摘要： A backup administrator can backup files from a production server on any of a plurality of different bases. In particular, some files can be replicated on a changed-byte basis. In other cases, files can be backed up by replicating updated copies of the entire file, or even byte blocks of the file. Determinations as to how a replication agent will back up a certain file or set of files can be made by a backup administrator, automatically through a predefined logic, or dynamically based on defined criteria. Corresponding agents at the production server can then flag these files as indicated. Thus, at a later point, when the DPM server requests the updates of each file, the production server can either send over copies of the changed file bytes, entire copies of the changed file itself, or even changed blocks of a file, as appropriate.
摘要翻译：备份管理员可以在多个不同的基础上的任何一个上从生产服务器备份文件。特别地，一些文件可以在更改字节的基础上进行复制。在其他情况下，可以通过复制整个文件的更新副本，甚至文件的字节块来备份文件。关于复制代理如何备份某个文件或一组文件的确定可以由备份管理员自动通过预定义的逻辑，或动态地基于定义的标准来进行。生产服务器上的相应代理可以按照指示标记这些文件。因此，在稍后的时刻，当DPM服务器请求每个文件的更新时，生产服务器可以根据需要发送改变的文件字节的副本，改变的文件本身的整个副本，甚至文件的更改的块。

摘要： A file server and a data protection manager server can work in tandem to efficiently backup protected volumes, and also provide efficient access to replicas of the protected volumes. In one implementation, a file server institutes a mock replication process, in which the file server observes data associated with write operations in one or more protected volumes. Appropriate volume allocation information can then be determined, which can be used to allocate log file, spill log file, replica volume, and shadow copy volume sizes, both at the file server and at the data protection manager server. In one implementation, the file server or data protection manager server automatically determines volume allocation information and automatically provides this information to the data protection manager server. The data protection manager server can then compare the volume allocation information with identified characteristics of its storage mediums, and implements an appropriate, efficient backup policy.
摘要翻译：文件服务器和数据保护管理器服务器可以一起工作，以有效地备份受保护的卷，并且还可以有效地访问受保护卷的副本。在一个实现中，文件服务器建立模拟复制过程，其中文件服务器观察与一个或多个受保护卷中的写入操作相关联的数据。然后可以确定适当的卷分配信息，这些信息可以用于在文件服务器和数据保护管理器服务器上分配日志文件，溢出日志文件，副本卷和卷影副本卷大小。在一个实现中，文件服务器或数据保护管理器服务器自动确定卷分配信息，并自动将该信息提供给数据保护管理器服务器。然后，数据保护管理器服务器可以将卷分配信息与其存储介质的识别特征进行比较，并且实现适当的，有效的备份策略。

摘要： Data in backup systems can be effectively protected against viruses, even if definitions for certain viruses are found after infected data have been backed up to a backup server. In one implementation, a combined filter that includes antivirus and replica filtering components can identify and process I/O system calls (e.g., including writes to files). If a virus is present, the antivirus component of the combined filter can mark the file and/or file write (and cleanse the file/file write), and pass that information to the replica component. If the file write is associated with a file to be backed up, the replica component can then pass along the antivirus filter's indications with a copy of the file write. The backup server can also identify that previous versions of the file stored at the backup server may have been infected, and can thus perform any appropriate actions.
摘要翻译：即使在将感染数据备份到备份服务器后发现某些病毒的定义，备份系统中的数据也可以有效地防范病毒。在一个实现中，包括防病毒和副本过滤组件的组合过滤器可以识别和处理I / O系统调用（例如，包括对文件的写入）。如果存在病毒，组合过滤器的防病毒组件可以标记文件和/或文件写入（并清除文件/文件写入），并将该信息传递给副本组件。如果文件写入与要备份的文件相关联，则副本组件可以随着防病毒过滤器的指示传递文件写入的副本。备份服务器还可以识别存储在备份服务器上的文件的以前版本可能已被感染，因此可以执行任何适当的操作。

摘要： Data can be protected at a production server in a virtually continuous fashion, without necessarily imposing severe constraints on the source application(s). For example, a production server can create an application-consistent backup of one or more volumes, the backups corresponding to a first instance in time. A volume filter driver can monitor data changes in each volume using an in-memory bitmap, while a log file and/or update sequence number journal can keep track of which files have been added to or updated. The volume updates are also consistent for an instance (later) in time. At the next replication cycle, such as every few minutes (however configured), the volume filter driver passes each in-memory bitmap to the physical disk on the production server. The production server then sends the updates to the backup server, which thus stores application-consistent backups for the volume for multiple instances of time.
摘要翻译：可以在生产服务器上以几乎连续的方式保护数据，而不必对源应用程序施加严格的约束。例如，生产服务器可以创建一个或多个卷的应用程序一致性备份，备份与时间对应的第一个实例。卷过滤器驱动程序可以使用内存中的位图监视每个卷中的数据更改，而日志文件和/或更新序列号日志可以跟踪哪些文件已添加到或已更新。对于一个实例（稍后）的时间，卷更新也是一致的。在下一个复制周期（例如每隔几分钟配置一次），卷过滤器驱动程序将每个内存中的位图传递到生产服务器上的物理磁盘。然后，生产服务器将更新发送到备份服务器，从而存储多个时间实例的卷的应用程序一致性备份。

摘要： A method and system for backing up and restoring data of production servers. A mapping that maps volumes of production servers to volumes of a data protection server is maintained on the data protection server. When volumes of the data protection server are backed up, the mapping may be stored on the archive media together with the data of the volumes. Later, during a restore, the mapping is read from the archive media. The mapping allows the data to be restored to the data protection server or directly to the production servers.

摘要： Migration mechanisms are disclosed herein that smartly transfer data among virtual machines, minimizing the down time of migration of such machines but maximizing the consistent state of data stored thereon. Specifically, data can be classified into three types: low volatility data (such as hard disk data), high volatility data (such a random access memory data), and immutable data (such as read only data). This data can be migrated from a source virtual machine to a target virtual machine by sending the immutable data along with the low volatility data first—before the source virtual machine has stopped itself for the migration process. Then, after the source virtual machine has stopped, high volatility data and (again) low volatility data can be sent from the source to the target. In this latter case, only differences between the low volatility data may be sent (or alternatively, new low volatility data may be sent).
摘要翻译：本文公开了移动机制，其在虚拟机之间智能地传送数据，使得这些机器的迁移停机时间最小化，但是最大化其上存储的数据的一致状态。具体来说，数据可以分为低挥发性数据（例如硬盘数据），高挥发性数据（诸如随机存取存储器数据）和不可变数据（诸如只读数据）三种类型。通过在源虚拟机已停止自身以进行迁移过程之前首先发送不可变数据以及低挥发性数据，可以将该数据从源虚拟机迁移到目标虚拟机。然后，在源虚拟机停止之后，可以从源向目标发送高波动性数据和（再次）低波动数据。在后一种情况下，仅可以发送低波动性数据之间的差异（或者可以发送新的低挥发性数据）。

摘要： Methods and systems for updating a virtual machine image. The virtual machine image may be stored as a collection of one or more virtual hard disk files. The virtual machine image is rendered to file-system data. Rendering the virtual machine image to file-system data may comprise mounting the virtual machine image's virtual hard disk drives. An analysis engine is invoked to scan the exposed file-system data to determine the update status of software constructs of the virtual machine image and data indicative of the scanning may be stored.
