1. A data storing method, comprising:
constructing a data region and an external source-tracing region in a magnetic disk of a distributed storage system in advance, wherein the data region and the external source-tracing region have a corresponding relation, and in an internal memory, simultaneously constructing an internal source-tracing region corresponding to the external source-tracing region;
when it is detected that the data region is written with a target datum, writing source-tracing information corresponding to the target datum into the internal source-tracing region; and
downwardly swiping data of the internal source-tracing region to the external source-tracing region, to store source-tracing information of the data region by the external source-tracing region.
