Now, if you want to restore all of your saved game info, connect your USB hard drive that you used to do the back up on.

Go to the 'Settings' XMB menu, select 'System Settings' and then go to 'Backup Utility'

Select 'Restore' and then select the USB device that should have your backed up data on it.

You should only have one backup to choose from.

The PS3 will reformat the hard drive and copy the backup, this can take up to 2 hours.

Congrats, now you have a PS3 with a HUGE amount of space.
