On this page:


Only two Servers can be added into 1+1 configuration.

Setting up 1+1 configuration

To initialize 1+1 configuration, add a second Server to the configuration. To do this, enter the IP address and click LINK.

Next, activate the Force local archive replication parameter if you want the replication to the backup archive to be continuous regardless of the location of the master node.

Note

You can activate this parameter only at the 1+1 configuration setting stage or at the conversion to 1+1 configuration stage. Then you can activate this parameter only if you recreate the cluster.

To set up a cluster in this configuration, you must initialize the cluster after adding two Servers.

In this case, the master node will be located on the Server from which the cluster was initialized.

Converting to 1+1 configuration

If a cluster was initialized on one Server, do the following:

  1. Add a second Server to the configuration (see Creating a cluster).
  2. On the Configuration page, click CONVERT TO 1+1.
  3. Activate the Force local archive replication parameter if you want the replication to the backup archive to be continuous regardless of the location of the master node.
  4. Click the APPLY button to convert to 1+1 configuration.

Editing the configuration

You can edit the configuration. To do so, click the button. You can do the following:

Setting up archive replication

To set up archive replication, do the following:

  1. Combine the master and the backup nodes into one domain (see Adding a Server to an existing Domain).
  2. Create a local archive on the master node (see Creating archive).
  3. Add video cameras on the master node (see Adding and removing IP devices).
  4. Set up video camera recording to the local archive (see Configuring recording to an archive).
  5. Create an archive for replication on the backup node.
  6. Set up the replication from the local archive to the archive for replication (see Configuring data replication). The replication period should be set to Always.

Attention!

Archive replication is available only with the C-Werk Enterprise license (see C-Werk license types). 

How replication will run

When the master node is migrated to the backup Server:

  • a temporary archive will be automatically created in the С:/temp_arch folder of the backup Server as a 10 GB file;
  • video cameras will record into the temporary archive;
  • replication from the temporary archive to the archive for replication will be simultaneous.

If the master node is migrated bask to the master Server, the recording will be made to the local archive.

You need to use different archives to view camera recordings:

  • to view the recordings when the master node was on the master Server, use the local archive;
  • to view the recordings when the master node was on the backup Server, use the archive for replication (see Selecting an Archive).

Attention!

  • If the backup Server fails when the system is running, you cannot stop the master node. 
  • If the backup Server is unavailable, you cannot restart the master node.
  • If the main node is located on the backup Server, then face recognition and license plate recognition by lists using detection tools will not be available until the main node is moved back to the master Server.
