    • 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.
    • 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 。

    • 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.
    • 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。

    • 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.
    • 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。
