unable to backup elastic search data?

Hi I am having an elastic search (version 6.6.0) running on a machine . It has some indexes .

curl -X GET "10.10.9.1:9200/_cat/indices/mep-reports*?v&s=index&pretty"
health status index                  uuid                   pri rep docs.count docs.deleted store.size pri.store.size

I would like to take a data backup and populate that in my local elastic search instance. for that i have tried the following

curl -X PUT "10.10.9.1:9200/_snapshot/my_backup?pretty" -H 'Content-Type: application/json' -d'
{
  "type": "fs",
  "settings": {
    "location": "/tmp/es-backup"
  }
}'

it then returns

{
  "acknowledged" : true
}

how ever when i tries to list the back up folder it is empty .

ls -ltra /tmp/es-backup
total 4
drwxrwxrwt 1 root root 4096 Feb 12 11:11 ..
drwxrwxr-x 2 omn  omn     6 Feb 12 11:46 .

really appreciate any help

thank you

Solution

Try to use elasticdump to transfer data from one elastic to another.

You can also output your data into a .json file.

A working example:

Export your indices (data) from a remote elastic server to a .json file.

elasticdump --input=http://10.10.9.1:9200 --output=data.json --type=data

Import data.json (located in your local machine) to your local elastic server.

elasticdump --input=data.json --output=http://localhost:9200 --type=data

Try it.

Hope this helps
