) Time Machine, is software that comes with leopard (10.5), that allows you to recover datafrom a previous backup date. All the files are viewed through finder in the time machine software. What really goes down behind all this is a backup of all your files that are categorized as you do in finder, to your external drive. Every time you backup your machine it creates a new dated folder in the backups folder on your external drive. Time machine uses a snazzy interface instead of going through folders.
