I have a machine that suffers periods of resource contention (CPU or Memory or Disk or some combination) and I don't want Rsync to add to the problem when that occurs. Is it possible to setup Rsync to that it "slows dow" or stops during periods of contention (effectively being lazy)?

It depends on the resource, but you can do the following:

  • CPU: set the nice level of the process to a high value (lower it's priority)
  • Disk: set the ionice level of the process to an idle scheduling class
  • Network: use tc to set the network TOS or use the --bwlimit arguement
  • Memory: Interesting one - there's some complex methods using systemd or cgroups.
