I think the -R is the problem.

Yes, that's what it normally does.

By the way, -c is almost always unnecessary extra overhead. Since you're
copying the timestamps (implied by -a), you could take the default behavior
and have it quickly skip any file who's timestamp and size matches.
Also, -l is redundant since it is also implied by -a.
