Abstract: Embodiments of this application disclose a chunking method and an apparatus for implementing the method. According to the method provided in the embodiments of this application, a first data segment of a first length may be determined starting from a header of a to-be-chunked data flow, a data distribution characteristic of the first data segment is determined based on character values of all characters in the first data segment, and then a chunking position is determined for different data distribution characteristics by using different methods. In this way, a data flow can be better chunked, so as to enhance a deduplication effect.
