摘要： The subject invention relates to systems and/or methods that perform an authoritative and/or a non-authoritative restore of items in a data store. Backups are provided that include data associated with items and metadata related to the items that can include a history of operations and previous synchronizations to enable replications to converge after restoration. The operations that can be performed on the items include, for example, create, delete, update, move, etc. The items in the backups can be restored along with the metadata, which can be utilized to enable synchronization partners to converge based on a desired type of restoration.

摘要： Various embodiments of the present invention are directed to synchronization utilizing one or more optimizations through the utilization of metadata. For several embodiments of the present invention, one method for optimizing synchronization is to reduce the overhead required for said synchronization by having each peer only tracking changes for itself and other peers within its change community (or communities) (a.k.a., “Intra-Community-Only Change Tracking Optimization”). For certain embodiments of the present invention, another method for optimizing synchronization is to not create synchronization overhead until required. For numerous embodiments of the present invention, yet another method for optimizing synchronization is to minimize redundant use of a partner's unique global ID—a large and cumbersome number—and to instead maintain a table that cross-references each partner (and its unique global ID) with a smaller and much less cumbersome partner key.
摘要翻译：本发明的各种实施例涉及通过利用元数据利用一个或多个优化的同步。对于本发明的几个实施例，用于优化同步的一种方法是通过使每个对等体仅跟踪其变化社区（或社区）（或社区）内的其他对等体（也称为“共同体内社区”）来减少所述同步所需的开销，只有更改跟踪优化“）。对于本发明的某些实施例，用于优化同步的另一种方法是在需要之前不产生同步开销。对于本发明的许多实施例，用于优化同步的另一种方法是最小化伙伴的唯一全局ID（冗余和繁琐的数量）的冗余使用，并且替代地维护交叉引用每个伙伴的表（及其唯一的全局ID ）具有更小和更少的繁琐的合作伙伴密钥。

摘要： Systems and methods for replicating replicas in a sync community. Each replica in the sync community stores knowledge that represents changes the replica is aware of. Because each replica has its own knowledge, each replica does not need to know how many replicas are in the sync community or the topology of the sync community. By sending the knowledge with a request for changes, a replicating replica can enumerate the changes to replicate by comparing its knowledge with the received knowledge. After replication, the knowledge is updated. Knowledge may also include made-with-knowledge change IDs that permit each resolution to identify what a replica was aware of when a particular change was made. The made-with-knowledge values are used to detect conflicts during replication.

摘要： Tombstones can be removed from a data store without data corruption. Tombstones placed into a forgotten knowledge list can be compared against each other and/or items in a tombstone table, and deleted when tombstones representing subsequently deleted items are extant. Also, creation database version information can be kept along with database items, and databases can record database version information when they synchronize. If a synchronizing database discovers an item that it does not have, but the creation database version information associated with the item reflects that the synchronizing database “should” have the item, then it can be inferred that the item was subsequently deleted, and item resurrection can be prevented.

摘要： A uniform data structure contains a number of data fields. Some of the data fields are dedicated to contain information concerning the transfer of a data segment of a particular type (such as an XML segment) using one particular transfer mechanism (such as transferring as a string or DOM object, or transfer using an interface such as ISAXContentHandler, ITextSource, ITextSink, or IDOMSink interfaces). Other data fields are dedicated to contain information concerning the transfer of data segments of the same particular type using another transfer mechanism. When a module is to transfer a data segment, the module will cause the unified data structure to be altered as appropriate for the desired transfer mechanism.
摘要翻译：统一的数据结构包含多个数据字段。一些数据字段专门用于包含有关使用一种特定传输机制（例如转换为字符串或DOM对象，或使用接口等传输的特定类型的数据段（例如XML段））的传输的信息作为ISAXContentHandler，ITextSource，ITextSink或IDOMSink接口）。其他数据字段专门用于包含关于使用另一传送机制传输相同特定类型的数据段的信息。当一个模块要传输一个数据段时，该模块会使统一的数据结构根据所需的传输机制进行更改。

摘要： Caching mechanisms in which when a request to operate on particular identified network data is detected, the mechanism refers to a set of rules to determine whether to operate on a local copy of the identified network data, and whether to operate on the actual network data over the network. The set of rules are at least partially set by a human such as a user or network administrator, or perhaps by an application. The caching mechanism may optionally even block local read operations until the network data is synchronized with the remote copy of the network data. The mechanism may also block local write operations until synchronization is performed and/or the write operation is performed on the remote copy of the network data.
摘要翻译：当检测到对特定识别的网络数据进行操作的请求时，该机制是指一组规则来确定是否对所识别的网络数据的本地副本进行操作，以及是否对实际的网络数据进行操作网络。该组规则至少由人（例如用户或网络管理员）或可能由应用程序至少部分设置。高速缓存机制可以可选地甚至阻止本地读取操作，直到网络数据与网络数据的远程副本同步。该机制还可以阻止本地写入操作，直到执行同步和/或对网络数据的远程副本执行写入操作。

摘要： A system and method for synchronizing a database having metadata and raw data. Metadata may be fully synchronized between two systems, with copies stored on both systems. Raw data may be selectively synchronized, so that a client system need not store all of the raw data locally. When disconnected, the client system may identify certain portions of the raw data to store locally, and such data may be synchronized when reconnected to a server system.
摘要翻译：一种用于同步具有元数据和原始数据的数据库的系统和方法。元数据可能在两个系统之间完全同步，副本存储在两个系统上。可以选择性地同步原始数据，使得客户端系统不需要在本地存储所有原始数据。当断开连接时，客户端系统可以识别原始数据的某些部分在本地存储，并且当重新连接到服务器系统时，这些数据可以被同步。

摘要： Disclosed are systems and methods pertaining to data synchronization and move handling support. In particular, a move log is maintained that identifies data that has moved in, out, and within a synchronization scope. Furthermore, the log comprises times associated with when data moves in and out of the synchronization scope. Systems and methods can interact easily with the generated and updated move log to facilitate determining data versions and identifying new data that may need to be synchronized.
