If you want to do a more specific backup, or learn how to place downloaded savefiles on your PlayStation 3, check Method 2 below.
Navigate to Settings -> System Settings
Scroll down and select Backup Utility and choose Backup.
You will see two warnings, one will tell you that you can’t backup Trophies, the other one is a regular affirmation form. Confirm both times.
Next, you’ll be prompted for the destination. You can use any flash drive or external hard disk, just make sure you’ve got enough space available.
Wait for the process to finish, and you’re done. Once you’ve put the backup somewhere safe, you can sleep soundly.
Note: If you want to restore the backup, go back to Settings -> System Settings -> Backup Utility and select “restore”. Once you’ve told your PlayStation where to look, your files will magically fall into place, but know that all the other files on the PlayStation 3 will be deleted!
