Before setting up a cluster in this configuration, you have to initialize the cluster after two Servers have been added.

In this case, the primary node will reside on the Server from which the cluster was initialized.  

If a cluster has been initialized on one Server only:

1. Add the second Server to the configuration.
2. Click the Convert to 1+1 button on the Configuration page.
   

If necessary, you can further edit the configuration. To do so, click . You can perform the following actions:

• activate / de-activate the self-diagnostics service;
  

• change logging parameters;

In this configuration, a local Archive (video footage) will be automatically created as a 10 GB file located in the C:/temp_arch folder.

If a node is transferred to a backup Server, the primary archive must be replicated as a backup archive. To do it, follow the steps below:

1. On the backup node, create an archive for replication (see Creating archives).
2. On the primary nodes, configure the replication from the primary Servers' archives to the backup node's archive. The replication period should be set to Always (see Configuring data replication). You have to set the replication time period to Always.
