That's a shame, but at the same time you have to wonder who would store five years of photos using an online service and not have a single backup. Buy one or two cheap portable hard drives and do a monthly backup of all of your can't-live-without files to both drives every month. Store them in a safe place and don't use them for anything else. Problem averted.
Edit:
Or shit, at least have a copy on your computer.
