The reason for that is pretty simple... Rsync isn't reading the
existing file to find out that it is the same. Doing so would normally
be a waste of rsync's time. A better question is why are your files
changing timestamps when the data is the same.

I am using rsync with --backup --backup-dir to keep copies of files
which have changed as part of an incremental backup system. However, if
only the timestamp has changed, it creates a copy of the file in
--backup-dir, and if thousands of large files have their timestamps
changed, this can wast
