Abstract:
1. A backup system for storing data objects to be backed up on secondary storage devices, the backup system comprising a plurality of buffer memories for storing the data objects to be backed up and for coupling the data objects to be backed up with the secondary storage devices, the back up system being configurable to couple at least a sub-set of the buffer memories in a daisy-chain for sequential storage of the data in the daisy chain as the data objects to be backed up on one of the secondary storage devices, at least one backup media agent having a plurality of the buffer memories, a program module for sequentially writing data from the at least the subset of the buffer memories to an output adapted to be coupled to a secondary storage device assigned to the at least one backup media agent, and at least one mirroring backup media agent, the mirroring back up media agent comprising a plurality of further buffer memories and a further program module for writing data from the further buffer memories to one of the secondary storage devices assigned to the at least one mirroring backup media agent, and at least a sub-set of the buffer memories of the at least one backup media agent being coupled in a daisy-chain configuration to at least a sub-set of the further buffer memories of the at least one mirroring backup media agent.
