Abstract
The present disclosure provides a method and an apparatus for storing data and a method and an apparatus for recovering data, where the method of recovering data may include: reading partial check data and partial data corresponding to to-be-recovered data from prestored data, where the partial check data is obtained by coding entire data of the to-be-stored data based on a partial generator matrix, the partial generator matrix is obtained by dividing a row of an entire generator matrix and rows of the partial generator matrix which are obtained by dividing include a zero element; and recovering the to-be-recovered data based on the read partial check data and partial data. The examples of the present disclosure can reduce read data volume during data recovery and further reduce I/O consumption substantially.
