Versioning provides protection against overwrites and deletes by enabling you to preserve, retrieve, and restore every version of every object in an Amazon S3 bucket. Lifecycle rules provide you the ability to configure rules that define what automatically happens to objects stored in your buckets after a specific date or period of time.
Now that lifecycle rules are supported for versioning, you can combine versioning and lifecycle rules to enable scenarios such as easily setting up a rule that stores all your previous object versions in the lower cost Glacier storage class and deletes them from Glacier storage after 100 days. This example would provide a 100 day window to roll back any changes made to your data and automatically lower your storage costs.
