1. In the **Clusters** page, go to the cluster where you want to remove nodes.
1. In the **Machines** tab, click **⋮ > Delete** on each node you want to delete. Initially, you will see the nodes hang in a `deleting` state, but once all etcd nodes are deleting, they will be removed together. This is due to the fact that Rancher sees all etcd nodes deleting and proceeds to "short circuit" the etcd safe-removal logic.
1. After all etcd nodes are removed, add a new etcd node that you are planning to restore from.

- For node driver clusters, a new node is provisioned automatically.
At this point, Rancher will indicate that restoration from etcd snapshot is required.
1. Restore from an etcd snapshot.

As the etcd node is a clean node, you may need to manually create the `/var/lib/rancher/<k3s/rke2>/server/db/snapshots/` path.

1. Define `spec.cluster.rkeConfig.etcdSnapshotRestore.name` as the filename of the snapshot on disk in `/var/lib/rancher/<k3s/rke2>/server/db/snapshots/`.
1. The example YAML below can be added under your `rkeConfig` to configure the etcd restore:
```yaml

rkeConfig:
etcdSnapshotRestore:
name: <string> # This field is required. Refers to the filename of the associated etcdsnapshot object.

```
1. After restoration is successful, you can scale your etcd nodes back up to the desired redundancy.
