Apple Time Capsule - 3 TB

Automatic backup with Time Machine.
Time Capsule works automatically with Time Machine in OS X Leopard or later to create the perfect no-hassle backup solution. There are no cables, and you can back up all the computers in your home to a central location. New technologies in Time Capsule and refinements to Time Machine make backing up to Time Capsule using Snow Leopard up to 75 percent faster than before.

Server-grade storage.
The massive 2TB or 3TB server-grade hard drive gives you all the capacity and safety you need for backing up all your Mac computers.
