I have a question... Are you sending people emails letting them know you have ALREADY deleted the backup, or are you giving them advanced warning that you WILL delete it in X days? Do you intend to remove the verbiage about "Unlimited online storage?" If something is legitimately unlimited then this policy makes no sense but as both you and I know truly unlimited anything is impossible, so why say it?
