[root@i-vvxxxxswtw5ne ~]# elasticdump --help elasticdump: Import and export tools for elasticsearch version: 2.2.0 Usage: elasticdump --input SOURCE --output DESTINATION [OPTIONS] --input Source location (required) --input-index Source index and type (default: all, example: index/type) --output Destination location (required) --output-index Destination index and type (default: all, example: index/type) --limit How many objects to move in batch per operation limit is approximate for file streams (default: 100) --debug Display the elasticsearch commands being used (default: false) --type What are we exporting? (default: data, options: [data, mapping]) --delete Delete documents one-by-one from the input as they are moved. Will not delete the source index (default: false) --searchBody Preform a partial extract based on search results (when ES is the input, (default: '{"query": { "match_all": {} } }')) --sourceOnly Output only the json contained within the document _source Normal: {"_index":"","_type":"","_id":"", "_source":{SOURCE}} sourceOnly: {SOURCE} (default: false) --all Load/store documents from ALL indexes (default: false) --ignore-errors Will continue the read/write loop on write error (default: false) --scrollTime Time the nodes will hold the requested search in order. (default: 10m) --maxSockets How many simultaneous HTTP requests can we process make? (default: 5 [node <= v0.10.x] / Infinity [node >= v0.11.x] ) --timeout Integer containing the number of milliseconds to wait for a request to respond before aborting the request. Passed directly to the request library. Mostly used when you don't care too much if you lose some data when importing but rather have speed. --offset Integer containing the number of rows you wish to skip ahead from the input transport. When importing a large index, things can go wrong, be it connectivity, crashes, someone forgetting to `screen`, etc. This allows you to start the dump again from the last known line written (as logged by the `offset` in the output). Please be advised that since no sorting is specified when the dump is initially created, there's no real way to guarantee that the skipped rows have already been written/parsed. This is more of an option for when you want to get most data as possible in the index without concern for losing some rows in the process, similar to the `timeout` option. --inputTransport Provide a custom js file to us as the input transport --outputTransport Provide a custom js file to us as the output transport --toLog When using a custom outputTransport, should log lines be appended to the output stream? (default: true, except for `$`) --help This page Examples: # Copy an index from production to staging with mappings: elasticdump \ --input=http://production.es.com:9200/my_index \ --output=http://staging.es.com:9200/my_index \ --type=mapping elasticdump \ --input=http://production.es.com:9200/my_index \ --output=http://staging.es.com:9200/my_index \ --type=data # Backup index data to a file: elasticdump \ --input=http://production.es.com:9200/my_index \ --output=/data/my_index_mapping.json \ --type=mapping elasticdump \ --input=http://production.es.com:9200/my_index \ --output=/data/my_index.json \ --type=data # Backup and index to a gzip using stdout: elasticdump \ --input=http://production.es.com:9200/my_index \ --output=$ \ | gzip > /data/my_index.json.gz # Backup the results of a query to a file elasticdump \ --input=http://production.es.com:9200/my_index \ --output=query.json \ --searchBody '{"query":{"term":{"username": "admin"}}}' Learn more @ https://github.com/taskrabbit/elasticsearch-dump
