A method and system for sharing pre-calculated fingerprints and data chunks amongst storage systems on a cloud local area network. Specifically, the disclosed method and system extend the functionality of data deduplication storage systems to include querying other data deduplication storage systems on the cloud local area network for fingerprints, corresponding to data chunks, when these fingerprints and data chunks are not stored locally. The transfer of data chunks between one data deduplication storage system to another through the cloud local area network may be a faster and cheaper alternative to the transfer of data chunks between a data deduplication storage system and a client through a wide area network.
