Versioning and Locking

Return to table of contents
Exam Tips:
- Versioning:
  - Cannot disable versioning, can only suspend.
  - Unique ID per object, and with versioning a new unique ID is added for object per each new version.
  - If an object is deleted when versioning is enabled, it adds a delete marker, but does not delete the object itself or versions of the object.
    - Can delete the delete marker to see the object again in the console and cli.
  - Be aware that versioning exists and that you can refer to previous versions.
- Object Locking:
  - Needs versioning enabled as well.
  - Can only be enabled at the time of creating a bucket.
    - Requires a support ticket to enable on existing buckets.
