> good daily backup

Therein lies the rub. I've consulted/worked at a crapton of companies and organizations over the years. The vast majority had minimal backup solutions or none at all. Reliable backup solutions are expensive and not coincidentally, upper management at these companies just wouldn't pay for it. I can't tell you how many times I was told something along the lines of "Why are we spending money on IT when the IT dept. doesn't make the company money?" Management usually would just hang the IT dept. out to dry anytime something like this happens so there's seldom any real repercussions for the actual decision makers that cause the mess to begin with. Wash, rinse, repeat. And this is the sad and pathetic reason why something as strange and convoluted as ransomware schemes are so successful.
