Open source database provider 10gen is expanding into storage services, offering a hosted backup service for its flagship MongoDB data store. Using 10gen's backup service would save users from the work of setting up their own backup copies, which can be a challenge to implement, according to a 10gen statement announcing the new service. Administrators would have to set up a backup service that would need to be reliable, and not procure too much, or too little, hardware, for the job.
