Snapshots

Snapshots are backups of a cluster's indexes and state. State includes cluster settings, node information, index metadata (mappings, settings, or templates), and shard allocation.

Snapshots have two main uses:

  • Recovering from failure

    For example, if cluster health goes red, you might restore the red indexes from a snapshot.

  • Migrating from one cluster to another

    For example, if you're moving from a proof-of-concept to a production cluster, you might take a snapshot of the former and restore it on the latter.

You can take and restore snapshots using the snapshot API.

If you need to automate snapshot creation, you can use the snapshot management feature.
