我认为消息"创建数据库副本的权限不足"表示您没有权利创建复制操作，而不是创建数据库本身。使用
连接到目标服务器以运行命令的帐户也必须在源服务器上使用相同的用户名和密码。

I believe that the message "Insufficient permission to create a database copy " is indicating you don;t have hte right permissions to create the copy operation, not to create the DB itself. The account you connect to the destination server with to run the command must also exist on the source server with the same username and password.
