Configure a backup unit or a connection synchronization for external high availability
You can now for an engine, configure a backup unit or configure a connection synchronization for external high availability.
- You cannot enable both the Backup Unit and the Connection Synchronization for External High Availability feature at the same time.
The Backup Unit feature is a high availability functionality that is used to manage small remote sites where engine clustering is not possible or only a single IP address can be used. This functionality allows synchronization of the connection between two engine nodes and only one node is active at a time. Hence, if one of the engine nodes is unavailable the engine operations are not interrupted as the second engine node becomes active.
The Connection Synchronization for External High Availability feature is used to enable high availability in Public Clouds by allowing synchronization of connections between 2 to 3 single engine configurations.
Steps
- Select Configuration.
- Browse to .
- Right-click an engine, then select Edit <element type>.
- In the navigation pane on the left, browse to .
- Configure the settings.

Note: To add an engine to a synchronization group, you must navigate to the section of the engine to enable the Connection Synchronization for External High Availability, and then select the group. This needs to be done for each
engine individually.
