Patrick, 

The primary difference is this.

When NBU runs it via its automatic schedule, it causes bprd to suspend its 
ability to submit any jobs to the queue (actually it suspends its ability to 
wake-up bpsched that looks for something to do).  So if no backup jobs are 
running then your database will be in a quieted state suitable for a proper 
backup.  

When you run it manually, bprd is not suspended and jobs may potentially be 
submitted during the backup putting it in a questionable state.  You will have 
to manually suspend the request daemon.
