In older versions of CygNet, VHS replication worked as a push model, where the source VHS service maintained a queue of compressed messages to be sent to another VHS. The source VHS would maintain the messages on its queue until it was successful in sending the messages to the destination VHS, or until the message expired subject to configuration parameters.
This feature set still exists in the VHS but is now known as History Data Forwarding. See VHS Data Forwarding for more information about this feature.
For information about replicating your Historian, see VHS Replication in the Replication section.
