Site Info - You can update your Website or business name, your contact email address, select a business category that best describes your business, edit your address and phone number (and indicate whether or not to display them on your Web page and mobile Website), and connect with your Twitter® and Facebook® accounts.
This changes your information throughout the Website.

Backup/Restore - You can create a backup of your current website or restore a previously saved version of your website. You can have up to five backups of your website.
When finished, click OK to save your changes and close the Website Settings window.
