Can I play PS3 Saves from one PS3 on another?

Solution 1:

Some PlayStation 3 games have locked game-saves which means their game-saves are tied to the system itself. The result is that if you backup these files in a USB or an external HDD, you won't be able to use them in another system. (This is most likely done through encryption).

Here's a list of games with locked game-saves. As the list states, games without asterisks have files which are locked to the system.

However, there's a way to bring these locked game-save to another system. The PlayStation Plus service lets you upload these files to Sony's servers to be able to retrieve them in other systems. This service is not free.
