Abstract
Techniques and mechanisms described herein facilitate the replication of data between storage nodes. According to various embodiments, a request to provide a data chunk to a target storage node may be received at a source data storage node. A reference data chunk may be identified based on fingerprint information associated with the requested data chunk. The reference data chunk may be stored on the target storage node. The reference data chunk and the requested data chunk may each include a first data portion. Data chunk reconstruction information may be transmitted from the source data storage node to the target data storage node. The data chunk reconstruction information may identify the reference data chunk. The data chunk reconstruction information may include data difference information for constructing the requested data chunk at the target data storage node based on the reference data chunk.
