亲爱的Praveen，

SAP没有实现灾难恢复解决方案的"最佳实践"之类的文档，而"灾难恢复"则让人联想到业务连续性，数据和数据库恢复，网络和服务器可用性，员工的想法 专业知识/培训/可用性以及政策和程序。 因此，灾难恢复计划涉及很多变量。

有关更多信息，我建议您的团队根据Microsoft参考资料进行审查：

https://docs.microsoft.com/zh-CN/sql/database-engine/sql-server-business-continuity-dr?view=sql-server-2017

http://blogs.technet.com/b/minutes_on_bi/archive/2010/09/20/ sql-server-sap-deployment在qr的技术案例研究.aspx的高可用性和灾难恢复

关于Microsoft SQL Server AlwaysOn，我们建议SAP客户检查并依赖以下SAP注释：

1772688-SQL Server AlwaysOn和SAP应用程序
