摘要： Aspects of the subject matter described herein relate to resource replication systems. In aspects, a mechanism is described that detects when local resources are stale. Local resources may be stale when the time between a last successful synchronization activity and a current time exceeds a staleness value. If the local resources are determined to be stale, the local member may refrain from certain synchronization activities until the local member is allowed to resume these certain synchronization activities. If the local resources are not stale, additional synchronization activities including synchronizing resources between the member and an upstream or downstream partner may be performed.
摘要翻译：本文描述的主题的方面涉及资源复制系统。在一些方面，描述了一种机制来检测当地资源何时陈旧。当最后一次成功的同步活动与当前时间之间的时间超过了平淡度值时，本地资源可能会过时。如果当地资源被确定为陈旧，当地成员可以避免某些同步活动，直到允许当地成员恢复这些某些同步活动。如果本地资源不是过时的，则可以执行包括在成员和上游或下游伙伴之间同步资源的附加同步活动。

摘要： Aspects of the subject matter described herein relate to resource replication systems. In aspects, a mechanism is described that maintains replicated resources on a slave member that participates in a replica group. The slave member detects that a local resource has been updated locally. If the resource was created locally in the update, the slave member deletes the local resource. Otherwise, the slave member determines an upstream partner from which to install a replacement resource and then installs the replacement resource. In aspects, this behavior undoes local updates to local resources that occur on the slave member.
摘要翻译：本文描述的主题的方面涉及资源复制系统。在各方面中，描述了在参与副本组的从属成员上维护复制资源的机制。从属组件检测到本地资源已被本地更新。如果在更新中本地创建资源，则从属组件会删除本地资源。否则，从属成员确定要从其安装替换资源的上游伙伴，然后安装替换资源。在这方面，此操作会撤消对从属成员发生的本地资源的本地更新。

摘要： 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.

摘要： A backup file is generated to capture the current state of a computer. The computer state may be restored to the computer in a hybrid manner at a later time by accessing some files and/or data included in the backup file and downloading other files contained in a list in the backup file. By listing some files rather than including the actual files in the backup file, the backup file may be generated faster and require less processing and memory resources. When the computer state is restored, secondary files and computer state data contained in the backup file are installed to the computer. A list of primary files in the backup file is accessed, each primary file is retrieved from one or more remote publishers over a network, and the retrieved primary files are installed.

摘要： Aspects of the subject matter described herein relate to shutdown recovery for resource replication systems. In aspects, a mechanism is described in which a machine having replicated data thereon can recover from a dirty shutdown. First, the machine determines whether a dirty shutdown has occurred. If so, the machine automatically performs shutdown recovery by causing resource metadata stored by the machine to be consistent with resource data stored by the machine. This may involve fixing the resource metadata for updates to the resource data that were not flushed to disk or may involve deleting the resource metadata and restoring it from another machine replicating the data.

摘要： Automatic file replication and scanning for malware in a sharing environment is based on detection of file system changes. Only one client of the multi-client environment needs to include malware protection software for all clients to benefit. A file replication service for each client monitors a shared directory, and synchronizes files across clients at the file system driver level. When a new file appears in the shared directory of a client system, through this driver, the new file automatically gets replicated. A malware protection component operates by monitoring the directory for new or modified files. File replication causes automatic malware scanning on the client that has protection. When the file has been cleaned and re-written to the directory, the replication service senses that the file has changed and replicates the cleaned file to the other clients. Thus, the replication behavior produces a multiparty file scanning and cleansing protection scheme.
摘要翻译：在共享环境中自动文件复制和扫描恶意软件是基于文件系统更改的检测。多客户端环境中只有一个客户端需要包含所有客户端的恶意软件保护软件才能受益。每个客户机的文件复制服务器监视共享目录，并在文件系统驱动程序级别跨客户机同步文件。当一个新文件出现在客户端系统的共享目录中时，通过该驱动程序，新文件将自动被复制。恶意软件保护组件通过监视新的或修改的文件的目录来运行。文件复制会在具有保护的客户端上自动进行恶意软件扫描。当文件已被清理并重新写入目录时，复制服务会检测到文件已更改，并将清除的文件复制到其他客户端。因此，复制行为产生多方文件扫描和清理保护方案。

摘要： 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.

摘要： 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.
