SAP HANA 是世界上最受欢迎的企业数据库之一。它之所以独特，是因为它在内存中运行，因此可以非常快速地返回查询结果。许多企业都将 SAP HANA 用于关键任务型应用。与任何数据库一样，SAP HANA 也容易出现损坏、意外删除，甚至勒索软件攻击等安全威胁。借助备份和灾难恢复服务，您可以高效且安全地备份和恢复生产系统。
保护 SAP HANA 数据库
在备份和灾难恢复中，建议为 SAP HANA 数据库和日志采用的保护方法是 SAP HANA savepoint API（Persistent Disk 快照）。
Backup and DR Service 使用 Persistent Disk 快照以增量方式备份永久性磁盘中的数据和日志卷，并确保应用一致性。备份和灾难恢复在多个位置存储每个快照的多个副本，并利用自动校验和来确保数据完整性。Backup and DR 支持 SAP HANA 2.0 扩容和 SAP HANA 2.0 高可用性 (1+1) 复制系统。永久性磁盘快照不支持 HANA 横向扩容。
保护 SAP HANA 横向扩容实例
尚不支持使用永久性磁盘快照保护 HANA 横向扩容实例。您可以使用以下两种替代保护方法保护 HANA 横向扩容实例：
