Elasticsearch - backup a cluster

[genseb]

Hi,

I have a 5 nodes cluster, behind a load balancer, that I want to backup.

I have 2 questions:

-Do I have to run my backup command (curl -XPUT "http://localhost:9200/_snapshot/s3_repository/snap1?wait_for_completion=true") on every node of the cluster to backup data or can I do it using my load balancer address (which will point to only one node of the cluster at a time)?

-Using my backup command (curl -XPUT "http://localhost:9200/_snapshot/s3_repository/snap1?wait_for_completion=true") will I be able to remount a new cluster if my cluster crashes without backuping anything else?

Thanks.

Snapshots happen on a cluster level, irrespective of which node you call to request it.

If you are unsure of the restore process, then why not give it a go

Thanks a lot for your answer.

Just like to be sure to start in the right way using snapshot.
