@JohnathonBowers,

I am not pretty sure if your changes are correct. The person how brought the issue specifically refers to take out the Snapshot Management feature (check the issue again).

I think what he is asking is to get rid of the section Snapshot Management API on the documentation. However, I am not an expert neither in OpenSearch v1.3 nor v2.1. What I suggest you is to ask setiah
Himanshu Setia what specifically is the request. Or instead, ask the main maintainers of OpenSearch for help (there is a group in Slack called core where everything about OpenSearch backbone is talked about).

Regards,

Samuel

@JohnathonBowers: @BigSamu is correct. We need only to remove this page: https://github.com/opensearch-project/documentation-website/blob/1.3/_tuning-your-cluster/availability-and-recovery/snapshots/sm-api.md.

All other APIs and Snapshot information should still be relevant to 1.3.

Thank you, @BigSamu and @Naarcha-AWS , for the feedback. I undid the changes I had made and then made a new commit with only the sm-api.md file removed. Below is a screenshot of the documentation website before this most recent change:

And here is a screenshot of the website after the change, showing that the Snapshot management API page has been removed:
