And  you are able to set daily/weekly/monthly automatic sync, thereby you won’t worry about forgetting to backup important data someday.

The first method is really, you just need to open command prompt and type the command above. Thus, here I'll show you the second method in detail and share files over a network. And you can still use it as a long-term data protection solution.
