ElasticSearch Backup/Restore from S3

Steps to restore an ElasticSearch Snapshot from an S3 backup:

*make sure same version for less issues

1. Install S3 plugin

2. allow insecure settings (on local ElasticSearch instance)
   a. open ProgramData -> Elastic -> ElasticSearch -> config -> jvm.options
   b. edit the file and add the line "-Des.allow_insecure_settings=true" to the bottom.
   c. restart the ElasticSearch service.

3. Register the S3 bucket as a snapshot repository
   a. Do a PUT to "http://localhost:9200/_snapshot/s3_repository " with a body: {
   "type": "s3",
   "settings": {
   "bucket": "elasticsearch-monitor",
   "region": "us-east-1",
   "access_key": "{access_key}",
   "secret_key": "{key_secret}"
   }
   }

4. Create the snapshot
   a. Do a POST "http://localhost:9200/_snapshot/s3_repository/{snapshot_name}?wait_for_completion=true " with a body:
   {
   "type": "s3",
   "settings": {
   "bucket": "efc-elasticsearch-export",
   "region": "us-east-1",
   "access_key": "{access_key}",
   "secret_key": "{key_secret}"
   }
   }

5. Register S3 repository with hosted ElasticSearch: Following this article  or article2 
   a. Once you have the role arn and S3 access key and secret, do a PUT request to the AWS ElasticSearch instance using Postman.
   b. Postman has the ability to do a "Signed Request" which is important for this PUT request to complete successfully. You do this by going to the Authorization tab, selecting Type: AWS Signature. Enter the access key, and secret, region (probably us-east-1) and Service Name (es).
   c. The URL and body are as follows:
   URL: https://{your url}.us-east-1.es.amazonaws.com/_snapshot/s3_repository?pretty&verify=false
   Body (JSON): {
   "type": "s3",
   "settings": {
   "bucket": "efc-elasticsearch-export",
   "role_arn": "arn:aws:iam::{your arn}:role/es-to-s3-repository-staging-role",
   "region": "us-east-1"
   }
   }
   d. Validate snapshot is available: GET "https://{yoururl}.us-east-1.es.amazonaws.com/_snapshot/s3_repository/_all"
   e. Restore the snapshot with a POST "https://{your_url}.us-east-1.es.amazonaws.com/_snapshot/s3_repository/{snapshot_name}/_restore"
