    How to reduce load when cpanel backup?

    Hi

    I have Dual Xeon +2G ram cpanel with 700 accounts. Normally server load is only 0.5, but when donig backup load always rocket to sky like 18 . Also, another problem is back seems to take forever to finish, it could run from 03:00~17:00

    Any ideas how to reduce the load when backuping? I am using cpanel 's backup function (have not tried
    incremental backup yet)

    thanks

    I believe it has been well optimized already as you see non-backup time, server load is only 0.5

    Configure your backups to not to backup mysql since it creates a lot of dump schemas which can be restored later. If you backup the whole mysql directory using a custom script, it will cause less load.

    Try to run the script using /bin/nice so that it runs with a lower priority and takes less resources than other processes. /bin/nice --help

    Make sure also that dma is enabled, that can cause high loads when backups are running.

    man hdparm
