AWS aws-backup documentation change

Service: aws-backup · 2025-11-19 · Documentation low

File: aws-backup/latest/devguide/doc-history.md

Summary

Updated API version dates, added backup tiering documentation, and standardized 'CloudFormation' terminology

Security assessment

While backup tiering introduces new storage options, the documentation change only announces availability without detailing security implications. Terminology updates are non-security related.
