I know that all CMS or CMC platforms have some sort of walkthrough for their users to fully backup and restore the database or the whole website. While we all can perform such backups (and there are even plugins which automate the whole procedure) and restore them in necessity (such as when we migrate to a new server), one can also backup the whole website by means of such control panels as Directadmin or Cpanel. Now, I just want to know if it is necessary for us to do database or website backups the way they are described by a specific CMC or CMS developer even after we perform a whole website backup in a control panel such as DA?

An example of such CMS platforms is moodle. Moodle Docs describes how we can backup and restore moodle in here. So do we, out of necessity, have to make the backup the way described, or we can simply do it the Control panel way? Thanks
