可以替代Ghost的系统备份/恢复利器Clonezilla

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.
