can someone please help me understand this: [Data tiers | Elasticsearch Guide [8.17] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/data-tiers.html#cold-tier)

It says:  
1/ cold tier uses searchable snapshots  
2/ it can also be used with a replica

How do I implement this in self managed cluster? I can reserve a HDD storage for cold tier. But without replica how do I ensure there is no data loss. What could I do so data is read from searchable snapshots?

Please advise
