Regularly backing up your site is vital, especially before upgrading your Joomla or making other changes to it.
Thanks to the huge Joomla community there are a lot of simple extensions to help you create a backup with just a click. We strongly recommend you using Akeeba Backup, which can work for all Joomla versions.
Installing Akkeba is a painless process and more on how to install Joomla extensions can be found HERE. (although the guide is for newer versions, the process is the same)
Once you have the Akeeba Backup installed, navigate to the Components tab -> Akeeba Backup.
The Akeeba backup will make a few server checks to see if your server is compatible with making a full backup of your website and after that you need to click the Backup Now tab.
Then, you will see a few options about your backup creation and you have to press Backup now again to proceed.
