Abstract: An adaptive file storage method and apparatus is disclosed. The method includes determining a cold and hot attribute of a file, and performing coding storage processing or transcoding storage processing on the file according to the cold and hot attribute of the file. Therefore, a requirement of the cold and hot attribute of the file for storage overheads and restoration costs can be fully considered. In addition, the used coding technology has high reliability and a high coding speed. Therefore, comprehensive performance in multiple dimensions of storage overheads, restoration costs, reliability, and an coding speed can be improved.

Abstract: A data recovery method in a distributed storage system including a NameNode, a plurality of first storage nodes and a plurality of second storage nodes, where each of the first storage nodes includes a data processing apparatus communicatively coupled to the NameNode. The data processing apparatus receives a file block obtaining request carrying an identifier of a target file, determines that a target file block is lost according to the identifier of the target file, obtains, from the NameNode, an identifier of a target storage node on which a recovery dependence data block is located, and obtains the recovery dependence data block according to the identifier of the target storage node and the identifier of the target file to recover the target file block.
