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.
摘要翻译：本文描述的主题的方面涉及在资源复制系统中复制初始内容。在方面，参与副本组的每个成员从目录服务获得内容集状态。内容设置状态指示成员是否被允许与参与副本组的另一成员同步资源。如果该成员被指定为主要成员，则该成员可以向其下游合作伙伴复制资源。如果成员未被指定为主成员，则成员可能无法向下游合作伙伴复制资源，直到其成功与上游合作伙伴同步资源。可以设置栅栏值，以控制哪些资源在同步期间获胜（并被复制出来）。

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： 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 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： A block based backup system may store backed up data from multiple clients by maintaining backup databases for each client, where each backup database may include blocks of data. The backup system may perform a de-duplication process by examining the databases to identify common blocks and moving the common blocks to a common database. The common blocks may be removed from the client backup databases and a pointer substituted for the data, thus compacting the client backup databases. The de-duplication operation may be performed at an opportunistic time, such as after the clients have completed any data transfer to the backup system.
摘要翻译：基于块的备份系统可以通过维护每个客户端的备份数据库来存储来自多个客户端的备份数据，其中每个备份数据库可以包括数据块。备份系统可以通过检查数据库来识别公共块并将公共块移动到公共数据库来执行重复数据删除过程。可以从客户端备份数据库中删除公共块，并将指针替换为数据，从而压缩客户端备份数据库。重复数据删除操作可以在机会时间执行，例如在客户端完成对备份系统的任何数据传送之后。
