教程:备份 Azure VM 中的 SAP HANA 数据库Tutorial: Back up SAP HANA databases in an Azure VM

本教程介绍如何将 Azure VM 上运行的 SAP HANA 数据库备份到 Azure 备份恢复服务保管库。This tutorial shows you how to back up SAP HANA databases running on Azure VMs to an Azure Backup Recovery Services vault. 在本文中,你将学习如何:In this article you'll learn how to:

  • 创建并配置保管库Create and configure a vault
  • 发现数据库Discover databases
  • 配置备份Configure backups

这里有我们目前支持的所有方案。Here are all the scenarios that we currently support.

备注

自 2020 年 8 月 1 日起,适用于 RHEL 的 SAP HANA 备份(7.4、7.6、7.7 和 8.1)已正式发布。As of August 1st, 2020, SAP HANA backup for RHEL (7.4, 7.6, 7.7 & 8.1) is generally available.

先决条件Prerequisites

在配置备份之前,请确保执行以下操作:Make sure you do the following before configuring backups:

  • 在运行 SAP HANA 的 VM 所在的同一区域和订阅中标识或创建一个恢复服务保管库Identify or create a Recovery Services vault in the same region and subscription as the VM running SAP HANA.
  • 允许从 VM 连接到 Internet,以便 VM 可以访问 Azure,如下面的设置网络连接过程中所述。Allow connectivity from the VM to the internet, so that it can reach Azure, as described in the set up network connectivity procedure below.
  • 对于 Azure 资源管理器,请确保 SAP HANA 服务器 VM 名称和资源组名称的组合长度不超过 84 个字符(对于经典 VM,则不超过 77 个字符)。Ensure that the combined length of the SAP HANA Server VM name and the Resource Group name doesn't exceed 84 characters for Azure Resource Manager (ARM_ VMs (and 77 characters for classic VMs). 此限制是因为某些字符由该服务预留。This limitation is because some characters are reserved by the service.
  • hdbuserstore 中应存在一个满足以下条件的密钥:A key should exist in the hdbuserstore that fulfills the following criteria:
    • 它应该出现在默认的 hdbuserstore 中。It should be present in the default hdbuserstore. 默认值为安装 SAP HANA 的 <sid>adm 帐户。The default is the <sid>adm account under which SAP HANA is installed.
    • 对于 MDC,该密钥应指向 NAMESERVER 的 SQL 端口。For MDC, the key should point to the SQL port of NAMESERVER. 对于 SDC,它应指向 INDEXSERVER 的 SQL 端口In the case of SDC, it should point to the SQL port of INDEXSERVER
    • 它应该包含用于添加和删除用户的凭据It should have credentials to add and delete users
    • 请注意,成功运行预注册脚本后可以删除此密钥Note that this key can be deleted after running the pre-registration script successfully
  • 在安装了 HANA 的虚拟机中,以 root 用户身份运行 SAP HANA 备份配置脚本(注册前脚本)。Run the SAP HANA backup configuration script (pre-registration script) in the virtual machine where HANA is installed, as the root user. 此脚本可使 HANA 系统做好备份的准备。This script gets the HANA system ready for backup. 请参阅注册前脚本的功能部分来详细了解注册前脚本。Refer to the What the pre-registration script does section to understand more about the pre-registration script.
  • 如果 HANA 安装程序使用专用终结点,请使用 -sn 或 -skip-network-checks 参数运行预注册脚本If your HANA setup uses Private Endpoints, run the pre-registration script with the -sn or --skip-network-checks parameter.

备注

预注册脚本将为 RHEL(7.4、7.6 和 7.7)上运行的 SAP HANA 工作负载安装 compat-unixODBC234,为 RHEL 8.1 上的安装 unixODBC 。The preregistration script installs the compat-unixODBC234 for SAP HANA workloads running on RHEL (7.4, 7.6 and 7.7) and unixODBC for RHEL 8.1. 此包位于 SAP 解决方案 (RPM) 存储库中的 RHEL for SAP HANA(适用于 RHEL 7 服务器)更新服务中This package is located in the RHEL for SAP HANA (for RHEL 7 Server) Update Services for SAP Solutions (RPMs) repo. 对于 Azure 市场 RHEL 映像,存储库应为 rhui-rhel-sap-hana-for-rhel-7-server-rhui-e4s-rpms。For an Azure Marketplace RHEL image the repo would be rhui-rhel-sap-hana-for-rhel-7-server-rhui-e4s-rpms.

设置网络连接Set up network connectivity

对于所有操作,在 Azure VM 上运行的 SAP HANA 数据库需要连接到 Azure 备份服务、Azure 存储和 Azure Active Directory。For all operations, an SAP HANA database running on an Azure VM requires connectivity to the Azure Backup service, Azure Storage, and Azure Active Directory. 这可以通过使用专用终结点,或允许访问所需的公共 IP 地址或 FQDN 来实现。This can be achieved by using private endpoints or by allowing access to the required public IP addresses or FQDNs. 如果不允许正确连接到所需的 Azure 服务,则可能会导致诸如数据库发现、配置备份、执行备份和还原数据等操作失败。Not allowing proper connectivity to the required Azure services may lead to failure in operations like database discovery, configuring backup, performing backups, and restoring data.

下表列出了可用于建立连接的各种备选方案:The following table lists the various alternatives you can use for establishing connectivity:

选项Option 优点Advantages 缺点Disadvantages
专用终结点Private endpoints 允许通过虚拟网络中的专用 IP 进行备份Allow backups over private IPs inside the virtual network

提供网络和保管库端的精细控制Provide granular control on the network and vault side
产生标准专用终结点开销Incurs standard private endpoint costs
NSG 服务标记NSG service tags 由于范围更改会自动合并,因此管理变得更容易Easier to manage as range changes are automatically merged

无额外成本No additional costs
只可用于 NSGCan be used with NSGs only

提供对整个服务的访问Provides access to the entire service
Azure 防火墙 FQDN 标记Azure Firewall FQDN tags 自动管理必需的 FQDN,因此更易于管理Easier to manage since the required FQDNs are automatically managed 只可用于 Azure 防火墙Can be used with Azure Firewall only
允许访问服务 FQDN/IPAllow access to service FQDNs/IPs 无额外成本No additional costs

适用于所有网络安全设备和防火墙Works with all network security appliances and firewalls
可能需要访问一组广泛的 IP 或 FQDNA broad set of IPs or FQDNs may be required to be accessed
使用 HTTP 代理Use an HTTP proxy 对 VM 进行单点 Internet 访问Single point of internet access to VMs 通过代理软件运行 VM 带来的额外成本Additional costs to run a VM with the proxy software

关于使用这些选项的更多细节如下:More details around using these options are shared below:

专用终结点Private endpoints

使用专用终结点,可以从虚拟网络内的服务器安全地连接到恢复服务保管库。Private endpoints allow you to connect securely from servers inside a virtual network to your Recovery Services vault. 专用终结点为保管库使用 VNET 地址空间中的 IP。The private endpoint uses an IP from the VNET address space for your vault. 虚拟网络中的资源与保管库之间的网络流量将通过虚拟网络和 Microsoft 主干网络上的专用链接传输。The network traffic between your resources inside the virtual network and the vault travels over your virtual network and a private link on the Microsoft backbone network. 这样就不会从公共 Internet 泄露信息。This eliminates exposure from the public internet. 此处详细了解 Azure 备份的专用终结点。Read more on private endpoints for Azure Backup here.

NSG 标记NSG tags

如果使用网络安全组 (NSG),请使用 AzureBackup 服务标记以允许对 Azure 备份进行出站访问。If you use Network Security Groups (NSG), use the AzureBackup service tag to allow outbound access to Azure Backup. 除了 Azure 备份标记外,还需要通过为 Azure AD (AzureActiveDirectory) 和 Azure 存储(存储)创建类似的 NSG 规则,以便在连接后进行身份验证和数据传输。In addition to the Azure Backup tag, you also need to allow connectivity for authentication and data transfer by creating similar NSG rules for Azure AD (AzureActiveDirectory) and Azure Storage(Storage). 以下步骤介绍了为 Azure 备份标记创建规则的过程:The following steps describe the process to create a rule for the Azure Backup tag:

  1. 在“所有服务”中转到“网络安全组”,然后选择“网络安全组”。In All Services, go to Network security groups and select the network security group.

  2. 在“设置”下选择“出站安全规则”。Select Outbound security rules under Settings.

  3. 选择 添加Select Add. 根据安全规则设置中所述,输入创建新规则所需的所有详细信息。Enter all the required details for creating a new rule as described in security rule settings. 请确保将选项“目标”设置为“服务标记”,将“目标服务标记”设置为“AzureBackup”。Ensure the option Destination is set to Service Tag and Destination service tag is set to AzureBackup.

  4. 选择“添加”,保存新创建的出站安全规则。Select Add to save the newly created outbound security rule.

同样,可以为 Azure 存储和 Azure AD 创建 NSG 出站安全规则You can similarly create NSG outbound security rules for Azure Storage and Azure AD. 有关服务标记的详细信息,请参阅此文For more information on service tags, see this article.

Azure 防火墙标记Azure Firewall tags

如果使用 Azure 防火墙,请使用 AzureBackup Azure 防火墙 FQDN 标记创建应用程序规则。If you're using Azure Firewall, create an application rule by using the AzureBackup Azure Firewall FQDN tag. 这允许对 Azure 备份进行所有出站访问。This allows all outbound access to Azure Backup.

允许访问服务 IP 范围Allow access to service IP ranges

如果选择允许访问服务 IP,请参阅此处的 JSON 文件中的 IP 范围。If you choose to allow access service IPs, refer to the IP ranges in the JSON file available here. 你需要允许访问与 Azure 备份、Azure 存储和 Azure Active Directory 对应的 IP。You'll need to allow access to IPs corresponding to Azure Backup, Azure Storage, and Azure Active Directory.

允许访问服务 FQDNAllow access to service FQDNs

还可以使用以下 FQDN 以允许从服务器访问所需的服务:You can also use the following FQDNs to allow access to the required services from your servers:

服务Service 要访问的域名Domain names to be accessed
Azure 备份Azure Backup *.backup.azure.cn
Azure 存储Azure Storage *.blob.core.chinacloudapi.cn

*.queue.core.chinacloudapi.cn
Azure ADAzure AD 根据这篇文章,允许访问第 56 和 59 节下的 FQDNAllow access to FQDNs under sections 56 and 59 according to this article

使用 HTTP 代理服务器路由流量Use an HTTP proxy server to route traffic

备份在 Azure VM 上运行的 SAP HANA 数据库时,该 VM 上的备份扩展将使用 HTTPS API 将管理命令发送到 Azure 备份,并将数据发送到 Azure 存储。When you back up an SAP HANA database running on an Azure VM, the backup extension on the VM uses the HTTPS APIs to send management commands to Azure Backup and data to Azure Storage. 备份扩展还使用 Azure AD 进行身份验证。The backup extension also uses Azure AD for authentication. 通过 HTTP 代理路由这三个服务的备份扩展流量。Route the backup extension traffic for these three services through the HTTP proxy. 使用上面提到的 IP 和 FQDN 列表,以允许访问所需的服务。Use the list of IPs and FQDNs mentioned above for allowing access to the required services. 不支持已经过身份验证的代理服务器。Authenticated proxy servers aren't supported.

注册前脚本的功能What the pre-registration script does

注册前脚本执行以下功能:Running the pre-registration script performs the following functions:

  • 脚本将基于 Linux 分发安装或更新 Azure 备份代理所需的任何包。Based on your Linux distribution, the script installs or updates any necessary packages required by the Azure Backup agent.
  • 执行与 Azure 备份服务器和相关服务(例如 Azure Active Directory 和 Azure 存储)之间的出站网络连接检查。It performs outbound network connectivity checks with Azure Backup servers and dependent services like Azure Active Directory and Azure Storage.
  • 使用先决条件中列出的用户密钥登录到 HANA 系统。It logs into your HANA system using the user key listed as part of the prerequisites. 此用户密钥用于在 HANA 系统中创建备份用户 (AZUREWLBACKUPHANAUSER),成功运行预注册脚本后,可以删除该用户密钥。The user key is used to create a backup user (AZUREWLBACKUPHANAUSER) in the HANA system and the user key can be deleted after the pre-registration script runs successfully.
  • 为 AZUREWLBACKUPHANAUSER 分配了以下必需的角色和权限:AZUREWLBACKUPHANAUSER is assigned these required roles and permissions:
    • 对于 MDC:数据库管理员和备份管理员(从 HANA 2.0 SPS05 开始):在还原期间创建新数据库。For MDC: DATABASE ADMIN and BACKUP ADMIN (from HANA 2.0 SPS05 onwards): to create new databases during restore.
    • 对于 SDC:备份管理员:在还原期间创建新数据库。For SDC: BACKUP ADMIN: to create new databases during restore.
    • 目录读取:读取备份目录。CATALOG READ: to read the backup catalog.
    • SAP_INTERNAL_HANA_SUPPORT:访问一些专用表。SAP_INTERNAL_HANA_SUPPORT: to access a few private tables. 仅对于 HANA 2.0 SPS04 Rev 46 以下的 SDC 和 MDC 版本是必需的。Only required for SDC and MDC versions below HANA 2.0 SPS04 Rev 46. 对于 HANA 2.0 SPS04 Rev 46 和更高版本不是必需的,因为我们现在会通过 HANA 团队提供的修补程序从公共表中获取所需的信息。This is not required for HANA 2.0 SPS04 Rev 46 and above since we are getting the required information from public tables now with the fix from HANA team.
  • 此脚本在 hdbuserstore 中为 HANA 备份插件的 AZUREWLBACKUPHANAUSER 添加一个密钥,以便处理所有操作(数据库查询、还原操作、配置和运行备份)。The script adds a key to hdbuserstore for AZUREWLBACKUPHANAUSER for the HANA backup plug-in to handle all operations (database queries, restore operations, configuring and running backup).

备注

你可以将先决条件中列出的用户密钥作为参数显式传递给预注册脚本:-sk SYSTEM_KEY_NAME, --system-key SYSTEM_KEY_NAMEYou can explicitly pass the user key listed as part of the prerequisites as a parameter to the pre-registration script: -sk SYSTEM_KEY_NAME, --system-key SYSTEM_KEY_NAME

若要了解脚本接受哪些其他参数,请使用命令 bash msawb-plugin-config-com-sap-hana.sh --helpTo learn what other parameters the script accepts, use the command bash msawb-plugin-config-com-sap-hana.sh --help

若要确认创建密钥,请在具有 SIDADM 凭据的 HANA 计算机上运行以下 HDBSQL 命令:To confirm the key creation, run the HDBSQL command on the HANA machine with SIDADM credentials:

hdbuserstore list

命令输出应显示 {SID}{DBNAME} 密钥,用户显示为 AZUREWLBACKUPHANAUSER。The command output should display the {SID}{DBNAME} key, with the user shown as AZUREWLBACKUPHANAUSER.

备注

请确保 /usr/sap/{SID}/home/.hdb/ 下有一组唯一的 SSFS 文件。Make sure you have a unique set of SSFS files under /usr/sap/{SID}/home/.hdb/. 此路径中应只有一个文件夹。There should be only one folder in this path.

创建恢复服务保管库Create a Recovery Services vault

恢复服务保管库是用于存储在不同时间创建的备份和恢复点的实体。A Recovery Services vault is an entity that stores the backups and recovery points created over time. 恢复服务保管库还包含与受保护虚拟机关联的备份策略。The Recovery Services vault also contains the backup policies that are associated with the protected virtual machines.

若要创建恢复服务保管库,请执行以下操作:To create a Recovery Services vault:

  1. Azure 门户中登录到自己的订阅。Sign in to your subscription in the Azure portal.

  5. 在 VM 上运行此脚本后,在“选择虚拟机”中选择该 VM。After running the script on the VM, in Select Virtual Machines, select the VM. 然后选择“发现 DB”。Then select Discover DBs.

  6. Azure 备份可发现该 VM 上的所有 SAP HANA 数据库。Azure Backup discovers all SAP HANA databases on the VM. 在发现期间,Azure Backup 将 VM 注册到保管库,并在该 VM 上安装扩展。During discovery, Azure Backup registers the VM with the vault, and installs an extension on the VM. 不会在数据库中安装任何代理。No agent is installed on the database.

    发现数据库

配置备份Configure backup

发现我们要备份的数据库之后,现在可以启用备份。Now that the databases we want to back up are discovered, let's enable backup.

  1. 选择“配置备份”。Select Configure Backup.

    配置备份

  2. 在“选择要备份的项”中,选择一个或多个要保护的数据库,然后选择“确定” 。In Select items to back up, select one or more databases that you want to protect, and then select OK.

    选择要备份的项

  3. 在“备份策略”>“选择备份策略”中,按照下一部分中的说明,为数据库创建一个新的备份策略。In Backup Policy > Choose backup policy, create a new backup policy for the database(s), in accordance with the instructions in the next section.

    选择备份策略

  4. 创建策略后,在“备份菜单”中选择“启用备份” 。After creating the policy, on the Backup menu, select Enable backup.

    选择“启用备份”

  5. 在门户的“通知”区域跟踪备份配置进度。Track the backup configuration progress in the Notifications area of the portal.

创建备份策略Creating a backup policy

备份策略定义备份创建时间以及这些备份的保留时间。A backup policy defines when backups are taken, and how long they're retained.

  • 策略是在保管库级别创建的。A policy is created at the vault level.
  • 多个保管库可以使用相同的备份策略,但必须向每个保管库应用该备份策略。Multiple vaults can use the same backup policy, but you must apply the backup policy to each vault.

按以下方式指定策略设置:Specify the policy settings as follows:

  1. 在“策略名称”处输入新策略的名称。In Policy name, enter a name for the new policy. 对于本例,请输入“SAPHANA”。In this case, enter SAPHANA.

    输入新策略的名称

  2. 在“完整备份策略”中选择一个 备份频率In Full Backup policy, select a Backup Frequency. 可以选择“每日”或“每周” 。You can choose Daily or Weekly. 对于本教程,我们选择了“每日”备份。For this tutorial, we chose the Daily backup.

    选择备份频率

  3. 在“保持期”中,对完整备份配置保留设置。In Retention Range, configure retention settings for the full backup.

    • 默认情况下,选择所有选项。By default, all options are selected. 清除你不想使用的所有保持期限制,并设置要使用的选项。Clear any retention range limits you don't want to use and set those that you do.
    • 任何备份类型(完整/差异/日志)的最短保持期均为七天。The minimum retention period for any type of backup (full/differential/log) is seven days.
    • 恢复点已根据其保留范围标记为保留。Recovery points are tagged for retention based on their retention range. 例如,如果选择每日完整备份,则每天只触发一次完整备份。For example, if you select a daily full backup, only one full backup is triggered each day.
    • 根据每周保持期和设置,将会标记并保留特定日期的备份。The backup for a specific day is tagged and retained based on the weekly retention range and setting.
    • 每月和每年保留范围的行为类似。The monthly and yearly retention ranges behave in a similar way.
  4. 在“完整备份策略”菜单中,选择“确定”接受设置。 In the Full Backup policy menu, select OK to accept the settings.

  5. 然后选择“差异备份”,以添加差异策略。Then select Differential Backup to add a differential policy.

  6. 在“差异备份策略”中,选择“启用”打开频率和保留控件。In Differential Backup policy, select Enable to open the frequency and retention controls. 我们在每个星期日的凌晨 2:00 启用了差异备份,保持期为 30 天 。We've enabled a differential backup every Sunday at 2:00 AM, which is retained for 30 days.

    差异备份策略

    备注

    增量备份现在提供公共预览版。Incremental backups are now available in public preview. 可以选择差异备份或增量备份作为每日备份,但不能同时选择两者。You can choose either a differential or an incremental as a daily backup but not both.

    • 每天最多可以触发一次增量备份。At most, you can trigger one incremental backup per day.
    • 增量备份最多可以保留 180 天。Incremental backups can be retained for a maximum of 180 days. 如果需要保留更长时间,必须使用完整备份。If you need longer retention, you must use full backups.

    增量备份策略

  8. 选择“确定”保存策略,并返回“备份策略”主菜单。 Select OK to save the policy and return to the main Backup policy menu.

  9. 请选择“日志备份”,以添加事务日志备份策略。Select Log Backup to add a transactional log backup policy,

    • “日志备份”默认设为“启用” 。Log Backup is by default set to Enable. 由于 SAP HANA 管理所有日志备份,此类备份无法被禁用。This can't be disabled as SAP HANA manages all log backups.
    • 我们已将备份计划设置为 2 小时,保持期为 15 天 。We've set 2 hours as the Backup schedule and 15 days of retention period.

    日志备份策略

    备注

    日志备份仅在成功完成一次完整备份之后进行。Log backups only begin to flow after one successful full backup is completed.

  10. 选择“确定”保存策略,并返回“备份策略”主菜单。 Select OK to save the policy and return to the main Backup policy menu.

  11. 完成定义备份策略后,选择“确定”。After you finish defining the backup policy, select OK.
