This example pushes the process IO into the lowest end of the "best effort" class:

ionice -c2 -n7 find...

Change -c2 to -c3 to ensure your process will only run when the IO subsystem is otherwise
idle.

This example drops the processor allowance to a low priority:

nice -n12 find...

Change -n12 to -n19 for the least possible priority.

Combine them for maximum effect:

ionice -c2 -n7 nice -n12 find...
