Backups are important and it seems you can never have too many! This web framework has the capability for creating a backup when desired, or remotely backing up the site and downloading to an off-site location. A backup is made of the database content, including the table structures, and of the web installed software framework and extensions. An entire site can be rebuilt from a backup, or can be replicated to another location for testing, redesign, or development.
Automated backups can be made daily or weekly, and keeping copies off-site is an added security toward disaster recovery. The more complex or more dynamic your site becomes, the more important it is to have frequent backups.
