摘要： The present disclosure provides a network-based file cloud synchronization method, including: prior to file synchronizations between user terminals and a server, respectively creating file registration information tables for the multiple user terminals and the server, wherein the file registration information tables on the respective user terminals include identifiers of all files created by the respective user terminals and the file registration information table on the server includes identifiers of files already uploaded to the server; on the currently used user terminal, randomly scanning data of a to-be-synchronized file so as to obtain a random feature code to be stored; identifying whether the data of the to-be-synchronized file is consistent with the data of the synchronized file according to the two comparisons between the identifiers and the random feature codes and determining a whole file synchronization operation is performed, no synchronization is performed, or only an incremental synchronization operation is performed.
