Because the backups on my server takes far too long to run (24 hrs) I tried to lower the IO level in the 'tweak settings'. I entered 3 in the prio field, but the backup is still runs with lvl 4: [2016-11-17 00:15:03 +0100] info [backup] Setting I/O priority to reduce system load: none: prio 4 The backup on this server takes forver. The other servers with the same specs and amount of data take 15 hrs to complete, on this server it takes 24 to 30+ hrs. Load is within bounds.

  Hello, The availability of ionice depends on the I/O scheduler utilized on your system. You can run the following command to see if a scheduler is enabled:
  cat /sys/block/$sda/queue/scheduler
  Replace $sda with your disk name (e.g. sda, vda). There's also a useful thread on StackOverflow on schedulers at: Selecting a Linux I/O Scheduler Thank you.
