Abstract: The present disclosure relates to multi-core processors. One example multi-core processor includes a job manager and multiple processing cores coupled to the job manager. The job manager stores multiple job chains and dependency relationships between the multiple job chains. The job manager determines a first job chain and a second job chain in the multiple job chains based on the dependency relationships between the multiple job chains, where a dependency relationship between the first job chain and the second job chain is non-dependency. The job manager schedules a part or all of the multiple processing cores to execute one or more first tasks, and schedules at least one second task in the second job chain to at least one first processing core for execution when the at least one first processing core in the multiple processing cores is in an idle state.

Abstract: This disclosure provides a data processing method. The method includes: A backup server receives a metadata obtaining command, where the metadata obtaining command is used to obtain file system metadata in a first format, and the command includes an identifier of a to-be-read target directory. The backup server obtains, from a metadata storage area of an archive storage based on the identifier of the target directory, file system metadata that is in a second format and that corresponds to the target directory, converts the file system metadata that is in the second format and that corresponds to the target directory into file system metadata that is in the first format and that corresponds to the target directory, and returns the file system metadata.
