Accelerated deduplication block replication

Abstract:

Embodiments for, in a shared storage environment, managing data replication between first and second sites of a distributed computing environment by one or more processors. Metadata is pre-seeded from the first to the second site as an assembled metadata map. Data blocks corresponding to the pre-seeded metadata not currently stored at the second site are determined by the second site using the metadata map within a deduplication environment. A transfer request for the data blocks is returned by the second site to the first site.
