The invention relates to a client file recovery method. The method comprises the steps of sending a mirroring request to a management server when a fault does not occur, thereby requesting to performfile mirroring; according to a file segmentation policy provided by the management server, performing file segmentation processing on files needed to be mirrored in a local end; performing segment mirroring on recovery end sets corresponding to segments Lj in sequence; and when the fault occurs, performing data recovery on a faulted client according to data stored in recovery ends. According to the method, parallel recovery can be automatically performed; recovery services of different levels are provided by considering the priority degrees of the files; the file recovery speed and security are improved by establishing a binding port and multiple recovery files; and the problems of simplicity and security shortage of an existing data recovery mode are solved.
