Since you are not new to the scene and understand everything. let me help you out a little with what I do. Run HEN, hit PS button, go back into exploit and run the FTP. It will tell you what port it is listening on along with the ip of your PS4. Now go to your PC and run an FTP client like Filezilla and browse to
/user/home/profileID/savedata Copy your saves to wherever you want ie. strongbox, fort knox, desktop etc.
Take down these notes if you want to back up everything important:
Trophy locations:
user/home/XXXXXXXX/trophy folder and the user/trophy folder
DB locations:
/system_data/priv/mms/app.db and /system_data/priv/mms/addcont.db
Save game locations:
/user/home/XXXXXXXX/savedata folder, /user/home/XXXXXXXX/savedata_meta/ and system_data/savedata/XXXXXXXX/db/user/savedata.db
Game PKG location:
user/app/CUSAXXXXX/app.pkg
Update PKG location:
user/patch/CUSAXXXXX/patch.pkg
DLC content location:
in the ADDCONT folder per game.
Do not try to backup using the standard PS4 menu under settings. That only works if your PS4 is not jailbroken.
