CodeGuard is the paid backup service offered by Bluehost. For the basic plan, it backs up your site daily, and informs you of any major changes to your site. However, they only offer 1 GB of storage and 3 restores per month.\r If you're running your website on WordPress, there are other (free) options. They have plug-ins that let you make automatic backups daily. You can even set these backups to save to a cloud service like Dropbox.\r You should consider CodeGuard only if you're using something other than WordPress. Otherwise, save your money and use a free plug-in instead.
