AWS Certified Data Analytics Specialty 2021 - Hands-On! - Amazon Simple Storage Service (Amazon S3) Versioning

The video tutorial explains how to enable and use versioning in Amazon S3. It covers the process of creating new file versions instead of overwriting existing ones, and highlights the benefits of versioning, such as protection against unintended deletions and the ability to restore previous versions. The tutorial also discusses important details like the 'null' version for files uploaded before versioning is enabled and the effects of suspending versioning. A hands-on demonstration is included to show how versioning works in practice.
