ubuntu还原初始状态

Wouldn’t it be nice to be able to try a new version of Ubuntu while knowing you can return to the previous version if you don’t like it? We’ll show you a tool that allows you to take a snapshot of your system at any time.

能够尝试新版本的Ubuntu，同时又知道如果您不喜欢可以返回以前的版本，这不是很好吗？ 我们将向您展示一个工具，该工具可让您随时拍摄系统快照。

TimeShift is a free tool that is similar to the System Restore feature in Windows. It allows you to initially take a snapshot of your system and then to take incremental snapshots at regular intervals. TimeShift protects only system files and settings, not user files such as documents, pictures, and music. You can use a tool like Back In Time to backup your user files.

TimeShift是一个免费工具，类似于Windows中的“系统还原”功能。 它使您可以首先对系统进行快照，然后定期进行增量快照。 TimeShift仅保护系统文件和设置，不保护用户文件，例如文档，图片和音乐。 您可以使用“ 时光倒流”之类的工具来备份用户文件。

Recently, we showed you how to back up your applications and PPAs using a tool called Aptik, which is included in the same PPA as TimeShift. First, press Ctrl + Alt + T to open a Terminal window. If you haven’t installed Aptik, type the following two commands (separately) at the prompt, pressing Enter after each command, to add the PPA and update it. For more information, see our article about Aptik. Note: you may have to remove the -y switch to get it to work.

最近，我们向您展示了如何使用称为Aptik的工具备份应用程序和PPA，该工具与TimeShift包含在同一PPA中。 首先，按Ctrl + Alt + T打开“终端”窗口。 如果尚未安装Aptik，请在提示符下分别键入以下两个命令，在每个命令后按Enter，以添加PPA并更新它。 有关更多信息，请参见我们有关Aptik的文章。 注意：您可能必须删除-y开关才能使其正常工作。

sudo apt-add-repository -y ppa:teejee2008/ppa
 
sudo apt-get update

sudo apt-add-repository -y ppa:teejee2008/ppa
 
sudo apt-get update

If you have installed Aptik, you are ready to install TimeShift and do not need to enter the previous commands. Type the follow
