POST Object restore

마지막 업데이트 시간:2024-06-12 15:10:38

    Feature Description

    The POST Object restore API allows you to send a request to restore an ARCHIVE/DEEP ARCHIVE object so that you can read it. The restored readable object is a temporary copy, for which you can set the readable status and the time to delete it through the Days parameter. If the time has elapsed and you haven't initiated a copy or extension operation, the temporary object will be automatically deleted. Temporary objects are only copies of the archived objects which always exist. For more information on the ARCHIVE storage class, see Overview.
    Note:
    The QPS of the POST Object restore API is limited to 100.
    

    Versioning

    If versioning is enabled, you can use the versionId parameter in your request to specify the ID of the version to be restored. If this parameter is not specified, the latest version will be restored.
