How do you back up your files?

I have Carbonite on this computer. ... So, you can call up these files there easily, but not vice versa. Things that I put in my office computer, I have to email to myself if I want to work on them here.

Well, I make the folder that is the book that I'm going to submit, to see if I can get it published. And in order to have arrived at that, I've printed things out and done my gungy little no-tech, on-the-floor, dogs-walking-over-it, leaves-falling-on-it kind of procedure that I was shame-facedly describing to you moments ago. And so, I end up with a paper copy in a file, at least one. And also at that point, I'm usually trying to bribe a couple of friends in to reading it before I send it off. So, I'm either emailing them, or handing them a copy.

I have a Dropbox account and I have a 2 TB amazingly small little white brick— ... that backs up automatically.
