In OSS, what does enabling versioning do for objects?

Enabling versioning in Alibaba Cloud's Object Storage Service (OSS) is a feature that allows users to retain all versions of an object whenever it is modified or deleted. This means that every time you upload a new version of an object, the previous versions are kept in the storage, thereby providing a way to recover any prior version if needed. This is particularly useful for scenarios where changes need to be rolled back or previous states of an object are required for auditing or operational reasons.

However, it is important to note that with versioning enabled, each version of the object is treated as a separate entry in storage. This means that while you gain the ability to access previous versions, this also leads to increased storage consumption, which subsequently incurs additional costs. Users need to manage storage accordingly to keep their costs in check while taking advantage of the versioning feature.

In contrast, the other options presented do not accurately describe the implications of enabling versioning within OSS. For example, it does not eliminate the need for object deletion, nor does it automatically promote the latest version. While it does allow for unlimited storage for all versions, it's important to recognize that additional costs are a significant consideration that comes with retaining those versions. Thus, the key aspect of enabling version
