I ever wonder what will happen if my files in my pc gets corrupted. Heard a few whines from friends about their files being corrupted and was so worried how to get back those important files back. Never experienced such thing yet and I'm hoping I wouldn't be experiencing that dilemma. So I guess online backup is really a necessity for computer users. My brother also had mentioned that to me once. And perhaps he knows how to use it then. Will be encouraging him to help me use it too.
