将Production Cloud数据存储区复制到Dev Server Datastore

Question

根据在线文档,为了备份数据,您必须在启用后转到数据存储管理员.它在我的生产服务器上启用.

要导入,只需再次转到管理页面,然后选择刚刚创建的后面名称.我已将我的Google Bucket备份下载到本地驱动器上,按照此处的便捷指南的所有步骤进行操作http://gbayer.com/big-data/app-engine-datastore-how-to-efficiently-export-您的数据/

既然我在本地拥有数据,那么我一直试图将它放入本地开发服务器.

appcfg.py upload_data --application=dev~<APP_ID> --url=http://localhost:8080/_ah/remote_api --filename=<lengthyfilename>.backup_info

    cursor.execute('select id, value from result')

在本地管理页面内,任何Cloud Datastore页面中都没有还原选项,我很茫然.我找到的所有答案都是五年之久,在过时的包装上.如何将Cloud Datastore Backup还原到Developer App Server？

使用数据存储模拟器的好处之一是它现在支持导入和导出。
