I'm sure you already know what I'm going to tell you: "Of course you need that backup_label file. How could you even think that you don't need that backup_label file?" Well, you're right. That is what I'm going to say. But do you know why you need that backup_label file? If you were to remove that backup_label file (or fail to create in the first place, in cases where that is your responsibility), what exactly is the bad thing that would happen to you?
