You only need this if you want to redo/replace your PS4's HDD for some reason but you don't want to go to the trouble of downloading everything again.

You need to jailbreak the PS4 and then connect with FTP (Filezilla is perfect for this).

Then you just go to the /user/app/CUSAxxxxx folder for the game you want to back up and copy out the app.pkg to your PC. Also check the /user/patch/CUSAxxxxx folder if you want to keep the update pkgs.
