You&#x27;re entirely free to play fast and loose with your customers data.<p>It is interesting that even today there are still people arguing against having back-ups because &#x27;the cloud&#x27;, you&#x27;d think that we ITers learn from our mistakes but for some this has to be personal experience before the lessons are learned. Good luck if and when it happens to you, please re-read your comments here at that time. There isn&#x27;t an IT person that I know that has not been saved by a back-up at some point in their career, the fact that you are lucky so far is not a reason to think you are exempt.<p>And no, nobody is advocating storing your money in a mattress because you &#x27;don&#x27;t trust the banks&#x27;, the point is that you can keep a copy of your critical data for <i>very little money</i> to safeguard against an eventuality that seems to hit the IT world with alarming regularity, even if they use &#x27;the cloud&#x27;. Fuck-ups, hacks, disgruntled employees and failures all happen, every day.
