Volume Replicator provides the option to pause replication from the Primary as well as the Secondary host. However, there is some difference in the way the pause is effected. Note that pausing the Secondary from the Primary or from the Secondary, effectively results in pausing replication. If the pause was initiated from the Primary host, the Secondary gets disconnected. After a resume operation is performed, the Secondary gets connected automatically and the pending updates from the Replicator Log are sent to Secondary. However, in the case of the Secondary initiated pause, you can specify a checkpoint that marks the point when the Secondary was paused on the Primary Replicator Log. You can take a backup of the Secondary and then resume replication. In future if the Secondary data volumes fail then you can apply the backup to the Secondary data volumes and use the Restore with checkpoint option to synchronize the Secondary with all the writes that had come in after the checkpoint. When you perform a Restore, the Secondary is updated only with updates from the checkpoint.
