Abstract:
1. A system for replicating a deduplicated storage system comprising: an originator deduplicating system, wherein the originator deduplicating system breaks a data file into a plurality of segments using a processor and stores the data file by storing each segment of the plurality of segments by storing either a data segment or a reference to a previously stored data segment that is identical to the data segment, and wherein information on how to reconstruct the data file is stored on the originator deduplicating system; and a replica system replicating the originator deduplicating system, wherein the replica system is different from the originator deduplicating system, and wherein the replica system stores a copy of each data segment stored by the originator deduplicating system to enable reconstruction of the data file and receives information regarding updating stored segments from the originator deduplicating system, and wherein the information on how to reconstruct the data file is transferred from the originator deduplicating system to the replica system.
