Abstract: PROBLEM TO BE SOLVED: To provide a method and system for maintaining namespace consistency with a file system between selected objects maintained by a file system and a filter associated therewith. SOLUTION: The filter monitors selected types of requests (or operations associated therewith) and determines whether the object is within a namespace associated with the filter. The namespace associated with the filter is updated on the basis of a change to the object. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: Described are embodiments for allowing clients that access a distributed file system to locally cache directory metadata. The client may request a read lease which allows the client to cache the directory metadata locally and service requests received from the same application which originally requested the directory metadata using the cache. In addition, the client may also request a handle lease which allows a client to delay the closing of a directory handle and allow the handle to be reused to service subsequent directory metadata requests from the same or a different application. A client may also request a write lease which allows an application on the client to modify the directory metadata, such as by creating or deleting new files in the directory, or changing their attributes, and cache those changes.

Abstract translation: 描述了用于允许访问分布式文件系统的客户端本地地高速缓存目录元数据的实施例。 客户端可以请求读取租约，该租约允许客户端在本地缓存目录元数据，并且从最初使用缓存请求目录元数据的相同应用接收到服务请求。 另外，客户端也可以请求一个句柄租约，它允许一个客户端延迟关闭一个目录句柄，并允许该句柄被重用以服务来自相同或不同应用的后续目录元数据请求。 客户端还可以请求写租约，允许客户端上的应用程序修改目录元数据，例如通过创建或删除目录中的新文件，或更改其属性，并缓存这些更改。

Abstract: A computing device has a storage volume, a file system managing the storage volume, and a file stored on the storage volume and accessed by such file system. The file system receives an open command for the file from an application, notes that the file has been ghosted in that data of the file has been moved to an alternate location, and returns an error. The returned error is intercepted and the file system is commanded to retrieve ghosting information from the ghosted file. A handle corresponding to the ghosted file is delivered to the application, and a read command for the file is received from the application, including the handle, an offset, and a read length. Reconstituting of the ghosted file is initiated based on the data thereof at the alternate location, and after reconstituting the read command is responded to with the data requested.

Abstract: Aspects of the subject matter described herein relate to backups and change journals. In aspects, a change journal is read to determine changes that have occurred to objects of a file system. From these changes a data structure is created to capture path information and collect changes for each object. Where the data structure is insufficient to identify a complete path, the live file system is consulted. After the data structure is complete, a data protection engine uses the data structure to update a catalog at least to provide the capability to view the namespace of the protected objects at one or more times covered by the catalog.

Abstract translation: 这里描述的主题的各方面涉及备份和更改日志。 在各方面，读取更改日志以确定文件系统对象发生的更改。 从这些更改中创建数据结构以捕获路径信息并收集每个对象的更改。 在数据结构不足以识别完整路径的情况下，查阅实时文件系统。 数据结构完成后，数据保护引擎使用数据结构更新目录，至少提供在目录覆盖的一次或多次时间查看受保护对象的名称空间的功能。

Abstract: To reconstitute a ghosted file for use, a single ghosting filter on a computing device locates ghosting information in the metadata of the ghosted file and locates within the ghosting information an identification of a particular ghosting manager of the computing device, where the identified ghosting manager is responsible for the ghosted file. Thereafter, the ghosting filter communicates to the identified ghosting manager a request to obtain data of the ghosted file from a corresponding alternate location, and the identified ghosting manager does in fact obtain such requested data from such alternate location. Upon receiving the requested data of the ghosted file from the identified ghosting manager, then, the ghosting filter reconstitutes the received data to the ghosted file. The single ghosting filter is generic to all of the ghosting managers of the computing device.

Abstract: A computing device has a file stored on a storage volume by a file system and accessed through such file system. The file is defined to include data and metadata relating to the data, and at least a portion of the data of the file is removed from the file and stored at an alternate location such that the data does not occupy substantially any space on the volume and the file is in a reduced, ghosted form. The ghosted file is reconstituted for use by retrieving the data from the alternate location and associating such retrieved data with such ghosted file to form the reconstituted file.

Abstract: Se proporcionan un metodo y sistema para mantener consistencia de espacio de nombre entre objetos seleccionados mantenidos por un sistema de archivo y un filtro asociado con el. Un filtro verifica tipos seleccionados de solicitudes (u operaciones asociadas con el) y determina si el objeto esta dentro de un espacio de nombre asociado con el filtro. El espacio de nombre asociado con el filtro es actualizado basandose en un cambio al objeto.

Abstract: Se describen modalidades para que los clientes puedan tener acceso a un sistema de archivo distribuido para guardar localmente en memoria caché metadatos de directorio. El cliente puede solicitar un arrendamiento financiero de lectura que le permite al cliente guardar en memoria caché los metadatos de directorio localmente y solicitudes de servicio recibidas de la misma aplicación que originalmente solicitó los metadatos de directorio utilizando la memoria caché. Además, el cliente también puede solicitar un arrendamiento financiero de manejo que le permite a un cliente retrasar el cierre de un manejo de directorio y permite que el manejo sea reutilizado para dar servicio a las solicitudes de metadatos de directorio subsecuentes desde la misma aplicación o de una diferente. Un cliente también puede solicitar un arrendamiento financiero escrito que una aplicación en el cliente modifique los metadatos de directorio, tal como al crear o eliminar archivos nuevos en el directorio, o cambiar sus atributos, y guardar en memoria caché esos cambios.
