Important system indices

Hi All,

Struggling to find a post detailing important system indices that should be backed up. Can someone provide a list of what should be backed up?

My use case, is if our cluster was to corrupt, yes the data in it is a loss, but we can re-ingest start from scratch. What we can't start from scratch is all the visualisations, dashboards, searches and ingest pipelines.

I have noted i should backup .logstash and .kibana* but anything else?
