所有已配置的服务（请参阅 SAP 备注 1697613 和 SAP 备注 1649519），例如 nameserver 和 indexserver。必须处于运行状态。您可以在 SAP HANA Studio 的“Overview”>“Operational State”>“Confirm all services are started”中进行检查。
如需允许备份和灾难恢复代理执行主机端操作，请使用 SAP HANA hdbuserstore 密钥（而非用户名和密码）通过 SAP HANA 安全用户存储区与 HANA 数据库通信。请参阅配置 HANA Userstore 密钥。
如果 SAP HANA 的底层数据卷使用 LVM 快照（已集成 CBT）或与 backint 集成的基于文件的备份作为 SAP HANA 数据库备份进行保护，并且您还要保护同一主机上的文件系统，则应在文件系统应用中将 /hana/log 和 /hana/data 设置为排除路径。请参阅 Linux 文件系统。
HANA 归档日志备份建议：
请务必将 HANA 归档日志备份路径设置为 global.ini 中的 basepath_logbackup 和 basepath_catalogbackup。
Backup and DR 代理是 SAP HANA 服务器上占用空间小且轻量级的服务，用于捕获 SAP HANA 数据库的应用一致副本。它使用更改块跟踪功能来识别数据库数据的更改，以便备份和灾难恢复的增量永久捕获策略。所有包含需要由备份和灾难恢复服务保护的数据的 SAP HANA 服务器都必须安装备份和灾难恢复代理。

Before you begin, be sure to follow these\npreparation steps.\n| **Note:** This information is for SAP HANA scale-out instances. 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\nPrerequisites\n-------------\n\nBefore you begin, it's a good idea to review [Backup and DR for SAP HANA scale-out](/backup-disaster-recovery/docs/concepts/backupdr-for-sap-hana-scaleout).\n\n- All the configured services---see SAP Note 1697613 and SAP Note 1649519---\n such as `nameserver` and `indexserver`. must be running. You can check\n this in the Overview of SAP HANA studio \\\u003e Operational State \\\u003e\n Confirm all services are started.\n\n- To allow the Backup and DR agent to perform host-side operations, use an SAP\n HANA `hdbuserstore` key instead of a username and password to communicate with\n HANA database using the SAP HANA secure userstore. See [Configure the HANA userstore key](/backup-disaster-recovery/docs/configuration/prepare-hana#configuring_the_hana_userstore_key).\n\n- Database `log_mode` must be set to **normal** under the HANA Studio\n configuration tab. See [Set up the log mode and log backup in HANA Studio](#set-up-hana-log-mode).\n\n- All SAP HANA servers that have HANA data to be protected by Backup and DR Service\n must have been onboarded to Backup and DR Service.\n\n- All SAP HANA servers that have data to be protected by Backup and DR Service must\n [have the Backup and DR agent installed](#install-agent).\n\n- If the underlying data volumes for SAP HANA are protected as SAP HANA database\n backups using LVM snapshot with CBT or file-based backup integrated with\n `backint`, and if you are also protecting file systems on the same host, in\n the file system app, you should set `/hana/log` \\& `/hana/data` in an exclude\n path. See [Linux file system](/backup-disaster-recovery/docs/configuration/add-linux-hosts).\n\n- HANA Archive log backup recommendation:\n\n - Make sure to set the HANA Archive log backup path as the `basepath_logbackup` and `basepath_catalogbackup` in global.ini.\n - Don't use HANA Archive log mount to store files other than HANA Archive log backup.\n - By default, archive purge runs with every database backup. To achieve best recovery RTO, keep the default setting.\n\n| **Note:** If production log retention is set, then purge runs based on the **Retention of production db logs in hour** setting under Application Details \\& Settings. Size the HANA archive log backup disk to store archives based on the production log retention setting.\n\nConfigure the HANA userstore key\n--------------------------------\n\n| **Note:** This procedure requires the hostname.\n\nUse the following instructions to configure the HANA userstore key:\n\n1. Create the database backup user from HANA Studio.\n\n2. Get the instance and SQL port numbers.\n\n3. Create the SAP HANA `hdbuserstore` key for system DB backup users.\n\n### Step 1: Create the database backup user from HANA Studio\n\nChoose a database username based on the company's standard. Make sure to create\nthis user account under `SYSTEMDB`.\n\n1. Create the user under `SYSTEMDB`\n\n - From SAP HANA Studio SYSTEMDB, go to **System** \\\u003e **Security**\n \\\u003e **Users** \\\u003e **New User**.\n\n - Assign a username and a password.\n\n - Set **Force password change on next logon** to **No**.\n\n - Click the **System privilege tab** and assign privileges by\n selecting the following:\n\n ### HANA 1.0\n\n - **Backup admin**\n - **Catalog read**\n - **Database admin**\n\n ### HANA 2.0 (SPS01-SPS04)\n\n - **Backup admin**\n - **Catalog read**\n - **Database admin**\n - **Database start**\n - **Database stop**\n\n ### HANA 2.0 (SPS05)\n\n - **Backup admin**\n - **Catalog read**\n - **Database backup operator**\n - **Database recovery operator**\n - **Database admin**\n - **Database start**\n - **Database stop**\n2. Deploy the newly created system user by clicking the **green arrow**.\n\n### Step 2: Get the instance and SQL port numbers\n\nYou need the HANA instance and SQL port numbers for system databases. \n\n### HANA 1.0\n\nThe following instructions describe how to get the instance and SQL port\nnumbers from a HANA 1.0 single container system:\n\n1. Go to **System**.\n\n2. Click the **Landscape** tab.\n\n3. Get the value of SQL port for `indexserver`.\n\n### HANA 2.0\n\nThe following instructions describe how to get the instance and SQL port\nnumbers from HANA 2.0:\n\n1. Go to **System**.\n\n2. Click the **Landscape** tab.\n\n3. Click the **Services** tab.\n\n4. Under the **Service** column, navigate to the `nameserver`.\n\n5. Get the value of SQL port. The instance number are the second and\n third digits of the SQL port number.\n\n### Step 3: Create the SAP HANA hdbuserstore key for system database backup users\n\nBackup and DR Service recommends this naming convention for the userstore key name:\nFor SYSTEMDB, set the key name to `Database backup username`.\nFor example: Database backup username (`Actbackup`)\nSet SYSTEMDB---key_name--- (`ACTBACKUP`)\n\n**Procedure for single node HANA system**\n\n1. Connect to the HANA database system using SSH and login to (sid)adm: `su - (sid)adm`\n\n2. Change directory: `cd exe`\n\n3. Create entries in hdbuserstore using command `hdbuserstore`:\n\n ./hdbuserstore SET (key_name) (SAP HANA database hostname):(port) (DB_user_name) (DB_user_password)\n\n In this example: \n\n ./hdbuserstore SET ACTBACKUP s4hana:30013 ACTBACKUP (DB_user_password)\n\n4. Check the keystore: `./hdbuserstore list`\n\n| **Note:** If the hostname is not included, you will get the error: `ERRORMSG: USERSTORE KEY - Does not have valid hostname configured!`\n\nSet up the log mode and log backup in HANA Studio\n-------------------------------------------------\n\nUse the HANA Studio set the HANA log mode and log backup location for\nBackup and DR to take backups of HANA DB transaction logs:\n\n1. In SAP HANA HDB studio, make sure log backup is set correctly under\n **DATABASE (SYSTEMDB FOR HANA 2.0)** \\\u003e **Backup** \\\u003e\n **Configuration** page:\n\n - Destination type is **File**.\n\n - Destination is set to a local file system mount path.\n\n - Backup interval is set to **required RPO**.\n\n - Automatic log backup is enabled.\n\n - Database log_mode must be set to **normal**.\n\n2. Check under Database configuration: DATABASE (SYSTEMDB FOR HANA 2.0) \\\u003e\n Configuration page. In the filter, type **basepath**.\n\n3. Verify that `basepath_logbackup` is set correctly:\n\n - Set the `basepath_catalogbackup` to the same as `basepath_logbackup`.\n\n - Open the `basepath_catalogbackup` edit page.\n\n - Set the **New value** to the same as `basepath_logbackup` and click **Save**.\n This ensures the backup of the catalog with log backup for point in\n time recovery.\n\n4. Run the re-config for the values to take effect.\n\nInstall the Backup and DR agent (connector) on SAP HANA Servers\n---------------------------------------------------------------\n\nThe Backup and DR agent, a small-footprint, lightweight service on the SAP HANA\nserver, is used to capture an application-consistent copy of SAP HANA\ndatabases. It uses changed block tracking to identify changes to database data\nfor Backup and DR's incremental forever capture strategy. All SAP HANA servers\nthat have data to be protected by Backup and DR must have the Backup and DR agent\ninstalled.\n\n1. Download the agent installer file as detailed in [Obtain the right Backup and DR agent for your host](/backup-disaster-recovery/docs/concepts/about-connector#right-connector)\n\n2. Log on to the Linux server as root.\n\n3. Install the agent as detailed in [Install the Backup and DR agent on a Linux host](/backup-disaster-recovery/docs/configuration/linux-agent)\n\nWhat's next\n-----------\n\n[Add an SAP HANA database host, and discover and protect its databases](/backup-disaster-recovery/docs/configuration/discover-sap-hana)\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)"]]
