He clearly cared about his data, don’t equate this man to the people who don’t really think about it and don’t actually back their stuff up (and come crying to everyone when their 10 year old disk dies)
People like to say to use the 3-2-1 backup strategy, which is really good advice, but it does NOT scale, trust me. I guarantee you I have more disposable income than this journalist (I assume that because journalists make shit money), and when I looked into a 3-2-1 solution with my meager 60TB of data, the cost starts to become astronomical (and frankly unaffordable) for individuals.
