Until I read this piece, I thought of Leopard (OS X 10.5) mainly as eye candy, now I see that this Time Machine is a truly elegant way never to lose a file. Basically, you stick an extra hard disk into a USB drive and you get a back up of every file in your computer every hour and it is easy to scroll and find things. Amazing work, Apple!
“Appleinsider”:http://www.appleinsider.com/articles/07/10/12/road_to_mac_os_x_leopard_time_machine.html gives a great technical overview for geeks who know about hard links in Unix and how they cleverly use this to allow any incremental backup to look like the whole file system. It really relies on uses fast disk instead of slow tape for storage.
That plus a great user interface and wow!
