John:

The first time you create a class that has both an 
incremental and a full schedule and the incremental is 
set to run first, it will essentially be a FULL 
backup.  Remember an incremental is based off of the 
last FULL, since there is no full to reference, then it 
will backup everyting.

As far as your manual execution of an incremental 
schedule, I have never seen that happen with any 
version of NBU including 3.2.  In  your class, do you 
have both a FULL and an INCRM schedule?  Or do you have 
a class with FULL scheds and a class with INCRM 
scheds?  If it is the later, then I can understand how 
the INCRM manual may result in a FULL backup.  Your 
class should have both an INCRM and a FULL schedule.

Hope this addressed your questions.
