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 pool of the data volume, include a number of replicas duplicating data of the data volume. By providing increased parallelization, the replica pool can facilitate rapid duplication of the volume. In one configuration, each partition of a new volume is mapped to an individual replica within the replica pool, which supports population of the partition with data. Each replica can further include a set of replica partitions, such that read requests from each partition of a new volume are distributed among a number of servers to provide additional parallelization.
