backup PS3 games without jailbreaking

i have a a ps3 160 GB, and about 40 games, i have spent alot on them and some of the titles are even purchased twice because of damage. so i was wondering if there is any way of making a backup DVD of my games (maybe using a blue-ray burner) or just copy the whole game to the HDD (there are ISO games available on torrentz which can be downloaded). please tell me if any of the two solutions will work

also please Don't tell me that "this is illegal" as this is for personal use, i am aware of what i am doing and ready to face the consequences.

No, you could only buy digital copies or you can store your games in such a way they don't become damaged.
