Taking a snapshot of one Elasticsearch cluster and restoring it to another
Important
Elasticsearch is only supported up to version 6.8, which is no longer supported by Elastic. We therefore recommend using Storage as a Service instead, or if you do want to continue using self-hosted storage, using OpenSearch.
The procedure details how you can take and restore snapshots to back up and restore Elasticsearch data. See the documentation on taking and restoring snapshots.
Note
We recommend that you use a Linux system when following this guide. However, it is also applicable to a Windows setup.
Prerequisites
- Elasticsearch knowledge
- A client application that is able to communicate with the Elasticsearch rest API, e.g. Kibana
- A target Elasticsearch cluster of the same or a more recent version than the source Elasticsearch cluster
- A high-quality connection between the Elasticsearch clusters
Procedure
Follow the procedure included in the documentation on configuring multiple Elasticsearch clusters.
