This procedure describes how to use RKE to restore a snapshot of the Rancher Kubernetes cluster. The cluster snapshot will include Kubernetes configuration and the Rancher database and state.

This will restore the Kubernetes configuration and the Rancher database and state.
Additionally, the `pki.bundle.tar.gz` file usage is no longer required as v0.2.0 has changed how the [Kubernetes cluster state is stored]({{<baseurl>}}/rke/latest/en/installation/#kubernetes-cluster-state).

### 1. Preparation
You will need [RKE]({{<baseurl>}}/rke/latest/en/installation/) and [kubectl]({{<baseurl>}}/rancher/v2.x/en/faq/kubectl/) CLI utilities installed.
It is advised that you run the restore from your local host or a jump box/bastion where your cluster yaml, rke statefile, and kubeconfig are stored. You will need [RKE]({{<baseurl>}}/rke/latest/en/installation/) and [kubectl]({{<baseurl>}}/rancher/v2.x/en/faq/kubectl/) CLI utilities installed locally.
Prepare by creating 3 new nodes to be the target for the restored Rancher instance. See [Kubernetes Install]({{<baseurl>}}/rancher/v2.x/en/installation/k8s-install/create-nodes-lb/) for node requirements.
Prepare by creating 3 new nodes to be the target for the restored Rancher instance. We recommend that you start with fresh nodes and a clean state. For clarification on the requirements, review the [Installation Requirements](https://rancher.com/docs/rancher/v2.x/en/installation/requirements/).
We recommend that you start with fresh nodes and a clean state. Alternatively you can clear Kubernetes and Rancher configurations from the existing nodes. This will destroy the data on these nodes. See [Node Cleanup]({{<baseurl>}}/rancher/v2.x/en/faq/cleaning-cluster-nodes/) for the procedure.
Alternatively you can re-use the existing nodes after clearing Kubernetes and Rancher configurations. This will destroy the data on these nodes. See [Node Cleanup]({{<baseurl>}}/rancher/v2.x/en/faq/cleaning-cluster-nodes/) for the procedure.
> **IMPORTANT:** Before starting the restore make sure all the Kubernetes services on the old cluster nodes are stopped. We recommend powering off the nodes to be sure.
