This API allows you to send a request to restore an ARCHIVED/DEEP ARCHIVED object so that you can read it. The restored readable object is a temporary copy, for which you can set "Keep Readable" and the time at which to delete it at a later point. You can use the "Days" parameter to specify the expiration time of the temporary object. If the time is exceeded and you haven’t initiated a copy, extension, or any other operation, the temporary object will be automatically deleted. Temporary objects are only copies of the archived objects which always exist. For more information about ARCHIVE, please see Storage Class Overview- ARCHIVE.
If versioning is enabled, you can use the versionId parameter in your request to specify the ID of the version to restore. If not specified, the latest version will be restored.
