Disaster recovery for managed Kubernetes Edge sites

Edge's disaster recovery procedure allows you to recover your data in instances where your Kubernetes cluster fails while Edge is running. This procedure is only applicable when your Edge site is installed on a managed Kubernetes cluster.

Use Case Scenario

Below is an example scenario which demonstrates when this procedure would be used and how to initiate it.

In this scenario, an Edge site has already been installed on Cluster A. We recommend that you set up a periodic backup for Cluster A to avoid losing your Edge site configurations. In the event of a failure, you have to uninstall Cluster A, reinstall Edge on a new cluster (Cluster B), and then finally restore the Cluster A Edge site backup on Cluster B.

Note You can follow the steps and use the commands in Reinstall an Edge site per your preferred installation method. However, in the case of a disaster, the Edge site would be installed in a new cluster, as shown below.

The process of recovering from a disaster requires the following steps:

  1. Set up a periodic backup of Edge on Cluster A.
  2. Uninstall the Edge site running on Cluster A.
  3. Install the new Edge site and restore a backup on Cluster B.
    • If you use the Helm chart method, the restore backup command must be run before you reinstall the Edge site.

Tip All steps require that the kubectl utility can connect to the cluster.
