You said, you'd be willing to spend a little money on software to back up your files, right? Well, go out and spend the money on a burner, they've really come down in price. You don't even have to get a super fast spiffy one. Just get something reasonable, so you can back up your data. And then feel free to use any software you feel comfortable using. Trust me, backing up your data will really easy your mind, and it also can be used later on.
