I'm thinking of setting up a home server for back ups and file storage and sharing of my home network. Right now I back up each individual computer to my 2nd hard drive on my desktop. I would like a more efficient way of doing this and automated preferably. Werther I build or out of a box, I would like some input on how I should go about this. I've seen HP's version of the home server back up which looks pretty simple and exactly what I'm looking for. What are the difference's between the home sever OS and server 2008 OS?
