I currently have a portable hard drive that stores copies of my photos, music, files, financial stuff, etc... and most of these things I don't need to refer to on a daily basis - I would probably look at them once every couple of months. So I was thinking of transferring some of the files that I do refer to more frequently to iCloud or some cloud storage but I'm a little concerned about the security of those files. None of them have my passwords, personal information, etc. For those of you who use cloud storage, what would you put online and what would you not?
