- Rancher Kubernetes Engine v0.1.7 or later

  The commands for taking `etcd` snapshots are only available in RKE v0.1.7 and later.

- `rancher-cluster.yml`

  You'll need the RKE config file that you used for Rancher install, `rancher-cluster.yml`. You created this file during your initial install. Place this file in same directory as the RKE binary.

- You must restore each of your `etcd` nodes to the same snapshot. Copy the snapshot you're using from one of your nodes to the others before running the `etcd snapshot-restore` command.
