* how to back it all up

Buy things in pairs. Use one to make a physical copy of the first. Works well for me. I'd make backups of myself, but the neighbors would complain about crowds hanging around my house? Imagine the home-delivery beer tabs?

* how to secure it

Make 'em small enough to swallow. Bad guys surveilling you from across the street? Slap that drive on a ham sandwich. Hmmm! Crunchy! Next time do it with peanut butter and jelly.

And that's just part of the goodness of tech advancements. Try securing a 3-1/2 floppy in a ham sandwich.
