SuperDuper runs on Intel and Power PC Macs, and is compatible with Time Machine under Leopard. Download and use it forever for free, or buy for US $27.95 to unlock scheduling and Smart Update. (Smart Update copies only the data that has changed since your last backup, enabling you to backup your hard drive in minutes instead of hours. Which means you’ll actually get into the habit of running the backup program every day. Which means you’ll never lose your work. Best $27.95 you’ll ever spend.)
We got SuperDuper! after the PowerBook Catastrophe of 2005 and it saved Elena’s data from annihilation just over a year later when the replacement hard drive failed.†
