AWS Certified Data Analytics Specialty 2021 – Hands-On - S3 Versioning

The video tutorial discusses Amazon S3 versioning, explaining how files can be versioned once enabled at the bucket level. It highlights that re-uploading a file with the same key creates a new version rather than overwriting the existing one. The tutorial emphasizes the benefits of versioning, such as protection against unintended deletions and the ability to restore previous versions. It also covers important considerations, like the 'null' version for files uploaded before enabling versioning and the impact of suspending versioning.
