Before starting the restore operation, a snapshot file must be present. It can
either be a snapshot file from a previous backup operation, or from a remaining
[data directory]( https://etcd.io/docs/current/op-guide/configuration/#--data-dir).
Here is an example:
```shell
ETCDCTL_API=3 etcdctl --endpoints 10.2.0.9:2379 snapshot restore snapshotdb
```
For more information and examples on restoring a cluster from a snapshot file, see
[etcd disaster recovery documentation](https://etcd.io/docs/current/op-guide/recovery/#restoring-a-cluster).
