My highly redundant yet simple backup strategy

Over the years, I have collected about 170,000 photos, and that total is climbing every week.  While they aren't all winners, they are all mine and I want to keep them around forever.  So how do I make sure they will be here for me at some future date?  Well, that's what I share here today - plus I ask for your feedback to make my process better.  Read on and let me know your thoughts!
