Hi All, I was wondering if it's possible to create snapshot policies that include/exclude indices based on their phase? I wasn't able to find any documentation on this and didn't see any posts about it. The use case I am interested in is the following: Have two (2) S3 repositories: - S3\_Repo\_A is on-prem and has a 25Gbps connection to the cluster - S3\_Repo\_B is in the cloud and has a 1Gbps connection to the cluster I would like to back up all indexes that match the pattern `index-*` (can also be a data stream) It order to meet Mean Time To Recovery (MTTR) I'd like to have three (3) snapshot policies setup. 1. SLM\_Policy\_Hourly\_Hot: - Hourly snaphot of `index-*` WHERE index phase is hot - S3 Repo: S3\_Repo\_A 2. SLM\_Policy\_Daily\_Warm: - Daily snapshot of `index-*` WHERE index phase is warm - S3 Repo: S3\_Repo\_A 3. SLM\_Policy\_Daily\_Cold: - Daily snapshot of `index-*` WHERE index phase is cold - S3 Repo: S3\_Repo\_B Is the above currently possible? ---

I don't think you can, but I also don't really understand the advantages of this scheme over simply snapshotting everything hourly into `S3_Repo_A` and daily into `S3_Repo_B`. Can you explain your thinking a bit more clearly? ---

Yes, for a bit more clarity, S3\_Repo\_A has limited storage available to it, and does not have the required space needed to back up everything in `index-*`. So while policies 1 and 2 could be merged, policy 3 wouldn't be able to. The cold phase will hold the majority of data, and therefore needs to be offloaded to S3\_Repo\_B. ---

Thanks, I see. I guess we generally expect that every repository is at least as big as the cluster to which it's attached but that isn't the case for you. An interesting idea for sure, but no I don't think it's possible today. ---

Thanks for the information @DavidTurner. Would this make a good feature request for Elasticsearch, or do you think it's something that won't be supported? ---

> [@BenB196](#): > > Would this make a good feature request for Elasticsearch, or do you think it's something that won't be supported? Seems like a reasonable request, but we're not exactly short of those 😉 It might not happen any time soon, unless it turns out to be a very popular idea. ---
