Our enormous appetite for data has bred an equally huge existential dependence on that data being available. It's not just the big names on the Fortune 1000 who can't live without info, either. Businesses as small as florist shops and veterinary clinics can't get by without their delivery schedules and patient records -- all of which are stored digitally.
That's progress: Digital data allows us to work more productively with less overall waste. In the early part of the last century, you could've said the same thing about electric power or the telephone. They solved all kinds of problems for humanity -- yet look at the chaos that ensues when they suddenly become unavailable in ways no one considered.
Stage your own data outage
Any time you develop a heavy dependence on anything, it's important to take a step back and imagine what you'd do without it. Unless "quit immediately and move to Mexico" is your answer, staging a tabletop data loss fire drill is a good idea.
