Backup/Restore Indexes

Elastic Stack Elasticsearch
1

Hey guys,

I have an Elasticsearch node in production and am experiencing issues regarding disk storage. At the moment I cannot increase computational resources or add other nodes because I depend on collaboration with another department in the company.

As a temporary measure to avoid stopping the cluster, can I somehow perform a backup/dump of some indexes to another server, and then restore them later?

The easiest way would be to create some snapshots on a cloud service and after that you could remove the local indices.

Using the Snapshot/Restore API is the only officially supported way of backup Elasticsearch data.

Here is the documentation.
