With a sql agent you don't backup everything of your sharepoint installation. 
The only correct thing to do from a networker point of view is to use nmm.

Correct, nmm is far from perfect and difficult to set up BUT nmm is the future 
... it's the module used from now to backup things like sharepoint, sqlserver 
and outlook so you will need to learn it one time or the other. Sooner you 
start, better it is no ?

There will be no coming back : the old modules are not developed anymore.
