Your rsync isn't networking.  That means --whole-file is forced making 
rsync work pretty much like cp.  If rsync was networking it would 
determine what is different about the files then use the existing 
version + changes to make a new file (this is just extra effort when 
rsync isn't networking).

-i, -v, and --progress all only affect the output.  Once -i is in play 
-v adds a header and footer and --progress of course  adds the per-file 
progress bar.  -P is just --partial and --progress.  I am not a fan of 
-P as those 2 options are very different and I don't really see why they 
should go together.
