Last updated: 2024-03-25 14:38:14

    Overview

    This document describes how to restore a historical object version as the latest version in the COS console. For more information on versioning, see Overview.
    Note:
    Object restoration refers to restoring a historical object version as the latest one with the historical version retained.
    To delete a historical version, see Setting Versioning and Deleting Objects.
    Currently, you can only restore objects one by one instead of in batches.
