Editor: Apple's Mac OS X Leopard (10.5) and beyond features Time Machine, an easy-to-use, automated local backup solution for Mac computer users. By connecting a second hard drive to your computer and configuring the System Preference, Time MachineĀ® performs an initial full backup of your hard drive and then performs Automatic Hourly incremental backups. Time MachineĀ® saves the hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for everything older than a month. We applaud Apple's commitment to this very important computer support function.
