The disclosed method for encoding an erasure code comprises the steps of: (a) generating a first local parity group including two or more local parity nodes for data nodes; (b) generating at least one global parity node for the data nodes; (c) generating at least one second local parity group including two or more local parity nodes for the data nodes; and (d) storing the data nodes, the first local parity group, the second local parity group, and the global parity node. According to the disclosed method, it is possible to store and recover data safely and efficiently.
