I do keep a back up of things, but the back up is on S3 because that is the most stable storage option available to me. Everything else is the risky copy.

>Do you control Amazon? No? Then you're not the captain

This is textbook NIH syndrome. Rather than looking at the relative probabilities you look at something from an ideological perspective. Your argument isn't "Its safer with me" its "I want to be in control of it" This attitude is generally harmful. Think about your money. Are you in control of the bank? no right, but you still keep your money there instead of in a shoe box under your bed. Why? Because the bank is better at protecting your money than you are. They have big heavy metal doors and men with guns to move it from place to place. Amazon is like a bank for your data.
