Question

当我尝试通过Azure门户中的“导出”按钮导出数据库时，出现以下错误：

Error encountered during the service operation. 
Could not extract package from specified database. 
The element DataSyncEncryptionKey_8d263adb59574052847134070b69d73d is not supported in Microsoft Azure SQL Database v12.

尽管我曾经尝试过DataSync服务，但我从未最终使用过它，现在肯定不使用它。我什至后悔尝试该服务，因为它在数据库中创建了我不知道如何完全删除的架构。

现在，这些模式似乎阻止了我导出数据库。

至少可以很好地解决此错误。但是，最好删除所有DataSync服务的痕迹。

请注意，我已经在以下问题的可接受解决方案中使用了脚本：How to remove SQL Azure Data Sync objects manually。那删除了DataSync模式，但我仍然剩下'dss'和'TaskHosting'模式。

我还尝试了电子邮件支持，这是该线程https://social.msdn.microsoft.com/Forums/azure/en-US/8b68b44b-c98a-4b38-8aab-36a30a7fafd9/the-element-datasyncencryptionkeyid-is-not-supported-in-microsoft-azure-sql-database-v12-when?forum=ssdsgetstarted中公认的解决方案所建议的。那封电子邮件只是反弹了。

此外，如果我进入Azure门户，它将不会显示任何同步组或同步代理。

Answer 1

我希望您在继续执行在不存在SQL Data Sync 2.0时创建的那些旧论坛线程上概述的步骤之前，已经问过这个问题。 SQL Data Sync不再处于预览状态，本月进入GA并提供了一个deprovision实用程序。

在安装SQL Agent的计算机上的c：\ program files（x86）\ Microsoft SQL Azure Data Sync目录下，您应该找到一个名为deprovisionUtil.exe的实用程序。如果使用开关/ F运行它，它将删除DSS架构及其所有对象。

如果现在无法实现，请创建支持记录。 Azure支持将清理同步数据库。

首先，让我感谢@ alberto-morillo的帮助。如果情况有所不同，SQL代理很有可能会工作。

最后，我联系了Azure支持，他们给了我以下脚本。之后一切正常。
