Elasticsearch Backups

Guy Shilo shows how you can back up an Elasticsearch cluster:

Elasticsearch is facing the same challenge and it’s built-in backup method is snapshots. Unlike classic storage snapshots, Elasticsearch snapshot can be stored remotely on external storage systems, and that is supposed to enable them deal with large amounts of data.

Snapshots can be stored on a shared file system (mounted on all cluster nodes), on all major cloud storage providers (Amazon S3, Azure and GCS) and on HDFS.

The documentation can be found here.

Read on to see the demo. Even if your Elasticsearch data is not the home of record and you could rebuild the cluster doesn’t mean ignoring backups is wise.
