Multicast is supported in Clonezilla SE, 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 Partclone (default), Partimage (optional), ntfsclone (optional), or dd to image or clone a 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.
