It's a normal human tendency to stay optimistic and believe that you are immune from disaster. We say, "that'll happen to other people, I'll hope for the best and focus on my day-to-day activities."
Imagine if a disaster hit and you sustained serious downtime, got hacked, or lost data your customers needed. The results would be disastrous for your reputation and could mean the end of your business. You'd be kicking yourself for not preparing.
But just like a teenager learning to drive, sometimes getting in an accident helps you learn to operate more safely. The good news is that there are practical things you can do to reduce your risks of software disaster.
