I'd like to install a new hard drive into my Playstation 3. For that purpose, I want to back up as much as I can to get it onto the new hard drive again. While I've already copied all my saves, I'd like to know if I can also save the content of my message box (recieved and sent messages). I plan on using the backup utility to copy a backup onto the new hard drive, but I'm also saving some stuff manually.
I know there is a question here called What data does the PS3's backup utility preserve?, but unfortunately that question focuses on game saves with no mention of messages, and the accepted answer that says "everything gets saved" appears to be inaccurate.
I'd like to know whether the PS3's backup utility saves my received and sent messages, or if there is another way to save them to an external device to restore them on the new hard drive.
