I have a ES 2.2.x cluster with dedicated data, master and client nodes. Master nodes manage the cluster metadata, but where do they persist it? (i.e. where is it stored if I gracefully shutdown all of the nodes) Thanks, Zaar

Where cluster metadata is stored?

I did some testing here. While ES was able recover "dangling" indexes and transient settings just fine, this is only one simple scenario that I have tested.

Do I need to backup cluster global metadata?
