Dropbox Anyone?

I'll confess right up front that I'm terrible about backing up my documents. I was using a memory stick for a while but only remembered to do it once a month or so. Then there was the emailing-novel-to-myself phase. I remembered to do that about twice a month. I checked out some of the online services that you pay for (mozy, etc), but I'm so cheap I just can't stand paying for things if I don't have to. (Actually, I think they offer 2 gigs free now.)

But still, I thought there must be another way.

I just discovered dropbox. I'm not terribly tech-saavy, so this may be old news, but I'll share anyway. You go to dropbox, download it, and a folder will appear on your computer. Anything you put in this folder can be accessed from any computer connected to the internet.

They market dropbox as a way to organize your files across multiple computers, phones, etc, but all of the files you drop in your dropbox folder are also instantly uploaded to the internet. So, if your computer breaks and your phone bursts into flames, you still have access to your files via "cloud computing."

Now, when I sit down to write, I open Chapter 18 from the dropbox folder and work on it. When I hit "save," the doc is saved not only on my computer but also on the internet. I don't have to remember to back up. I don't have to do anything special. I'm loving it.

So, what do you use to back up your writing and how do you like it? Ever tried dropbox? Have concerns I haven't thought about?
