ok, thanks for that.

We have used these docs, they have been very helpful, and the data replication over a wan is working well.

The only thing we were worried about was once the system was running, for say 6 months, and we decide to add a new volume to the main storage server and then setup replication of that new volume, that it would take considerable time for the initial replication over the wan and we were looking for a way to manually copy just that initial replication (as I gather once the first one is complete it is incrementals afterwards).
