Not unheard of, but usually your fault ("I didn't think I need a backup"), and easy to avoid once you've formed a habit. You're right that the safest option will be to have backups of your own, but at that point the cloud is only adding convenience for backing up your device for restoring, or for synchronizing files between cell and pc. To be sure you still have your data five years from now, you still need to do it yourself. I believe a lot of people understand the cloud to mean "I give you money, you make sure everything works and I don't have to get into the details".
