A tar incremental looks only at the timestamps on the target directory (and 
will 
miss new or moved files with old timestamps).  Rsync compares directory entries 
with the last full run to catch any new files regardless of timestamps and to 
note any deletions.  And it still transfers the entire directory tree before 
starting.  If you have a very large number of small files that never change, 
you 
might improve things by moving them into larger zip or tar archives.
