VSS 请求程序和 SharePointVSS requestors and SharePoint

摘要: 了解卷影复制服务 (VSS) 系统的请求程序系统如何使用 Microsoft SharePoint。 Windows Server 中的 VSS 可用于创建可备份和还原 Microsoft SharePoint Foundation 的应用程序。VSS 提供了一个基础结构,使第三方存储管理程序、业务程序,以及硬件提供程序进行合作,以创建和管理卷影副本。基于此基础结构的解决方案可以使用卷影副本(或镜像副本)来备份和还原一个或多个 SharePoint Foundation 数据库。Summary: Learn about how the requestor system of the Volume Shadow Copy Service (VSS) system works with Microsoft SharePoint. VSS in Windows Server can be used to create applications that back up and restore Microsoft SharePoint Foundation. The VSS provides an infrastructure that enables third-party storage management programs, business programs, and hardware providers to cooperate in creating and managing shadow copies. Solutions based on this infrastructure can use the shadow copies (or mirrored copies) to back up and restore one or more SharePoint Foundation databases.

VSS 请求程序系统VSS requestor system

VSS 在请求程序(备份应用程序)、编写器(如 SharePoint Foundation 和 Microsoft SQL Server 之类的 Windows 应用程序)以及提供程序(系统、软件或用于创建卷影副本的硬件组件)之间进行协调。若要使用 VSS 功能来备份 SharePoint Foundation,备份程序必须包括了解 SharePoint Foundation 的 VSS 请求程序。由于 Windows Server 提供的备份程序不具备这些请求程序,组织必须使用第三方备份应用程序。The VSS coordinates communication among requestors (backup applications), Writers (Windows applications such as SharePoint Foundation and Microsoft SQL Server), and Providers (system, software, or hardware components that create the shadow copies). To use the VSS feature to back up SharePoint Foundation, the backup program must include a VSS requestor that is aware of SharePoint Foundation. Because the backup program that is provided with Windows Server has no such requestor, organizations must use third-party backup applications.

为了符合 SharePoint Foundation 的要求,基于 VSS 的备份应用程序必须遵循两个基本要求,以确保卷影副本备份的完整性和可恢复性。客户应与其备份供应商一同验证备份应用程序是否满足本主题中列出的 SharePoint Foundation 的合规性要求。To be compliant with SharePoint Foundation, backup applications that are based on VSS must follow two basic requirements to ensure the integrity and recoverability of shadow copy backups. Customers should verify with their backup vendors that the backup application fulfills the compliance requirements for SharePoint Foundation listed in this topic.

以下是卷影副本备份应用程序必须遵循的 SharePoint Foundation 要求,以确保 SharePoint Foundation 数据库的完整性和可恢复性。Following are the SharePoint Foundation requirements that a shadow copy backup application must follow to ensure the integrity and recoverability of SharePoint Foundation databases:

  • SharePoint Foundation 数据库和搜索索引文件必须专门通过 SPF-VSS 编写器进行备份。SharePoint Foundation databases and search index files must be backed up exclusively through the SPF-VSS Writer.

  • 备份应用程序必须验证卷影副本备份集的完整性。还原到原始位置的操作必须专门由 SPF-VSS 编写器执行。The backup application must validate the integrity of the shadow copy backup set. Restore operations to original location must be done exclusively with the SPF-VSS Writer.

还原Restoring

在执行还原操作之前,必须满足以下条件:Before executing a restoration, the following conditions must be met:

  • 以下服务必须 启动The following services must be started :

    • SharePoint VSS 编写器SharePoint VSS Writer

    • 卷影副本Volume Shadow Copy

    • SharePoint 跟踪SharePoint Tracing

  • 以下服务必须 停止The following services must be stopped :

    • SharePoint 管理SharePoint Administration

    • SharePoint 搜索SharePoint Search

    • SharePoint 计时器SharePoint Timer

    • SharePoint Server 搜索(如果已安装 SharePoint Server。)SharePoint Server Search (If SharePoint Server is installed.)

  • 如果还原的是整个服务器场,则 SharePoint Foundation 和 Internet 信息服务器 (IIS) 必须关闭。If the whole farm is being restored, SharePoint Foundation and Internet Information Server (IIS) must be shutdown.

  • 如果仅还原选定 Web 应用程序或其他组件,则 Web 应用程序必须关闭,并且在还原过程中不能使用这些组件。If only selected Web applications or other components are being restored, the Web applications must be shutdown and the components may not be in use during the restoration.
