The complete replacement is necessary to snap any links (another undocumented feature). Someday -C should avoid touching the file if possible, so that it doesn't clobber the file's ctime and backups based on ctimes don't do unnecessary work. This is possible if none of the attributes except the file times would change, and fairly easy to implement if the file doesn't have any links.
