    • Systems, methods and computer program products for efficiently re-starting and/or recovering interrupted synchronizations between a client and a server are described herein. A server transmits sync data to a client during a synchronization operation. The sync is interrupted for some reason prior to the client receiving all of the sync data. The client sends to the server a request to re-start the synchronization operation. The request includes information that identifies a point in the sync data that was received by the client prior to interruption of the sync. Such information may include (a) information identifying the last data received by the client prior to interruption of the sync; and/or (b) information identifying the next data needed by the client upon re-start of the sync. Thereafter, the server re-starts the sync by transmitting to the client the sync data starting from said point in said sync data identified by said request.
    • 这里描述了用于有效地重新启动和/或恢复客户机和服务器之间的中断的同步的系统,方法和计算机程序产品。 服务器在同步操作期间向客户端发送同步数据。 在客户端接收到所有同步数据之前,由于某种原因,同步被中断。 客户端向服务器发送重新启动同步操作的请求。 该请求包括标识在同步中断之前由客户端接收的同步数据中的点的信息。 这样的信息可以包括(a)在同步中断之前识别客户端接收的最后数据的信息; 和/或(b)识别重新开始同步时客户端所需的下一个数据的信息。 此后,服务器通过向所述客户端发送从所述请求所标识的所述同步数据中的所述点开始的同步数据来重新开始同步。
