Creating a virtual access point in time on an object based journal replication

摘要

A storage system comprises a production site in operable communication with a replication site, and an object store, comprising a plurality of data objects associated with data stored in at least one data storage entity of the production site, disposed at the replication site. The replication site is configured to generate a virtual access point in time (PIT) based at least in part on the plurality of data objects, by providing a plurality of nodes in operable communication with the storage system, where each respective node is configured to, substantially concurrently, perform a MapReduce operation to generate a respective first set of disk objects based on the plurality of data objects, and to create a respective set of metadata objects. The first set of disk objects and the first set of metadata objects are merged together into a virtual access PIT from each of the plurality of parallel nodes.
