Elastic search has finally introduced snapshot this year, this tool is no longer supported

https://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-snapshots.html

This tool requires node.js and ElasticSearch.

Run this first:

$ npm install

Usage:

$ node index.js -h [host] -p [port] -i [index_name] -m [mapping] -f [file_name]

For exmaple

$ node index.js -h localhost -p 9200 -i big-data -m magic-cards -f test.json

Should backup the magic-cards into a file called "test.json"

when -i is not inputted, it will back up the entire database

$ node index.js

This will backup entire database into "backup.json"
