在 Compute Engine 執行個體上,適用於 SAP HANA 的 SAP HANA savepoint API (永久磁碟快照)
備份和 DR 會使用永久磁碟快照,以增量方式備份永久磁碟中的資料和記錄磁碟區,並維持應用程式一致性。備份和 DR 會將每個快照的多個副本儲存在不同位置,同時也會自動使用檢查碼機制確保資料完整性。備份和 DR 服務支援 SAP HANA 2.0 向上擴充和 SAP HANA 2.0 HA (1+1) 複製系統。
SAP HANA savepoint API (磁區層級備份)
這種方法會根據儲存在資料卷區和 Linux 變更區塊追蹤中的儲存點,運用 SAP HANA 資料庫內部快照,以便取得有效、節省空間的增量永久備份。
SAP HANA 資料會根據指定的備份計畫,以應用程式優先格式擷取。系統會建立並儲存該資料的黃金副本,然後以增量永久模型中僅含有變更資料區塊的形式,以增量方式更新該副本。這可讓您立即掛載及復原 SAP HANA 資料庫。資料的虛擬副本可立即供使用,無須大量複製實體副本,也不必占用額外的儲存基礎架構。
SAP Backint API (完整 + 增量備份)
備份 SAP HANA 的舊版方式是使用 Backint API 和 hdbsql。Backint API 會透過 iSCSI 或 NFS 將備份資料傳送至已對應至 SAP HANA 主機的暫存磁碟。無論採用哪種方法,都會定期執行完整備份作業,且擷取的資料採用專屬備份格式,而非區塊格式。

For Scale-Up and HA 1+1 configurations, see [Backup and DR Service for SAP HANA](/backup-disaster-recovery/docs/concepts/backupdr-for-sap-hana).\n\nProtection methods\n------------------\n\nThe most common protection method for SAP HANA databases and logs in\nBackup and DR is the SAP HANA `savepoint` API (Persistent Disk snapshot)\nfor SAP HANA on a Compute Engine instance.\n\nYou can also protect HANA databases using either of the two following alternative\nprotection methods:\n\n- SAP HANA `savepoint` API (LVM backup)\n- SAP `backint` API (Full+Incremental backup)\n\nThese methods are preferable only if you require HANA Scale-Out or if you have\nneed for application-aware mounts or mount-and-migrate ability for HANA\ndatabases.\n\nIf you can use the Persistent Disk snapshot backup method, then go to [Backup and DR Service for SAP HANA](/backup-disaster-recovery/docs/concepts/backupdr-for-sap-hana).\n\n### SAP HANA `savepoint` API (Persistent Disk snapshot) for SAP HANA on a Compute Engine instance\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.\n\n### SAP HANA `savepoint` API (volume-level backup)\n\nThis method leverages an SAP HANA database internal snapshot based\non savepoint stored in the data volumes area and in Linux change block tracking\nto take an efficient, space saving, incremental forever backup.\n\nSAP HANA data is captured in application first format, according to a specified\nbackup plan. A golden copy of that data is created and stored once, and is then\nupdated incrementally with only the changed blocks of data in an incremental\nforever model. This provides the advantage of instantaneous mount and recovery\nof SAP HANA databases. Virtual copies of the data can be made available\ninstantly for use, without proliferating physical copies and taking up\nadditional storage infrastructure.\n\n### SAP `Backint` API (Full+Incremental backup)\n\nThe older way of backing up SAP HANA is using the Backint API using\nhdbsql. The Backint API sends backups to a staging disk mapped to the SAP HANA\nhost over iSCSI or NFS. In both approaches, there is a periodic full backup and\nthe data captured is in a proprietary backup format and not in block\nformat.\n\n### Backup and DR supportability of different SAP HANA configurations\n\n| **Note:** See the important information at [SAP HANA studio, metadata, and backup images](/backup-disaster-recovery/docs/access-data/recover-sap-hana#SAP-HANA-studio,-metadata,-and-backup-images).\n\nBackup and DR can virtualize and protect the following:\n\n- **Single container system (HANA 1.0 or 2.0) dedicated**: In a\n single-container system the system database and tenant database are seen as a\n single unit and are administered as one.\n\n- **Multiple-container systems (HANA 2.0)**: Multiple isolated databases in a\n single SAP HANA system. These are referred to as multi-tenant database\n containers. A multiple-container system always has exactly one system\n database used for central system administration, and any number of\n multi-tenant databases (including zero), also called tenant databases.\n\nThis table lists all the supported HANA configurations and the backup methods\nthat apply with each one.\n\n- HANA `SavePoint` API method is the preferred method when available, for all HANA\n configurations except for scale-out with shared storage.\n\n- The `backint` method is available for all HANA configurations.\n\n- HANA log backups are always handled automatically for all configurations and\n options.\n\nWhat's next\n-----------\n\n[Prepare the database for Backup and DR](/backup-disaster-recovery/docs/configuration/prepare-sap-hana-scaleout)\n\nBackup and DR Service documentation for SAP HANA Scale-Out\n----------------------------------------------------------\n\nThis page is one in a series of pages specific to protecting and recovering\nSAP HANA Scale-Out instances with Backup and DR Service.\nYou can find additional information in the following pages:\n\n- [Backup and DR for SAP HANA Scale-Out](/backup-disaster-recovery/docs/concepts/backupdr-for-sap-hana-scaleout)\n- [Prepare SAP HANA Scale-Out instances for backup](/backup-disaster-recovery/docs/configuration/prepare-sap-hana)\n- [Add an SAP HANA Scale-Out host, and discover and protect its databases](/backup-disaster-recovery/docs/configuration/discover-sap-hana-scaleout)\n- [Configure staging disk format and backup method for SAP HANA Scale-Out](/backup-disaster-recovery/docs/backup/backup-method-staging-disk-sap-hana-scaleout)\n- [Set application details and settings for SAP HANA Scale-Out instances](/backup-disaster-recovery/docs/backup/app-details-settings-sap-hana-scaleout)\n- [Back up HANA 1+n and HANA scale-out databases](/backup-disaster-recovery/docs/backup/back-up-sap-hana-scaleout)\n- [Restore and recover SAP HANA Scale-Out instances](/backup-disaster-recovery/docs/restore-data/restore-sap-hana-scaleout)\n- [Mount an SAP HANA Scale-Out backup as a standard mount](/backup-disaster-recovery/docs/access-data/mount-sap-hana)\n- [Mount an SAP HANA Scale-Out backup as a virtual database](/backup-disaster-recovery/docs/access-data/mount-sap-hana-virtualdb)\n- [Mount and migrate an SAP HANA Scale-Out backup for instant recovery to any target](/backup-disaster-recovery/docs/access-data/mount-and-migrate-sap-hana)"]]
