Back That Thing Up

Let me be an example to you all; back up your stuff. I know, I know, we all know it but few of us actually does it. A geek from the Geek Squad determined that my laptop will need to be wiped out and all its data will be lost unless I pay a few hundred bucks to retrieve the files. My last back up was done around 2-3 weeks ago and for the god in me, I have no idea if any of my recent pics are backed up. I have, of course, stored some on Flickr and I also have emailed my friends some of the picture that they are in, but the originals are all stored on my hard drive, everything sent out are altered in size. It sucks.
