--itemize-changes will cause rsync to tell you what it thinks is


Hi, thank you so much! Today I used a little different way of doing it, and 
another computer, and the behaviour is the same. It seems that the reason is a 
different timestamp. So the whole file is replaced just for this? I've always 
read that Rsync was using an advanced checksum mecanism instead of 
timestamps-only?


Are you so sure rsync actually copies the file? It should correct the timestamp 
and tell you it did.

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).



different.  Also, -z is counter-productive when rsync isn't networking.


Thanks again. It seems that "--progress" is redondant with "-P"(but it's 
because I use a list of rsync commands skeletons, and some doesn't have 
"-P" and I want to be sure to always have the progress indication).
But, since I will now always use "-i", do "-v" and "--progress" add 
something to "-i"?




-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.
