As with previous Graphic Hub versions, each modifying statement in a cluster environment will be replicated towards the Replication server to guarantee real-time redundancy. This means that all items, including the Pilot data on the main instance, will be replicated to a second Graphic Hub instance in real-time. In case of a fail-over situation, all connected clients on the main instance will be automatically redirected to the replication server. As soon as the main server resumes operation, all items created or modified in the meantime will be automatically transferred from the replication server to the main server.

To check if main and replication are in sync, connect to both Graphic Hubs as an administrator user using the Graphic Hub Manager, then proceed to check for Pilot Server Differences.
