HostGator control panel gives you to option to make an ‘instant’ backup of your entire cPanel account. It will archive your account and provide you with a link to download the backup. You can then use this backup file to restore your account on HostGator servers if need be.

This backup gets everything associated with your account: e-mail accounts (including the passwords and messages still on the system), FTP accounts, add-on/sub/parked domains, databases, mailing lists, EVERYTHING that is setup with your account.
