I am looking into starting a blog for the government office I work for. I am debating whether to use WordPress.com or go with a commercial hosting service that supports WordPress. I think my main concern at this point is guaranting that we have completed access to our records at any time. I understand that WordPress.com backs up hourly; but what if WordPress.com was to stop conducting business? Is there a utility I might use that would allow me to make a local backup of our blog?
