If you use

  --exclude "#cvs*" --exclude ",*,"

then all of the files that you rsync to the remote site should be free
of any data corruption. When cvs moves from ,file, to file,v it is an
atomic rename operation, so as long as rsync is ignoring the ,file,v RCS
'lock files' and the '#cvs*' lock files, you will not have a 'corrupt'
copy of the repository... of course, this does not mean it will be a
'sane' copy of the repository as you may have copied only some files
that were in the process of being changed during a commit.

If you are worred about having a consistent repository, then you may
find it desirable to look at cvslock

  ftp://riemann.iam.uni-bonn.de/pub/users/roessler/cvslock/

and have it lock the repository directories of interest before starting
your rsync and then unlock them. You will still want to have the
- --exclude "#cvs*" to avoid dragging cvs locks to the remote site.

Finally, have you considered doing a 'pull' from the secondary to the
primary using cvsup on the client and cvsupd on the server?

You may find that the cvsup/cvsupd is really the 'better' solution:

    
ftp://ftp.freebsd.org/pub/FreeBSD/development/CVSup/sources/cvsup-snap-16.1h.tar.gz

you will also need to fetch a copy of a Modula-3 compiler ezm3

ftp.freebsd.org/pub/FreeBSD/development/CVSup/ezm3/ezm3-1.1-src.tar.bz2
ftp.freebsd.org/pub/FreeBSD/development/CVSup/ezm3/ezm3-1.1-src.tar.bz2.asc

note that some pre-built Modula-3 compilers exist such as

ftp.freebsd.org/pub/FreeBSD/development/CVSup/ezm3/ezm3-1.1-SOLgnu-boot.tar.bz2

depending on the CPU type you have.

        Enjoy!
