Get high load, when WHM backup progress, even in 2am

My dedicated server only used for one website, the disk usage in /home directory is 25Gb, where 5Gb is mysql database

In WHM > Configure Backup > I set ‘Backup Status’ to Enabled, with time Daily, Weekly, and Monthly

i already install plugins ‘Configure cPanel Cron Times’a too, and set it in the most off peak time, 2am

but its still make the load become high, can be more than 10, sometime i cant open the website when the server load become high, when WHM backup progressing in the backend, but few minutes again the load is reduced and the website can opened again

please help how to reduce the load from backup progress, or slower the progress

In ‘Backup SQL Databases’, is it set ‘Per Account Only’ will be help, instead choosing ‘Per Account and Entire MySQL Directory’?

You have the backup and crons scheduled for the same time ?

If so set the crons all different, and set the backup for a different time.

Also make sure the settings for how often the stat programs update and make sure its not at the same time as other processes.

Use a different backup program instead of the cpanel backups - it’s very I/O intensive and a big account backup can kill a slow server using SATA. Consider doing a MySQL dump to your home directory and then rsyncing your home directory files somewhere.

Alternatively, it could be that the SQL dump is locking tables on your database thus preventing access to your site… you could consider doing a skip-locking dump of the individual tables (not good if you need to enforce referential integrity between tables in your db) or setting your tables to innodb to prevent entire table locks.

no, only backup at a time, the cron job is set the time only for this whm backup process (cpbackup)

ah so get high load using whm backup, not only my problem

what is the recomended programs for this?

I have compression turned off and incremental changes only. Some sites I have exceed 40-50 gigs in size I have no problems. Change to this configuration if you still have a problem you have something else wrong.
