Also, if running on linux, investigate ionice.
This, given CFQ disk scheduling (the default in recent kernels, I
believe) will cause rsync to play nice with IO resources, whereas "nice"
handles CPU load. rsync is often much more IO intensive than CPU bound.
I often run rsync with 'ionice -c3 rsync ....'
