Personally I just rely on daily backup of my workstation and manually copied and compressed snapshots of the project when I feel significant progress has been made. I tried SVN once, but it wasn't very transparent what it was doing and didn't really enhance my workflow any.

Is all of your coding projects that you are working on by yourself? Or do you have to share code with other people?

All my personal projects are just me. When I contribute to open source projects I use whatever they use, which is usually git. At work, even though I am usually the only programmer on my programming projects, I use TFS because that's the company's process.
