Unless you never write to the disk, that will still be lost in the noise

Consider a weekly backup of /usr with checksumming of the contents. A
partition that only changes with updates, so in principle it could be
mounted read-only except when I yum update. Although of course since it's
not SUPPOSED to change, an incremental backup should only be done after
that yum update. The main value I can see with atime on /usr is to identify
trash that I'm not using and that should be uninstalled.
But if it still bothers you, use rsync --open-noatime.
That would be handy if I actually needed atime! I hadn't noticed that one.
Although I'm reading that the containing directory's atime does get updated.
