Abstract

Systems and methods for data snapshot replication are disclosed. In an exemplary implementation, a method for data snapshot replication may include inserting a token into a replication link when a data snapshot is generated at a source. The token may be inserted into the replication link while input/output (I/O) operations are quiesced. The method may also include generating the data snapshot on a target in an order that the token is received. This enables systems which are replicating data to also replicate or duplicate snapshots without transferring additional data or re-transmitting the data in the snapshot.
