集群的 Elasticsearch 快照

Question

I have a Elasticsearch cluster running with three nodes. and have created a snapshot repository for the cluster, and trying to create a snapshot manually using,

10.0.0.120:9200/_snapshot/$REPO_NAME/$SNAPSHOT_NAME

But I am not sure if I have to create snapshot from all nodes or from any one node? And if i have to make snapshot call from all nodes seperately, should the name of snapshot be same?

Also is there a way to verify if the snapshot is fine without restoring it?

Answer 1

According to Documentation “A snapshot is a backup of a running Elasticsearch cluster.”

So all nodes will be in, and you don't need to make separate snapshots.
