Last updated: 2022-05-06 17:10:59

    Overview

    This document describes how to restore a historical version as the latest version via the COS console. For more information about versioning, please see Versioning 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, please see Setting Versioning and Deleting an Object.
    • Currently, you can only restore objects one by one instead of in batches.

    Instructions

    The following describes the scenarios and rules for object restoration.

    • Scenarios:

      • Versioning-enabled buckets support object restoration.。
      • If versioning is enabled and then disabled for a bucket, object restoration is not supported.
