Elasticsearch SLM retention

Elastic Stack Elasticsearch

Hi All,

I have a question about the retention at SLM.
If I set a retention period for an SLM Policy, the SLM will deletes all the snapshots older then the retention period.
Since Elasticsearch is dealing with incremental snapshots how can I do a full restore (if the base snapshot is already deleted because of the retention settings)?
ES version: 7.13

Thanks.

Each snapshot is a full snapshot. The incremental aspect of it is that segments that have not changed between snapshots are reused and not copied multiple times.
