The problems mentioned in this thread still exist, but you can use version control to backup your projects. Check in the <your workspace>/games/<your-game> directories. You can exclude the behavior-hx subdirectory, that one contains code generated from the design mode snippets. You may also want to exclude the scene thumbnails: <your workspace>/games/<your-game>/scenes/*.png
Besides that, you don't need to check in the folders under <your-workspace>/games-generated, those are also, as the name suggests, generated when you test your games.
