Norton 360. Windows 7. Personal home use. Currently I am trying to solve missing external hard drive space via Norton Community Forum, as I can't back-up. Consequently I have been looking at online storage as an alternative. Apparently I can get 25 GB storage for $80, but my external hard drive shows that I am using almost 500 GB ... and my wife has another computer. Could you tell me, in say graduations of 100 GB, how much I would have to pay for online storage above 25 GB.
