+Having a compressed file and synchronized between two computers using rsync, 
this option allows after changing a file not to send an entire new archive but 
just a small portion of it. Normally, after a change in any file of an archive, 
compressing algorithm can generate completely different archive that differs 
from the old one. This causes rsync to transmit entirely new version to the 
remote computer. With this option, rsync is able to transmit just the changed 
portions (plus some minimal padding in the area of the archive that necessarily 
changed as a result of the changes in the file).
