For a really long time I used to back up all of my stuff on an external hard drive, and then like a lazy a$$ totally got out of the habit.

Then my MAC crashed and I thought life as I knew it was over.

I'd been backing up on dropbox for a really long time for professional use, but I'd never saved my writing on there.

After that I made sure I ONLY wrote out of the files that I had saved in dropbox.

If you're not using it you should be. It's amazing and you can access it on every mobile device known to man.
