• Save data on a shared PS5 shows whose save is whose. Each save is labelled with its
  owner's name instead of a number, and the screen starts on the user who is signed in at the
  console; "Whose saves" switches to another user or to everyone. Back up all and Restore all
  act on the saves shown. A backup saved on your computer is named after the game and the user
  (PPSA01234-Alice.zip).
• USB backups are kept per user. Backups to a USB drive on the console now go into a folder
  per user (<game>/<name>-<user id>/<date>/). Before, every user's backups of a game shared one
  folder, so on a shared console "Restore all from USB" could put one user's latest backup into
  another user's save. Backups made before this update are still used when only one user on the
  console has a save of that game.
