Now, losing data is something that could always happen by accident. That possibility is always there, no matter how careful someone is. Therefore, you need to keep multiple copies of data that matters. If you do that, then, even if someone decided to delete your data intentionally, it wouldn't hurt you that much, because you'd have other copies of it.
