Asynchronous Disaster Recovery (DR)

With asynchronous DR, you can replicate Kubernetes applications and their data between two Kubernetes clusters. Here, a separate Portworx Enterprise cluster runs under each Kubernetes cluster.

The source Kubernetes cluster asynchronously backs up apps, configuration and data to the destination Kubernetes cluster.
Incremental changes from Kubernetes applications and Portworx data are continuously sent to the destination cluster.
In case the source cluster becomes unavailable, you can activate the applications in the destination cluster.

You can find a list of supported Kubernetes resources in the Supported Kubernetes article.

Follow the instructions in the following sections in order to set up an asynchronous DR for your cluster.

NOTE: The following sections require specifying a <namespace>. In your environment, update this to the namespace where Portworx is installed. Typically, Portworx is installed in either the kube-system or portworx namespace.
