Ya, about 5 minutes ago, I accidently deleted the save data thinking I'd already copied it onto my USB. It was a duping. Not quite annoyed but more disappointed.
I'm not expecting any back-up if anyone know's or if there is a way to retrieve lost save data, please tell me.
Also, if you have an additional account on your PS3 you can copy your save game to another profile... You can't load it on the other profile, but it can be a backup.
For what it's worth... If you wanna friend me I can give ya a leg up by sending you a car... Anything in the Premium Dealer that costs less that 5,000,000...
I lost all my data the 1st time I hit LVL 21, wasn't all bad though...it took about 5 days to get back to where I was AND I didn't spend money on junk cars that I found I didn't like.
