For a full system backup, you can use Nandroid. But this tool is a bit advanced. It requires rooting the phone, and some other tweaks. Basically, this is very much used by people who install alternative ROMs. However, after backing up with Nandroid, you still need to backup the SDCard.
Using cp to copy the /data folder could maybe work to a certain extent, but I wouldn't recommend that because it could break if you restore after having upgraded some apps or for some other reason.
A simple backup of the SDCard (no need for adb, just plug with USB and copy) will normally contain your pictures and other files. But the contacts are stored in internal memory, somewhere under /data.
You can certainly find some apps on the market that are dedicated to backup. Don't skip this.
That said, the Android framework does provide backup to cloud storage, but this requires applications to support it explicitly and I am not sure that many apps do.

对于完整的系统备份，您可以使用 Nandroid。但这个工具有点先进。它需要对手机进行root，并进行一些其他调整。基本上，安装替代 ROM 的人经常使用它。不过，用Nandroid备份后，还需要备份SDCard。
使用 cp 复制 /data 文件夹可能在一定程度上有效，但我不建议这样做，因为如果您在升级某些应用程序后或由于其他原因进行恢复，它可能会中断。
SDCard 的简单备份（不需要 adb，只需插入 USB 并复制）通常会包含您的图片和其他文件。但联系人存储在内部存储器中，位于 /data 下的某个位置。
您当然可以在市场上找到一些专用于备份的应用程序。不要跳过这个。
也就是说，Android 框架确实提供了备份到云存储，但是这个要求应用程序明确支持它，我不确定许多应用程序是否这样做。
