Under Management you'll find the Health Monitor.
In there under "Small Business Server Alerts" there are some Events listed, that throw an alert.
Also the Windows Small Business Server Backup failed Event ID5634".
Copy and paste it as new Event.
Perform the following changes to the new Event:
Event ID: 5633 (Backup successfull)
Type: Information and Success (seems like Information alone is enough, see Picture)
Mail should be send at status "Ok":
Edit the Message, so that the message is something like "Backup successfull!" at status Ok:
That's all folks.
