The files chosen for tar incrementals should be chosen entirely by timestamps 
with the cut-off being slightly earlier than the previous full run.  If you 
have 
large, changing files like databases, or mailboxes, or growing logfiles, they 
will be copied each time, and if you had files less than an hour old at the 
time 
of the full, they might be copied again in subsequent incrementals.

If you are concerned with the bandwidth used, you might want to switch to the 
rsync method in any case.
