    "type": "ssh",
    "settings": {
        "location": "/mnt/snapshot",
        "host": "123.123.123.123",
        "port": 22,
        "username": "snapshot_user",
        "private_key": "/home/snapshot_user/.ssh/id_rsa",
        "known_hosts": "/home/snapshot_user/.ssh/known_hosts",
        "compress": true
    }
}'

Name	Type	Description

Create/Restore Snapshot

The usage is the same as Elasticsearch's one. See snapshot and restore.

Note

In a large cluster, you may need to increase the MaxSessions parameter of your sshd in repository server.
