Configure Alta Cloud Connector high availability mode

Last modified: Wednesday August 20, 2025.

Configure all of the Avigilon Alta CAlta Cloud Connectors in a Server group to work in high availability mode.

Prerequisites

A high availability group must contain exactly three Cloud Connectors, all attached to the same network, and sized appropriately that the camera workload and storage can be handled by any two of the three Cloud Connectors.

Risk of damage to equipment or loss of data!

If the connection to one or more Cloud Connectors fails, perhaps due to a power outage, during the configuration of the high availability mode, it can lead to the Cloud Connector becoming unavailable.

We strongly recommend that you create and save backups of each Cloud Connector within the Server group before enabling high availability mode, to enable the Cloud Connector to be restored to its original configuration in the unlikely event of this situation occuring.

Task — Create a high availability Server group

  1. Choose Tools Tools > System System.
  2. From the Cloud Connectors area, select the Server group of interest.
  3. From Cloud Connector group settings, click Enable high resiliency.
    The Cloud Connectors communicate with each other, making copies of configurations and databases to be used in the event of a fail-over. This process might take several minutes to complete, depending on the number of Cloud Connectors and the number of devices connected to each one.
  4. The Server group now shows the high availability mode icon high availability icon, indicating that all Cloud Connectors within that Server group are enrolled in the high availability group.
  5. Click Done.
