Abstract:
A host-based replication snapshot method. The method includes synchronizing a set of data objects stored at both a replication source node and a secondary node. The method further includes identifying changed data objects out of the set of data objects from the replication source node that have been modified during a time period between a first time and a subsequent second time. Metadata indicating the changed data objects from the replication source node is transmitted to the secondary node. A snapshot is then generated at the second time on the secondary node by using the metadata.
