我试图将数据从 RDS 移动到 S3 作为备份。我在本地电脑上使用 DBeaver 与 AWS RDS 建立连接并上传了一个 csv 文件。
然后，我尝试创建一个数据管道以将数据从 RDS 发送到 S3。最初，我收到一个错误DBInstance not found.但是，当我在“Edit Architect”中提供 DBInstance 区域时，因为它与 Data Pipeline 的区域不同，现在，我没有收到该错误。
相反，我得到了一个不同的错误；错误编号：ActivityFailed:SocketTimeoutException
error message: connect timed out
