I once got a call from a buddy of mine. In a panicky voice he said, “My computer crashed and it won’t reboot! What do I do?” I replied, “Boot from your backup.” His answer: “I don’t have a backup.”
What we can do with computers is pretty amazing. But your work is being saved on aluminum and metal coated glass discs that are whirling at thousands of times per minute. Not much room for error. And with all that stuff spinning away, stuff can, and will, go wrong.
All your work exists as ones and zeros. What are you doing to protect it?
