    When backups run, the majority of our servers die completely as pkgacct/cpbackup takes up all the I/O and everything comes to a halt.

    As soon as I kill pkgacct/cpbackup, the server goes back to it's normal self.

    Is there any way to fix this? Give it a MUCH lower priority on the system? Obviously I need to run backups, however I can't have the server die every 2 days.

    It already is set to do incremental backups and no compression.

    If the IO wait is the problem, you should add another drive just for backups.
    That should reduce IO wait a lot.

    Do you guys run anything on that backup drive?

    Please paste the output of iostat so we can check the current IO statistics for the server.
