Historian Data Mirroring

If you have purchased an Enterprise license for Historian and your license entitlement includes mirror nodes, you have the option of setting up to three mirrors (primary server + two mirrors).

Data mirroring provides continuous data read and write functionality. In a typical data mirroring scenario, one server acts as a primary server to which the clients connect.

To create a mirror, you must add mirror nodes and establish a data mirroring session relationship between the server instances. All communication goes through Client Manager, and each Client Manager knows about the others.

Mirrors must be set up in a single domain.
