Questions about cloud hosting for a solo dev

So basically I’m shopping around for the right version control software. Whether free/open-source like SVN, or paid like Plastic, I keep seeing references to cloud hosting, which pretty much always requires some kind of extra subscription.

As someone with a non-technical background, I don’t feel like I have a good grasp on whether or not cloud hosting is even something that I would benefit from as a solo developer. What are the pros and cons?

And even if it’s something I do need, is there a "free" way to go about it?

For example, would it be a valid workflow to install SVN for maintaining a local repository on my computer, and then just manually upload my current project version to GitHub periodically to serve as a sort of "offsite backup"?
