Time Machine est un logiciel propriétaire de sauvegarde incrémentale automatique et de restauration d'Apple, intégré à la version 10.5 (Leopard) de Mac OS X sortie le 26 octobre 2007, nécessitant un disque dur externe.

Apple's Time Machine is a great feature in their OS, and Linux has almost all of the required technology already built in to recreate it. This is a simple GUI to make it easy to use.
