Hacking Help with Save files on PS4

[elm]

I'm not sure why this keeps happening?

I haven't played with my PS4 in over a month and when I wanted to play GTAV today, but my save data got erased, its just disappeared. So luckily I copied it on a USB drive through Al Azif host site and now I can't figure out how to extract it back on my Ps4??

Thanks

You can try to restore the data on the USB drive, in the future it is best to backup your SG and DB with Stooged DB and SG tool occasionally.

Ok thanks, I'm not sure what SG and DB is, but I'll look it up.
Any clue on how to "Restore" my save files that I have now from the USB drive? Thanks
