I have seen a lot of posts on different forums about save issues (Including loss of progression), Until these issues with save files have been fixed I recommend anyone on PS5 that use PS+ cloud backup go to Settings > Saved Data and Game/App Settings > Saved Data (PS5) > Sync Saved Data > Auto-Sync Saved Data once the lists loads up find Jedi Survivor in the list and turn off the sync function for the game. What this does is prevent the PS5 from automatically making a backup of the save file to the cloud.
Why turn this off? Two reasons
1.) If you loose progression on a save file, That loss of progression gets saved and uploaded to the cloud you no longer have a safe backup from the cloud to revert back to.
2.) If you crash and your save file becomes corrupted, That corrupted save gets uploaded to the cloud you no longer have a safe backup from the cloud to revert back to.
Both of these issues I have seen many people posting about on various forums.
Just note that you will have to manually make a backup of your save file occasionally which you can do by highlighting the game tile on the home screen pressing the options button and selecting Upload/Download Saved Data then select the Upload option. I am 35 hours into the game and my routine when I am ready to quit the game is go find a meditation spot, save the game, quit to the title screen, close the game and then manually upload the save. I have not had any issues with my save file or loss of progress, I will not guarantee that this is a full proof method to never running into a save file issue but it can help!
