Which do you think is safer, online or offline? For me, I don't think my computer is safer. Viruses, software or hardware problems may damage my important data one day. I think the online storage is safer, perhaps. Of course, you shouldn't use the online services to store your private information, such as credit card number, bank password. Of course, using the online storage service as a backup tool is much better. In this way, even thought your computer is lost, you can find it from the Internet.
