I don't understand why you think I wont be able to access my data anytime? Dropbox synchronises the files so you have a local copy on each of your Dropbox hosts. So if Dropbox is offline, or you get disconnected from the Internet, you can still access them... Worse case scenario is something causes the file to get deleted and that propagates to all of the other hosts and deletes their local copies. But yes, I have backups so that isn't a problem.
