A method includes an encoder side that obtains a plurality of data blocks in batches, and encodes the data blocks. In an itime of encoding, after obtaining an incremental data block, the encoder side performs encoding processing on the incremental data block using erasure code to generate an incremental parity block, the incremental data block includes at least one data block, and i is an integer greater than 1. The encoder side performs an exclusive OR operation based on the incremental parity block and an original global parity block to generate a first incremental global parity block. The original global parity block is a first incremental global parity block generated by the encoder side in an (i−1)time of encoding, and an original data block is a data block obtained by the encoder side before the (i−1)time of encoding.
