摘要：A method is provided for storing data by distributing the data into pluralstorage units that are accessible independently of one another. The method includes thesteps of dividing data to be stored into plural data blocks, generating parity datacorresponding to the data blocks, distributing the plural data blocks and the parity data

into the storage units to let the storage units store the same, responding to a situationwhere any of the storage units becomes inaccessible, reconstructing data stored in thestorage unit that has become inaccessible before the situation occurs based on datastored in the remaining storage units, dividing the reconstructed data into pluralreconstructed data blocks, generating parity data corresponding to the reconstructeddata blocks, and distributing the plural reconstructed data blocks and the parity datacorresponding thereto into accessible storage units to let the accessible storage unitsstore the same.
