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：

It's\nunique because it runs in-memory, so it can return query results very quickly.\nMany enterprises use SAP HANA for their mission critical applications. As can\nhappen with any database, SAP HANA is susceptible to corruption, accidental\ndeletion, or even security threats such as ransomware attacks. Backup and DR Service\nlets you efficiently and securely back up and recover your production systems.\n\nProtecting SAP HANA databases\n-----------------------------\n\nThe recommended protection method for SAP HANA databases and logs in\nBackup and DR is the SAP HANA `savepoint` API (Persistent Disk snapshots).\n\n**To get started** protecting your HANA databases, go through the SAP HANA procedures in\n[Protect and recover an SAP HANA database running in Compute Engine](/backup-disaster-recovery/docs/quickstarts/sap-hana-on-gce-backup-recovery)\n\nBackup and DR uses Persistent Disk snapshots to incrementally back up data\nand log volume from your persistent disks with application consistency.\nBackup and DR stores multiple copies of each snapshot across multiple\nlocations with automatic checksums to ensure the integrity of your data.\nBackup and DR supports SAP HANA 2.0 Scale-up and SAP HANA 2.0 HA (1+1)\nreplication system. HANA Scale-Out is not supported for persistent disk snapshots.\n\n### Protecting SAP HANA Scale Out instances\n\nProtection of HANA Scale-Out instances with persistent disk snapshots is not\nyet supported. You can protect HANA Scale-Out instances using either of the two\nfollowing alternative protection methods:\n\n- SAP HANA `savepoint` API (LVM backup)\n- SAP `backint` API (Full+Incremental backup)\n\nThese methods are preferable only if you have HANA Scale-Out instances.\nIf you must use one of these alternative methods, see\n[Backup and DR for SAP HANA Scale-Out](/backup-disaster-recovery/docs/concepts/backupdr-for-sap-hana-scaleout).\n\nWhat's next\n-----------\n\nGo through the SAP HANA quick start exercise in\n[Protect and recover an SAP HANA database running in Compute Engine](/backup-disaster-recovery/docs/quickstarts/sap-hana-on-gce-backup-recovery)"]]
