You know all those game saves that you have on your home console? Should that console go missing or get damaged, all of your season data in Madden and all your progress in Call of Duty can be lost. That’s not good. It’s a scary thought for most gamers, but we all have to realize that it’s a very real possibility.
The good news is that Sony is on your side. If you get software update 4.25 on your PlayStation 3, Sony is going to offer you an upgraded 1GB of online game save storage. What this means is that, if you are a PlayStation Plus member, you can have your game saves backed up to the cloud. Should anything happen to your PS3 or should you move to another PS3 console, all of your game saves are there for you.
What you have to do is to go the PlayStation Store on your PS3, install software update 4.25, and then go to Game column in the XMB. Under that, you’ll find the Saved Data Utility as usual, but it will also give you access to your online storage folder. You can fiddle with the settings, but it’s recommended that you get all of your game saves (as long as they’re compatible) to upload automatically. One gigabyte isn’t as good as the 48GB you get when you buy a SGS3, but game save files are so small anyway.
Just as an aside, all you Xbox 360 people have a similar function on your consoles. Microsoft has cloud storage for saved games too.[Source]
