    Making backup is generating huge load on server. It is related to IOwaits on system.

    It is possible to nice backup process?

    ionice -c3 nice -10
    This command is not working, because it will only nice the parent process not child.

    Hello :)

    You can browse to the "Stats and Logs" tab in "WHM Home » Server Configuration » Tweak Settings" and modify the following option:

    "Extra CPUs for server load"

    Per it's description:

    The load average above the number of CPUs at which cpuwatch, cpanellogd, backups, and CPU stats consider the system to be in a critical load state. For example, a server with 4 physical CPUs and a value of 2 in this field will be considered “critical” in these cases once the load reaches 6.

    Thus, you can ensure backup generations are suspended when the load reaches a certain point.

    Thank you.
