摘要： Various embodiments introduce the notion of a replication entity which implements a highly scalable file replication system. In one embodiment, the replication entity resides in the form of a scalable replication service. In at least some embodiments, the replication service provides a “drive in the sky” facility that can be used by individuals, such as subscribers, to synchronize their individual machines, such that their files are automatically replicated to a safe and always-on location. Alternatively or additionally, individuals such as subscribers can also access their files via a web-based interface when they are away from their machines.

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.
摘要翻译：本文描述的主题的方面涉及用于资源复制系统的关闭恢复。在一些方面，描述了一种机构，其中具有复制数据的机器可以从脏关闭恢复。首先，机器确定是否发生脏关闭。如果是这样，机器将通过使机器存储的资源元数据与机器存储的资源数据一致，自动执行关机恢复。这可能涉及将用于更新的资源元数据修复到未刷新到磁盘的资源数据，或者可能涉及删除资源元数据并将其从复制数据的另一个机器恢复。

摘要： The present invention is used to update objects over limited bandwidth networks. Objects are updated between two or more computing devices using remote differential compression (RDC) techniques such that required data transfers are minimized. In one aspect, efficient large object transfers are achieved by recursively applying the RDC algorithm to its own metadata; a single or multiple recursion step(s) may be used in this case to reduce the amount of metadata sent over the network by the RDC algorithm. Objects and/or signature and chunk length lists can be chunked by locating boundaries at dynamically determined locations. A mathematical function evaluates hash values associated within a horizon window relative to potential chunk boundary.

摘要： Aspects of the subject matter described herein relate to replicating resources across machines participating in a replica set. In aspects, a downstream machine requests that an upstream machine notify the downstream machine when updates to resources of the replica set occur. When such updates occur, the upstream machine notifies the downstream machine. In response thereto, the downstream machine requests resource meta-data and may include a limit as to how much resource meta-data may be sent. The upstream machine responds with the requested resource meta-data. Thereafter, the downstream machine determines which data associated with the updated resources to request and requests such data.

摘要： A method and system are related to updating objects over limited bandwidth networks. Objects are updated between two or more computing devices using remote differential compression (RDC) techniques such that required data transfers are minimized. In one aspect, efficient large object transfers are achieved by recursively applying the RDC algorithm to its own metadata; a single or multiple recursion step(s) may be used in this case to reduce the amount of metadata sent over the network by the RDC algorithm. Objects and/or signature and chunk length lists can be chunked by locating boundaries at dynamically determined locations. A mathematical function evaluates hash values associated within a horizon window relative to potential chunk boundary. The described method and system is useful in a variety of networked applications, such as peer-to-peer replicators, email clients and servers, client-side caching systems, general-purpose copy utilities, database replicators, portals, software update services, file/data synchronization, and others.

摘要： Peer devices register with a resource locator service so that the peer devices can be uniquely identified in a networking environment. An addressing scheme addresses a peer resource in the networking environment based on the unique identifier of a peer device that is a master publisher of the resource. Based on the addressing scheme, the resource locator service can track the location of the master publisher of the resource as well as additional locations of peer devices that have cached the resource and made it available. In various embodiments, the resource locator service can service requests for peer resources by providing a list of locations where the resource is expected to be available or, in the case of non-compatible requester, provide access to the resource itself.

摘要： A resource naming service (RNS) server receives peer resource requests from peer platforms through a networking environment. The RNS server, possibly in cooperation with other RNS servers and peer registrars generates a response to the request to enable the peer platforms to access the requested peer resources. In one embodiment, a response includes a list of locations of peer devices in the networking environment where a resource is expected to be available. A requesting device can then choose to access the resource from one or more of the listed peer locations.

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.
