beginners help with cpanel backup and pigz

Every day at around 10:30am on our server a cpanel backup/pigz process will start up on a random account. This will usually be the busiest time on our server for web traffic. Mysql processes queue will get backed up as this is happening, perhaps because there is a mysql dump that happens just before pigz? Websites will then get very slow and mysql could take hours or more to recover. We told pigz to only use 8 processes when running to reduce load. This does not help so far. Is there anything else we can do to mitigate the things that happen when the backup starts?

  Thats exactly what we needed! We were incorrectly advised by our hosting partner that this was not possible. Thank you.

  Wait this screen says "Statistics" is that the same as the backup schedule as well?

  Actually, the interface I referenced is in-fact for statistics only. While this feature is not available for backups, 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.
