Things You'll Need
Instructions
Connect your PS3 console to the Internet using a wireless or Ethernet connection. Make sure your computer is on the same Internet connection, so the backup data files can be transferred over the network.
Download and install the Java PS3 Media Server program (see resources).
Turn on your PS3 console by holding the "Power" button for one second.
Find the PS3 Media Server program on your computer and double-click to run the program, which will automatically detect your PS3 console and establish a connection.
Scroll through the icons on the your PS3 main menu using your PS3 controller joystick until you find an icon labeled "PS3 Media Server." Press the "X" button your controller to select the icon.
Wait for the PS3 console to retrieve information from your computer's hard drive. Once the files have been synced between the computer and PS3, you can begin the transfer.
Press the "X" button on the file you want to create a backup file for. A panel on your right-hand side of the screen should appear. Scroll down to the "Copy" option and press the "X" button to select. This will make a duplicate copy of the computer file within your PS3 hard drive.
