Backing up your system using Time Machine
After you’ve installed Leopard, connect an external drive to your computer and use
Time Machine to make an up-to-date copy of everything on your computer.
Restoring your System
If you need to install Leopard again and you’ve created a Time Machine backup, use the
Restore Utility to restore everything on your computer to its previous condition.
Step 1: Insert the Mac OS X Install disc
Double-click the Install Mac OS X icon, and then click Restart. The installer opens
automatically when your computer restarts.
Step 2: Choose Restore System From Backup
Choose Restore System From Backup from the Utilities menu, and then click Continue
on the screen that appears.
Step 3: Select a backup source
Select the volume that contains the Time Machine backup you want to restore, and
then click Continue.
After you restore your system, your computer restarts using the volume on which you
restored your settings and data.
WARNING: Restoring your system erases all the contents of the volume you select.
