The overall Success Notification is very definitely NOT checked. Our setup is stable enough but large enough that I don't need to add more emails to the over 300-500 I get nightly from a combined trio of backup solutions (one solution sends emails no matter what). As with any product, I don't need to know when the regular, everyday stuff works, I need to know the exceptions. And the current failure emails are great for that. But having to log completely on, especially when I'm away from my office, just to verify that a retry eventually worked, is a pain.
