Now we will use the snapshot backup to restore etcd as shown below. The restore command generates the member directory, which will be pasted into the path where the etcd node data are stored (the default path is /var/lib/etcd/). If you want to use a specific data directory for the restore, you can add the location using the --data-dir flag, but the destination directory must be empty and obviously have write permissions.
