While my backup "game" was likely more detailed than 99.99% of the world, I stepped it up again this week. I added a NAS to my gadgets. As I discover and prove I am comfortable with what the NAS can do, I will be able to rid/repurpose a few gadgets.
With proper encryption, you can leave your data on your front porch or even hand out USB sticks to your local hacker, and it will remain safe (maybe not against a group with national type resources and time, but those are not my concern at all). I doubt the IRS investigates or would want to take on an entity like Google by making a statement prohibiting using gDrive for storage. Few, if any, hacking groups are after the data you or I have, since what you have, even if it was 5000 clients, is worth their time. For me, I keep no card information, so hacking me would be a waste of time too. My concern is being able to get back to work in as short of time possible.
