Database Replication
Replication of the CUIC database (the maintenance and synchronization of multiple copies of
the cuicdatabase (CUIC) across servers) is essential for the Unified IC cluster.
Unified IC uses the update-anywhere enterprise replication model based on a topology of Fully
Connected Database servers. Each database server has connection to all other database servers.
Data can be transferred from any machine to all others.
Figure 16: Database Replication
Data is replicated immediately - as soon as changes are made. Changes that are apparent in the
User Interface (such as the addition or deletion of a dashboard or a change to a report definition)
are evident across all devices when the page is refreshed, provided that all devices in the cluster
have all the required network connections and CPU power to do all processing.
Conflict resolution (for example, when one user is deleting an object that another user is updating)
is handled on a last-update-wins basis.
Backup
You can perform a manual or a scheduled backup on a configured backup device using the
Backup menu in the Disaster Recovery System application.
A backup device is logical mapping to a tape or a remote (NFS) location. Each backup device
can store up to 14 backups.
You can back up all or some nodes in the cluster. The Controller node must be running for any
backup to take place. Any Member nodes that are to be backed up must also be running.
Although you can run a backup and continue operations, it is best to back up at off-peak times.
