Managing repositories

ElasticSearch provides a built-in system to quickly snapshot and restore your data. When working with live data, it's difficult to have a backup because of the large number of concurrency problems.

An ElasticSearch snapshot allows us to create snapshots of individual indices (or aliases), or an entire cluster, in a remote repository.

Before starting to execute a snapshot, a repository must be created.

Getting ready

You need a working ElasticSearch cluster.

How to do it...

To manage a repository, we will perform the following steps:

1. To create a repository called my_backup, the HTTP method is PUT and the curl command is:

   curl -XPUT 'http://localhost:9200/_snapshot/my_backup' -d '{
     "type": "fs",
     "settings": {
       "location": "/tmp/my_backup",
       "compress": true
     }
   }'
   

   The result will be:

   {"acknowledged":true}

   If you check on your filesystem, the directory /tmp/my_backup is created...
