English to Chinese Tech/Engineering IT (Information Technology) vSphere Replication

After baseline synchronization is complete, vSphere Replication switches to transferring only the blocks of data that have changed. The vSphere kernel itself tracks unique writes to the disk files of protected virtual machines, and identifies and replicates only those blocks that have experienced unique writes during the configured recovery point objective. This ensures a minimized amount of data is sent over the network to the target, and allows for{ aggressive }recovery point objectives. Once unique data is sent, it doesn't need to be sent again. Only changes will be replicated, and the blocks sent to the target location's vSphere Replication Appliance.
