If you do use Odoo's website builder for your website, as has been stated in many of the other chapters, back up your database often. All of the web pages that you create are stored inside your database, so you must back it up to make sure that you have a copy of your website. Additionally, you will want to make sure you keep your Odoo application backed up as well, because the static themes, images, and CSS files that are located there must be available to properly display your website.
In Chapter 13, Customizing Odoo for Your Business, you can find simple instructions on how to backup your database.
