我可以在哪里找到想要备份的文件？

个人文件(文档、音乐、照片和视频)

These are usually stored in your home folder (/home/your_name). They could be in subfolders such as Desktop, Documents, Pictures, Music and Videos.

If your backup medium has sufficient space (if it is an external hard disk, for example), consider backing up the entire Home folder. You can find out how much disk space your Home folder takes up by using the Disk Usage Analyzer.

隐藏文件

Any file or folder name that starts with a period (.) is hidden by default. To view hidden files, press the menu button in the top-right corner of the window of Files and press Show Hidden Files, or press Ctrl+H. You can copy these to a backup location like any other file.

个人设置(桌面首选项、主题和软件设置)

绝大部分软件的设置信息都以隐藏文件的形式将存储在您的主文件夹中(请参阅上面的隐藏文件信息)。

Most of your application settings will be stored in the hidden folders .config and .local in your Home folder.

系统设置

Settings for important parts of the system are not stored in your Home folder. There are a number of locations that they could be stored, but most are stored in the /etc folder. In general, you will not need to back up these files on a home computer. If you are running a server, however, you should back up the files for the services that it is running.
