To make Joomla backup of your website through hosting you have to make 2 archives like in manually Joomla backup, but using another method. We are using Hostgator hosting and we will show you how to make backup through hosting on the hostgator example. Follow steps bellow:
Enter cPanel of your Joomla website and in Files section find Backup Wizard.
After you have entered Backup wizard, you will see its options window, to start making Joomla backup choose Backup button.
On the second tab of Backup Wizard window you will be able to choose what backup to make:
Depending on what aim you are pursuing choose needed variant. In our example we have chosen Partial backup. First we will make an archive of Home Directory.
First part of your Joomla backup will be the Home directory archive, press on Home directory button. After you have pressed on the button the Backup wizard will compress Home directory into archive and save it on your local computer through your browser. After archive is saved press on Go back button.
After you have pressed Go back button, you will be located to the Backup Tab. Now you have to make a full Backup of all your databases. Choose MySQL Databases and press on each database you have. The Backup wizard will save databases on your local computer through browser.
