摘要： Files on a computing device are defined to include data and metadata relating to the data. Data from each file has been removed therefrom and stored at an alternate location and the file is in a reduced, ghosted form. Each of at least some ghosted files has been fully or partially reconstituted for use by retrieving the data thereof from the alternate location and associating such retrieved data with such ghosted file to form the reconstituted file. Upon receiving a trigger based on a triggering event, files are selected from among the fully and partially reconstituted files and never-ghosted files based on first predetermined selection criteria, and each of at least some of the selected files are re-ghosted.

摘要： A method and system for verifying the integrity of a storage volume. When volume verification is desired, a shadow copy of the volume is created. A verification tool operates on the shadow copy and provides a report that indicates if any errors are found in the shadow copy. If errors are found on the shadow copy, this indicates that the same errors likely still exist on the live volume. In the event of errors, a system administrator or the like may take the live volume off-line and fix the errors found.

摘要： A method and system for ordering software modules in a guaranteed order for execution. Unique values are statically assigned to software modules (e.g., filter drivers) when fully developed. Each module's assigned value determines its relative position to other modules in a stack or other arrangement, fixing the execution order for any set of filter drivers. Static values may comprise floating-point numbers, whereby each new software module may be assigned a number that enables positioning it between any two existing software modules. For example, filter drivers may be generally classified and assigned values in a range according to type. Drivers of the same type may be ordered within their general range to guarantee one possible ordering. A filter manager architecture is described, in which filter drivers register with a manager for relevant file system I/O operations. The manager calls appropriately registered filter drivers in an order based on their assigned numbers.

摘要： A model in which filter drivers are managed to receive callbacks for I/O requests in which the filter drivers have registered an interest. Per-volume instances of filter drivers register with a filter manager for pre-callbacks (for I/O to the file system) and post-callbacks (for I/O from the file system), and identify which I/O requests (e.g., create, read, write) they are registering to receive callbacks. The filter manager orders the instances for callbacks. When an I/O request is received, the filter manager converts the I/O request to callback data and calls the interested filters in the callback order, whereby the filter instances can process the I/O data. As the request returns from the file system, filters desiring post callbacks are called in the reverse order. Efficient context management for the filters and other functions, such as non-reentrant file I/O, are also provided by the model.

摘要： Briefly, the present invention provides a system and method for transparently extending the non-volatile storage on a computer system via links from one drive to one or more other drives. When the user adds a new disk drive, it is formatted but not mounted where the user can see it. The data of selected files is automatically migrated from the original drive to the new, supplemental drive, or directly created thereon, and a link is placed on the original volume to indicate to the system that the data is really elsewhere. In one implementation, this is accomplished via an NTFS reparse point on an NTFS link that is made a sparse file, thereby reclaiming the disk space on the original drive. A driver in the NTFS filter stack or the like in conjunction with the file system handles directing reads and writes to the new location, and also handles other operations including totaling the free space of each drive in response to a free space request. The driver may also enforce file operation rules, that may depend on whether the supplemental drive and/or supplemental file system is present or removed, and so forth. In this manner, the size of the original drive increases from a user's perspective, while providing a unified view of namespace, with file names present even when the supplemental drive is removed.

摘要翻译： 简而言之，本发明提供一种用于通过来自一个驱动器到一个或多个其它驱动器的链路在计算机系统上透明地扩展非易失性存储器的系统和方法。 当用户添加新的磁盘驱动器时，它被格式化，但是没有安装在用户可以看到它的位置。 所选文件的数据将自动从原始驱动器迁移到新的，补充驱动器，或直接在其上创建，并且链接放置在原始卷上，以向系统指示数据真的在其他地方。 在一个实现中，这是通过NTFS链接上的NTFS重新解析点来实现的，该NTFS链接被创建为稀疏文件，从而回收原始驱动器上的磁盘空间。 与文件系统结合的NTFS过滤堆栈等中的驱动程序处理指向新位置的读取和写入，并且还处理其他操作，包括响应于可用空间请求而合并每个驱动器的可用空间。 驱动程序还可以执行文件操作规则，这可以取决于补充驱动器和/或补充文件系统是存在还是被移除，等等。 以这种方式，原始驱动器的大小从用户的角度增加，同时提供命名空间的统一视图，即使在补充驱动器被移除时，文件名也存在。

摘要： A system and method using hardware and software components enable a storage module to maintain information about an associated storage device and its content such that the information is accessible when the storage device is offline or in a low power configuration. A general-computing host system connects to the storage module via a pluggable interface to provide information to a nonvolatile memory cache on the storage module. The storage module includes a separate power source, an output display, input buttons, and a module controller. The host system includes an application and host platform for processing file-system related events to send records to the module controller to automatically update a catalog representing storage device information in the nonvolatile memory. When offline, the user may display the catalog information and use the buttons to navigate among it. The host system may also allow the user to interactively review and modify the catalog.

摘要： A system and method using hardware and software components enable a storage module to collect and maintain control transaction data (e.g., directives/events) when a storage device of the module is offline or in a low power configuration. The storage module contains a nonvolatile memory cache and a module controller, and also may include a separate power source, an output display and input mechanism so that when offline, the user may display and navigate among catalog information corresponding to stored content to set up deferred events related to the content. When reconnected to a general-computing host system, the host system obtains the control transaction data from the storage module, and processes the data into file-system related events and other events to perform actions to the storage device and/or to other resources coupled to the host computer system. The host system may also cache transaction control data on the storage module's cache.

摘要： A service specified by an application programming interface (API) acts as a coordinator/manager of different volume snapshot providers and an administrator of snapshot providers. The API acts to standardize protocols used in connection with different snapshot providers. An Interface Volume Snapshot Service Coordinator (VSSC) with appropriate API calls is provided, which is used to coordinate and administer multiple snapshot providers as well as maintain other snapshot information. The VSSC achieves this coordination and administration whether or not the snapshot providers are hardware-based, software-based or based in a combination of different underlying technologies. The VSSC thus performs coordination and administration operations, in addition to other operations relating to snapshot providers.

摘要： A snapshot system capable of capturing snapshots of multiple volumes wherein the snapshots are coordinated. A snapshot manager determines which volumes are to be involved in a snapshot operation, and issues a message to the file system for each volume involved, each message including information sufficient to identify the volumes involved in the snapshot operation. Each file system passes its respective message down to a coordinator mechanism. The coordinator mechanism coordinates the state of each of the volumes, such as by holding writes thereto, to put each volume into a quiescent state, and then enables the snapshot to be captured. When the snapshots are captured, a snapshot set will include snapshots that are coordinated across the multiple volumes. The coordinator mechanism releases any writes being held for the volumes involved.
