That is a good point. I have only lost one dvd through wear and tear over the years and that was because I dropped a hammer on it. :duh:Is your reason for backing up, wear and tear on the physical disc by kids/family? What I've done for my Pixar films is that the blu-rays stay in my theater and the kids get to play with the DVDs. By the time they ruin the DVD version, the cost of a replacement DVD is so cheap its easier/cheaper to replace it than the storage, read/write wear and tear on my NAS. It's been years and they haven't ruined a DVD yet.
