Efficient volume replication in a storage system

Abstract:

An indication to replicate, for a second storage resource, a volume that is stored at a first storage resource may be received. A snapshot of the volume that is stored at the second storage resource may be identified. Data with operations to data blocks of the volume may be identified. A sequence number range, containing one or more sequence numbers, associated with the snapshot of the volume that is stored at the second resource may be received. Furthermore, a portion of the data associated with the operations to the data blocks of the volume based on the sequence number range that is associated with the snapshot of the volume that is stored at the second resource may be received to replicate the volume at the second storage resource.
