Abstract
The present disclosure relates to a redundant back up device. Through use of the device, a method for backing up information can be performed that comprises the steps of transmitting data to be backed up to a primary backup device and to the redundant backup device, writing the transmitted data to a writing medium contained within a writing device of the primary backup device, and simultaneous to the step of writing the transmitted data to the writing medium of the primary backup device, caching the transmitted data in a data storage device of the redundant backup device.
