Sometimes folks don't have an answer or an opinion. In the future you might consider being patient...
Anyway, a cloned hard drive is the best protection. Norton Ghost has bailed me out on many occasions ( for a complete restore ) and you can pick up a hard drive fairly cheap.
For data only protection, you could set up all or most of your programs to save to a specific folder. You could then use Nero to create a data disk and select verify data to be certain that you have a good burn. I still don't trust dvd media for long term storage because its still a relatively new product.. . but thats just my opinion. Try this thread for drag to disk-
