So I have a Macbook (13" 2008 model) and iMac (20" 2006 Intel Core Duo model) and just purchased Snow Leopard to upgrade the machines. Given my preference for a clean install, I would obviously need to back up my data. However, my back up external drive broke a little while back and trying to get another one (I'd need 1 TB) just isn't feasible financially at the moment. So with the option of backing up the files to blank Blu Ray discs being a cheaper option, would that be possible? Or does Apple not supporting Blu Ray affect this? Or does it only affect official motion picture Blu Ray discs? Was just wondering how feasible this would be. Thanks!
