It will also keep any fulls needed to support the number of incrementals 
you keep.    Normally you end up with one more full than your 
FullKeepCnt because of this but it will depend on your incremental 
counts.   Running fulls more often in the schedule would reduce the need 
to keep them as the backing for subsequent incrementals.

Data that does not change between runs should not take additional 
storage, but even a slight change will make a new complete copy.  If you 
have large growing log files you might rotate them more often. If you 
have large mailbox files in standard unix format you might convert to 
maildir format.  This kind of change helps backuppc retain the unchanged 
files instead of duplicating the content in growing files.
