No, you can't store all of your 320 GB data on a cd/dvd.I recommend buying a Portable Hardrive to store all u need. They only cost about 70$-150$

no, buy an external drive and use it as your backup.

A regular DVD has a capacity of 4.7 gb, a dual layer is double that. So no, 320 gb of stuff won't fit on a 4.7 gb DVD, however your personal stuff may be only a few gbs (not your whole hard drive size) which you could save.

the answer is no it is not possible get a memory stick with usb and put all your stuff on that there only about 20.00
