UCloner (原名 Ubuntu-cloner ) 是针对 Ubuntu编写的一个系统备份、恢复、克隆工具，使用UCloner可以将 ubuntu 系统备份为 squashfs 映像文件，也可从映像文件中恢复系统。具体方法如下：
备份：
UCloner 备份时可以使用图形界面或命令行，这里介绍图形界面，下载UCloner后解压，双击UCloner_CN文件，要求管理员密码。
备份前用清理工具先清理缓存和无效的配置相关文件，备份时软件会首先剔除一些常用的挂载点文件夹，还可以手动增加需要排除的文件夹，建议将常用的比如说存放电影，文档的文件夹排除，（或者将这些文件夹单独存放到移动硬盘里进行备份）这里由软件自动选取的文件或文件夹是不可以取消的。比如说我手动排除了用户文件夹里的软件，文档等文件夹，但是没有排除各种软件的配置相关文件夹（就是文件夹名前有“.”的，在用户文件夹里按Ctrl+h就可以看到），这样恢复时软件设置仍然不变，而文档存到移动硬盘里备份使用时也更方便些。
全部选定后可以用“估算体积”功能先估算squashfs文件大小，点击开始备份，我遇到的一个问题是squashfs文件体积会膨胀，当前不知原因，我估算体积位23.3G但实际备份达到了54.5G，大概半个小时时间，看个人的情况。
恢复：
使用UCloner必须要将备份文件放到另一块硬盘里，一般使用移动硬盘，然后是一个Live CD或usb启动盘，最好是与源系统同版本的，比如ubuntu10.04.2 64位版，否则根据软件说明的会出现不可知问题。将UCloner放到U盘中，由u盘启动，使用图形界面，各种参数介绍非常详细。

Grub2 will be installed to /dev/sda
