How can I make a backup for my entire project?

I just want to know how to make a Back-up in my project so in case i want to open it in another PC or my actual one breaks down i wont lose my information.

What i did is i copied the whole project folder into my USB that could do the thing? It might sound like a ridicolous question but i don’t know anything about this kind of things.

Project folder is all you need.
