Perhaps as Eberhard suggested, ionice might be useful and is
part of the util-linux-ng package...

 -c The scheduling class. 1 for real time, 2 for best-effort,
    3 for idle.

 Idle. A program running with idle io priority will only get
 disk time when no other program has asked for disk io for
 a defined grace period. The impact of idle io processes on
 normal system activity should be zero. This scheduling
 class does not take a priority argument.

ionice -c3 rsync ... etc
