Taking a backup of your cPanel hosting services periodically is an excellent idea and it covers you in the unlikely event of data loss. Taking a backup is a very easy process which provides peace of mind. Please see these steps for taking a full cPanel backup:
Click Backup, and select Full Backup. Leave Backup Destination set to Home Directory. Enter your email address to be notified when the backup finishes.
Click Generate Backup, and wait until it completes. This can take some time if you have a large number of files.
Once it’s finished, go back to your cPanel home and click Backup.
Click Download or Generate a Full Website Backup.
Download the backup you’ve just completed. Please ensure you store your backup in a reliable place.
Note: it is best practice to remove a backup from your hosting after downloading it to your computer. Per our Acceptable Use Policy, old backup files may be deleted from the server periodically.
