Backup and restore data

All persistent data are stored in ElasticSearch database. The backup and restore procedures are the ones that are detailed in ElasticSearch documentation.

Note: you may have to adapt you indices in the examples below. To find the right indice, use the following command :

curl 'localhost:9200/_cat/indices?v'

1. Create a snapshot repository

First you must define a location in local filesystem (where ElasticSearch instance runs) where the backup will be written. Be careful if you run ElasticSearch in Docker, the directory must be mapped in host filesystem using --volume parameter (cf. Docker documentation).

Create a ElasticSearch snapshot point with the following command :

$ curl -XPUT 'http://localhost:9200/_snapshot/the_hive_backup' -d '{
    "type": "fs",
    "settings": {
        "location": "/absolute/path/to/backup/directory",
        "compress": true
    }
}'

2. Backup your data

Start the backup by executing the following command :

$ curl -XPUT 'http://localhost:9200/_snapshot/the_hive_backup/snapshot_1' -d '{
  "indices": "the_hive_10"
}'

You can backup the last index of TheHive (you can list indices in you ElasticSearch cluster with curl -s http://localhost:9200/_cat/indices | cut -d ' ' -f3 ) or all indices with _all value.

3. Restore data

Restore will do the reverse actions : it reads backup in your snapshot directory and load indices in ElasticSearch cluster. This operation is done with this command :

$ curl -XPOST http://localhost:9200/_snapshot/the_hive_backup/snapshot_1/_restore
{
  "indices": "the_hive_10"
}
