SYNCHRONIZATION SYSTEM FOR MULTIPLE CLIENT DEVICES

摘要

Systems and methods are disclosed for synchronizing one or more user data sets on one or more client devices of a user, using a synchronization system. Each client device can have two independent and asynchronously-operating synchronization engines. The synchronization system can include a synchronization system manager that can resolve conflicts in data that arise from different versions of software being used generate a data set. Each client can maintain two separate databases: a first database that can contain a snapshot of the state of the user data sets across client devices, as known to the synchronization system. The second database can contain a snapshot of the local file system and information about the state of synchronization of the local file system with the synchronization system.

1. A computer-implemented method, comprising:
receiving, from a synchronization service, by a client device of a user utilizing a first synchronization engine, a first snapshot of user data stored by a remote storage service; storing the first snapshot of the user data in a first database on the client device; updating a file system on the client device to reflect one or more differences between the user data on the remote storage and the file system, as indicated in the first snapshot; generating a second snapshot of the user data from the file system on the client device; storing the second snapshot in a second database on the client, the second database different from the first database; and transmitting the second snapshot in the second database on the client to the remote storage service, utilizing a second synchronization engine, for processing by the synchronization service, wherein the first synchronization engine and the second synchronization engine operate independently and asynchronously from one another.
