Welcome to the lesson on mastering file versioning and management in Amazon S3 with Boto3. Versioning in Amazon S3 acts as a safeguard for your data, protecting against accidental overwrites or deletions by keeping multiple versions of an object, similar to maintaining various drafts of a document. Each update creates a new, retrievable version, ensuring no data is lost unintentionally.

Throughout this lesson, we will explore how to enable, utilize, and effectively manage versioning in your S3 buckets using the Boto3 SDK. This feature is crucial for maintaining data integrity and recoverability, especially in applications requiring rigorous backup solutions or historical data retention.

To activate versioning for a S3 bucket, you can use the Boto3 library. The Python code below shows you how to turn on versioning for a bucket named my_bucket.

Another important aspect of managing your S3 bucket is the ability to suspend versioning. It's crucial to understand that once versioning is enabled on a bucket in Amazon S3, it cannot be fully disabled. However, you can suspend versioning, which stops S3 from assigning new version IDs to objects. This means that while objects already stored in the bucket retain their version IDs, any new uploads or modifications will not create new versions but will instead overwrite the current version if versioning is suspended.

To suspend versioning on a bucket with Boto3, you can use the following code snippet:
