With an urge to learn more, you must understand the concept of backing up a subdomain. Most of the WordPress users don't have any idea about the difference between a domain and subdomain.
A domain is an address where internet users can access your website. Computers use IP address to identify a website, but it’s not possible for humans, so the simple identity having character and numbers is a used.
Every domain name is unique. Let's say you have a website (example.com), this is a domain name.
A subdomain is created using the primary domain; you may have noticed, many websites have a separate blog or forum section.
For example blog.example.com, forums.example.com, these are subdomains. I would like to mention that some subdomains are used for a different purpose, for example, mail.example.com is used for emails and there is no CMS installed.
The process of backing up a subdomain is applicable when you run a website on it. To backup a domain and its database, you can use the full backup option from cPanel, but when you have a subdomain, you require to take manual action.
Although you can download the full backup of the home directory and then extract your subdomain folder, it can be complicated.
In this tutorial, you're going to learn the manual method to backup your subdomain.
