Redundant backup device and method

摘要

The present disclosure relates to a redundant back up device (106). 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 (104) and to the redundant backup device (106), writing the transmitted data to a writing medium contained within a writing device (108) 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 (114) of the redundant backup device. By caching the transmitted data in this manner, the data can be rewritten to the writing medium should a failure occur.
