How do I restore Elasticsearch snapshots to another cluster?

The steps I've following are:

1. make a backup of the index on the original cluster.
2. create the snapshot repository on the other cluster, just a copy of the original cluster: "backup" : "type" : "fs", ...
3. copy the content of /var/elasticsearch/backup of the original cluster to the another one.
4. restart the elasticsearch.
