Versioning

S3 allows you to keep multiple versions of an object in a bucket. Versioning can be enabled at bucket level. Once versioning is enabled, it protects you from accidental updates and deletes on an object. When you overwrite or delete an object, it keeps multiple copies with version numbers.

For example, when you enable versioning on a bucket called packtpub, for each action on an existing object in the bucket, S3 creates a new version and associates a version ID with it, as shown in the following table:

Object

Last activity

Version ID
