    • This is achieved in a computer system employing a multiple facility operating system architecture. The computer system includes a plurality of processor units for implementing a predetermined set of peer-level facilities wherein each peer-level facility includes a plurality of related functions and a communications bus for interconnecting the processor units. Each of the processor units includes a central processor and the stored program that, upon execution, provides for the implementation of a predetermined peer-level facility of the predetermined set of peer-level facilities, and for performing a multi-tasking interface function. The multi-tasking interface function is responsive to control messages for selecting for execution functions of the predetermined peer-level facility and that is responsive to the predetermined peer-level facility for providing control messages to request or to respond to the performance of functions of another peer-level facility of the computer system. The multi-tasking interface functions of each of the plurality of processor units communicate among one another via the network bus.
    • 这在使用多设备操作系统架构的计算机系统中实现。 计算机系统包括用于实现预定的一组对等级设施的多个处理器单元,其中每个对等级设施包括多个相关功能,以及用于互连处理器单元的通信总线。 每个处理器单元包括中央处理器和存储的程序,其在执行时提供预定对等级设备集合的预定对等级设施的实现,并且用于执行多任务接口功能。 多任务接口功能响应于控制消息,用于选择预定对等级设施的执行功能,并且响应于预定的对等级设施提供控制消息以请求或响应其他功能的执行 计算机系统的同级设施。 多个处理器单元中的每一个的多任务接口功能经由网络总线相互通信。

    • The invention provides a method and system for duplicating all or part of a file system while maintaining consistent copies of the file system. The file server maintains a set of snapshots, each indicating a set of storage blocks making up a consistent copy of the file system as it was at a known time. Each snapshot can be used for a purpose other than maintaining the coherency of the file system, such as duplicating or transferring a backup copy of the file system to a destination storage medium. In a preferred embodiment, the snapshots can be manipulated to identify sets of storage blocks in the file system for incremental backup or copying, or to provide a file system backup that is both complete and relatively inexpensive. Also in a preferred embodiment, shadow snapshots can be maintained, with a shadow snapshot including a set of member storage blocks that formed a consistent file system other than an active file system, with a set of selected member storage blocks removed from the consistent file system.
    • 本发明提供了一种用于在保持文件系统的一致副本的同时复制文件系统的全部或部分的方法和系统。 文件服务器维护一组快照,每个快照指示一组存储块,构成文件系统的一致副本,就像在已知时间一样。 每个快照可以用于维护文件系统的一致性之外的目的,例如将文件系统的备份副本复制或传送到目的地存储介质。 在优选实施例中,可以操纵快照以识别用于增量备份或复制的文件系统中的存储块集合,或提供完整且相对便宜的文件系统备份。 同样在优选实施例中,可以维护影子快照,其中,影子快照包括一组成员存储块,其形成除活动文件系统之外的一致的文件系统,并且从一致的文件系统中移除了一组选定的成员存储块 。
