Abstract
Generally described, aspects of the present application correspond to enabling rapid duplication of data within a data volume hosted on a network storage system. The network storage system can maintain a highly distributed replica of the data volume, designated for duplication of data within the volume and separate from one or more other replicas designated for handling modifications to the data volume. By providing increased parallelization, the highly distributed replica can facilitate rapid duplication of the volume. When a sufficiently large request to duplicate the data volume is received, the system can create additional duplicate portions of the volume to further increase parallelization. For example, a partition of the highly distributed replica may be repeatedly duplicated to create a large number of intermediary duplicate partitions. The intermediary duplicate partitions can then be used to service the duplication request rapidly, due to increased parallelism.
