Much of the discussions surrounding the most recent Apple software upgrade (OS X 10.7) refers to the fact that Apple are no longer shipping their product on physical media. Well, that's not strictly true - they will be producing a $70 USB version sometime in August. Most people will access the software after having purchased it from the App Store and downloading more than 3.5 GB of data. This is great in that it makes for a smaller environmental footprint as there'll be less packaging and less fuel-related costs but it does have it's downsides in that you can't reformat or install without an Internet connection.
Never fear, as there is a way to make a backup copy of the software without having to upgrade from OSX 10.6 (Snow Leopard) first. In the video below I show you how to make a bootable backup up copy of OSX Lion via DVD. It's quite easy. Click through to YouTube for the HD video.
