SECURE SYNCHRONIZATION OF FILES

摘要

A copy of a first file may be stored in a first instance of a file space associated with a user of a first client device. An event is generated for a first modification of the first file and the event is sent to a server. A current revision number of the file space is obtained from the server, and the current revision number is compared to a past revision number corresponding to a last time files were synchronized to the first client device. In response to a determination that the current revision number is higher than the past revision number, a number of events that have occurred to the file space are requested from the server, the number of events corresponding to a difference between the current revision number and the past revision number. The first instance of the file space is updated based on the events.
