Restore Deleted S3 Objects: Versioned Buckets

You deleted an object from a production Amazon S3 bucket. The bucket enables versioning. This section explains how to retrieve the object.

Amazon S3 uses delete markers in versioned buckets. When you delete an object, S3 creates a delete marker. The marker becomes the current version. The original object becomes a previous version. S3 treats the object as deleted. GET requests return an error.

Update the script path to match your file location. Run the script.
