Hopefully you'll never need to perform action but if you do the following steps will allow you to revert a save on your PSVita to automatically created back up. I personally had to do this when my save file for Final Fantasy X HD got corrupted. I lost about 30 minutes of play time but that was better than having to start all over again.
- First check to see if an automatic backup exists. They should be located at
ux0:/user/xx/savedata_backup. You can perform this step and the next two from VitaShell. - Create a backup of the existing backup file, these are located at
ux0:/user/savedata/xx/savedata/$TITLEID. Ensure to change out$TITLEIDwith the games actual title ID. - Next navigate to the games save directory -
ux0:/user/xx/savedata/$TITLEID(again remembering to change$TITLEIDto the games title ID). Go into thesce_sysdirectory and remove thesdslot.datandkeystonefiles. - Exit VitaShell.
- Start up the game and you should receive a message about the save file being corrupt and if you'd like to restore. Answer 'Yes' here.
