可以通过 Azure Site Recovery 保护哪些工作负荷?What workloads can you protect with Azure Site Recovery?

本文介绍了可以使用 Azure Site Recovery 服务为灾难恢复保护的工作负荷和应用程序。This article describes workloads and applications you can protect for disaster recovery with the Azure Site Recovery service.

概述Overview

组织需要制定业务连续性和灾难恢复 (BCDR) 策略来确保工作负荷和数据在计划和非计划停机期间保持安全和可用,并尽快恢复正常运行。Organizations need a business continuity and disaster recovery (BCDR) strategy to keep workloads and data safe and available during planned and unplanned downtime, and recover to regular working conditions as soon as possible.

Site Recovery 就是能够帮助实现 BCDR 策略的一个 Azure 服务。Site Recovery is an Azure service that contributes to your BCDR strategy. 使用 Site Recovery,可将应用程序感知的复制部署到云或辅助站点中。Using Site Recovery, you can deploy application-aware replication to the cloud, or to a secondary site. 无论应用是基于 Windows 还是 Linux,是在物理服务器、VMware 还是 Hyper-V 上运行,都可以使用 Site Recovery 协调复制、执行灾难恢复测试,以及运行故障转移和故障回复。Whether your apps are Windows or Linux-based, running on physical servers, VMware or Hyper-V, you can use Site Recovery to orchestrate replication, perform disaster recovery testing, and run failovers and failback.

Site Recovery 集成 Microsoft 应用程序,其中包括 SharePoint、Exchange、Dynamics、SQL Server 和 Active Directory。Site Recovery integrates with Microsoft applications, including SharePoint, Exchange, Dynamics, SQL Server, and Active Directory.

为何使用 Site Recovery 复制应用程序?Why use Site Recovery for application replication?

Site Recovery 可帮助实现应用程序级的保护和恢复,如下所示:Site Recovery contributes to application-level protection and recovery as follows:

  • 不区分应用,为受支持计算机上运行的任何工作负荷提供复制。App-agnostic, providing replication for any workloads running on a supported machine.
  • 几乎同步的复制,RPO 低至 30 秒,满足大多数关键业务应用的需要。Near-synchronous replication, with RPOs as low as 30 seconds to meet the needs of most critical business apps.
  • 针对单层或多层应用程序的应用一致性快照。App-consistent snapshots, for single or multi-tier applications.
  • 集成 SQL Server AlwaysOn,纳入了其他应用程序级复制技术,其中包括 AD 复制、SQL AlwaysOn、Exchange 数据库可用性组 (DAG) 和 Oracle 数据防护。Integration with SQL Server AlwaysOn, and partnership with other application-level replication technologies, including AD replication, SQL AlwaysOn, Exchange Database Availability Groups (DAGs) and Oracle Data Guard.
  • 灵活的恢复计划,一次单击即可恢复整个应用程序堆栈,包括在计划中使用外部脚本和手动操作。Flexible recovery plans, that enable you to recover an entire application stack with a single click, and to include external scripts and manual actions in the plan.
  • Site Recovery 和 Azure 中的高级网络管理可以简化应用的网络要求,包括保留 IP 地址、配置负载均衡或集成 Azure 流量管理器以降低 RTO 网络切换数。Advanced network management in Site Recovery and Azure to simplify app network requirements, including the ability to reserve IP addresses, configure load-balancing, and integration with Azure Traffic Manager, for low RTO network switchovers.
  • 丰富的自动化库,提供特定于应用程序的生产就绪型脚本,可以下载并与恢复计划集成。A rich automation library that provides production-ready, application-specific scripts that can be downloaded and integrated with recovery plans.

复制 Active Directory 和 DNSReplicate Active Directory and DNS

Active Directory 和 DNS 基础结构对于大多数企业应用而言至关重要。An Active Directory and DNS infrastructure are essential to most enterprise apps. 在灾难恢复过程中恢复工作负荷和应用之前,需要保护和恢复这些基础结构组件。During disaster recovery, you'll need to protect and recover these infrastructure components, before recovering your workloads and apps.

可以使用站点恢复,为 Active Directory 和 DNS 创建一个完整的自动化灾难恢复计划。You can use Site Recovery to create a complete automated disaster recovery plan for Active Directory and DNS. 例如,要将 SharePoint 和 SAP 从主站点故障转移到辅助站点,可以先设置可故障转移 Active Directory 的恢复计划,然后设置额外的应用特定计划,以故障转移依赖于 Active Directory 的其他应用。For example, if you want to fail over SharePoint and SAP from a primary to a secondary site, you can set up a recovery plan that fails over Active Directory first, and then an additional app-specific recovery plan to fail over the other apps that rely on Active Directory.

按如下所述使用 Site Recovery 来保护 IIS 部署:Use Site Recovery to protect your IIS deployment, as follows:

Azure Site Recovery 可以将环境中的关键组件复制到冷远程站点或公有云(例如 Azure),从而提供灾难恢复。Azure Site Recovery provides disaster recovery by replicating the critical components in your environment to a cold remote site or a public cloud like Azure. 由于包含 Web 服务器和数据库的虚拟机将复制到恢复站点,因此不需单独备份配置文件或证书。Since the virtual machines with the web server and the database are being replicated to the recovery site, there is no requirement to backup configuration files or certificates separately. 依赖于环境变量(在故障转移后已更改)的应用程序映射和绑定可以通过集成到灾难恢复计划中的脚本进行更新。The application mappings and bindings dependent on environment variables that are changed post failover can be updated through scripts integrated into the disaster recovery plans. 仅当故障转移时,才会在恢复站点中启动虚拟机。Virtual machines are brought up on the recovery site only in the event of a failover. 不仅如此,Azure Site Recovery 还提供以下功能,帮助你协调端到端故障转移:Not only this, Azure Site Recovery also helps you orchestrate the end to end failover by providing you the following capabilities:

  • 顺序安排各层中虚拟机的关机和启动。Sequencing the shutdown and startup of virtual machines in the various tiers.
  • 添加脚本,以便在虚拟机启动后更新其上的应用程序依赖项和绑定。Adding scripts to allow update of application dependencies and bindings on the virtual machines after they have been started up. 也可使用脚本更新 DNS 服务器,使之指向恢复站点。The scripts can also be used to update the DNS server to point to the recovery site.
  • 通过映射主网络和恢复网络,在故障转移前向虚拟机分配 IP 地址,以便在故障转移后使用不需更新的脚本。Allocate IP addresses to virtual machines pre-failover by mapping the primary and recovery networks and hence use scripts that do not need to be updated post failover.
  • 能够对 Web 服务器上的多个 Web 应用程序进行一键式故障转移,因此在发生灾难时不会造成混淆。Ability for a one-click failover for multiple web applications on the web servers, thus eliminating the scope for confusion in the event of a disaster.
  • 能够在适用于 DR 演练的隔离环境中测试恢复计划。Ability to test the recovery plans in an isolated environment for DR drills.
