Unless you do it properly, and do your QoS on routers in the middle.
Classify by port, put rsync traffic in to a low priority queue, and
everything else in to a higher priority queue.
The assumption is that you *can* classify by port - if you're using
ssh or some other shared service as the transport then that might not
work so well.
There are some things you can do to lessen the impact of using
something shared, especially when the service is used for something
interactive - ie. classify large packets differently to smaller
