Restoring an OpenSearch Cluster from a Backup

Option 1. Restore the backup to the source cluster 🔗

With this option, you revert the data in an existing cluster to a snapshot from a previous point in time. The backup can only be restored to the source, you can't select another cluster to restore the backup to. Use this option when the cluster is fine, but there's an issue with the data in a cluster, so you want to restore the data only. See Restoring a Backup to the Source OpenSearch Cluster.

Option 2. Restore the backup to a new cluster 🔗

With this option, you restore the backup to a different cluster. Before you restore the backup, you need to create the new cluster. Follow the steps in Creating an OpenSearch Cluster, and specify the name node configuration options as the ones for the cluster you're restoring from backup.

Use this option when the cluster itself has failed and you need to rebuild the cluster. See Restoring a Backup to a New OpenSearch Cluster.
