AWS Glacier & Retention Policies

https://aws.amazon.com/blogs/aws/glacier-vault-lock/

For orgs that want to move AWS data (e.g., S3, EBS) to offline storage Glacier is the answer.

However, an org will want to set access controls and retention periods for the data "vaults" in Glacier.

Per the link above, one can do that via the API.  Note that the output screenshots show JSON.
