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： 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： 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 replicating initial content in resource replication systems. In aspects, each member participating in a replica group obtains a content set state from a directory service. The content set state indicates whether the member is allowed to synchronize resources with another member participating in the replica group. If the member is designated as a primary member, the member may replicate out resources to its downstream partners. If a member is not designated as a primary member, the member may not replicate out resources to its downstream partners until it has successfully synchronized resources with an upstream partner. Fence values may be set which control which resources win (and are replicated out) during synchronization.

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： 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.
