Abstract
The present disclosure discloses a data storing method, an apparatus, an electronic device and a readable storage medium, wherein the method includes: 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 that corresponds 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 the data of the internal source-tracing region to the external source-tracing region, to store the source-tracing information of the data region by the external source-tracing region. Therefore, the data may be accurately and efficiently recovered, and the reason for data loss is timely determined.
