RKE also added two commands that for etcd backup management:
```
./rke etcd backup [NAME]
./rke etcd backup --name NAME
```
and
```
./rke etcd restore [NAME]
./rke etcd restore --name NAME
```
The backup command saves a snapshot of etcd in `/opt/rke/etcdbackup`. This command also creates a container for the backup. When the backup completes, the container is removed.
The backup command saves a snapshot of etcd from each etcd nodes in the cluster config file and will save it in `/opt/rke/etcdbackup`. This command also creates a container for the backup. When the backup completes, the container is removed.
