What Are Your Thoughts About Online Storage?

Nowadays, I’m beginning to think that hard drives are not reliable. I spend so much time doctoring my hard drives and one day it crashes and I lose all the information on it. I also can’t find a good recovery program to retrieve my files. Therefore, I need to start over.
I think about storing on two hard drives but it seems redundant. Then, the thought of storing online comes to mind. I wouldn’t mind spending some money on this kind of storage. The main issue seems to be PRIVACY. Could it be a way to crack down on piracy?
Anyone have any thoughts on this matter? Thanks in advance.
