Click the "**All objects (entire system)**" field. This will restore EVERYTHING back into your account such as email accounts and emails, website files, databases, etc. - Your whole hosting account and all of its components.
If you choose "**Selected objects**", you will be given a list of components to choose from. An example would be if you only wanted to restore your website files, you would click on "**Selected objects**" radio button and choose "**Website Files**" from the drop down list that would appear.
In this example, we are choosing to restore the entire hosting account with all of its components.
