Elastic Frozen Storage

Elastic Stack Elasticsearch
1

Hello everyone,
a question regarding elastic architecture; I have 100 GB per day ingestion.
If I want to keep the data 300 days in a frozen node without any replication; how should I estimate the disk storage?

I don't have a license so I can't use searchable snapshots; so the estimate is simply 300 days x 100 GB?

Thank you very much.

If you are not using searchable shapshots there is nothing magic that reduces the size of data on disk as it moves from zone to zone, apart from posibly the number of replicas. Your calculation therefore seems reasonable.

As the snapshot api is available in the free tier. You can remove the replica shards. (deduplicating storage) and resulting in your calculation.

It is not as simple as 300*100 (because meta data, compression, shards, etc are a thing).
But for estimation yes.

To get closer to least amount of storage, you can also look at merging and closing your indices in the ILM policy. Could help.
