rsync itself will not update anything on the source.
However, unixen will typically update the file's access time of any
files / directories / etc. that rsync accesses, perhaps that's your
problem. See if you can mount the file system "noatime" (that's for
linux); check to see that no applications depend on access times though
(e.g. mail programs compare modification time and access time to see
whether there's new mail).
