The invention discloses a high-reliability file synchronization method based on log changes. The method comprises the steps of: judging whether a file requested to be operated is locked after a customer request is received by a file server, and waiting for unlocking to perform relevant operations if the file is locked; recording the operational type and the operational file of every modification through the file server in a log format; performing real-time scanning of the log file through the file server, and synchronizing all files to other nodes when the number of operational logs reaches the threshold value; and when the number of operational logs is smaller than the threshold value, sequentially processing every log file according to a sequence of generation time of the log files. For every log file, additional files are synchronized to other nodes according to contents of the operational log, and the operational log is deleted if synchronization is successful; and otherwise, the operational log is maintained. The target node is locked when files are synchronized, and the problem of file inconsistency caused by sudden switching of a host and a spare unit during file synchronization can be solved effectively.
