In order to do a backup of your database through a cron job, you can set this up in cpanel. Click on Cron Job, then select Standard or Advanced. You can select the backup frequency that you need then enter the command to backup. Here is a sample cron job:
0 0 * * 0
date=`date -I`; /usr/bin/mysqldump -uDBUSERNAME -pPASSWORD dbname > /home/CPANELUSERNAME/FILE_NAME_HOME_DIRECTORY$date.sql
This cron job will do a backup of the database every Sunday at midnight. Then it will save the backup with the current date appended to the file name.
A few notes:
-uDBUSERNAME – there should be no space between -u and DBUSERNAME, DBUSERNAME is the username of the database you are trying to backup.
-pPASSWORD – there should be no space between -p and PASSWORD, PASSWORD is the password of the database user.
dbname – this is the name of your database.
/home/CPANEL_USERNAME/BACKUP_NAME$date.sql – cpanelusername is your username to log into cpanel, and this will save the backup in your home directory (you can change it to whatever directory you want). You can call the backup whatever you wish but adding $date at the end will append the date to that backup.
