Time Machine uses a unique interface that turns the rather boring task of backing up and restoring files into something that you may actually enjoy doing. And you may not even have to think too much about the “backing up” portion of the exercise—according to Apple, Leopard will automatically back up your files as you work.Source: Macworld
Out of the ten features previewed at WWDC this year, Time Machine was by far my favorite. There is third party software that will kinda do what Time Machine does. But nothing so seamless, but that is the Apple way.
Just get a very large (say terabyte) drive to be able to keep a nice sized backup on hand.
