Facebook to backup its servers with low-power storage devices at 'Sub-Zero' data center

Data backups come in all shapes and sizes. For some, they take the form of external hard drives or a slice of the amorphous cloud. As for Facebook, its upcoming solution is low-power deep-storage hardware contained within a 62,000 square-foot building in Prineville, Oregon near its existing Beaver State data center. Unofficially referred to as "Sub-Zero," the facility will store a copy of the social network's data in case its primary servers need to be restored in an emergency. Rather than continuously power HDDs that are only occasionally used, the new setup can conserve energy by lighting-up drives just when they're needed.
