Elastic search has finally introduced snapshot this year, this tool is no longer supported
This tool requires node.js and ElasticSearch.
Run this first:
$ npm install
$ node index.js -h [host] -p [port] -i [index_name] -m [mapping] -f [file_name]
$ 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"
