Is there any way to create a dump file that contains all the data of an index among with its settings and mappings?
A Similar way as mongoDB does with mongodump
or as in Solr its data folder is copied to a backup location.
Cheers!

You can use cURL in a UNIX terminal or Windows command prompt, the Kibana Console UI, or any one of the various low-level clients available to make an API call to get all of the documents in an Elasticsearch index. All of these methods use a variation of the GET request to search the index.
You use GET to retrieve a document and its source or stored fields from a particular index. Use HEAD to verify that a document exists. You can use the _source resource retrieve just the document source or verify that it exists.
Here are three popular methods, you use to export files from Elasticsearch to any desired warehouse or platform of your choice: Elasticsearch Export: Using Logstash-Input-Elasticsearch Plugin. Elasticsearch Export: Using Elasticsearch Dump. Elasticsearch Export: Using Python Pandas.
Because Elasticsearch Dev Tools and standard Elasticsearch search API limit the number of records to 10,000, the simplest way to export all of the index data as JSON file is to use the elasticsearch-dump tool: https://github.com/elasticsearch-dump/elasticsearch-dump.
Here's a new tool we've been working on for exactly this purpose https://github.com/taskrabbit/elasticsearch-dump. You can export indices into/out of JSON files, or from one cluster to another.

Elasticsearch supports a snapshot function out of the box:
