    摘要： This application discloses a data writing method, a data reading method, an apparatus, a device, a system, and a medium. A network controller performs erasure code encoding on original data, and writes a third quantity of target data blocks in a plurality of obtained target data blocks into a storage node. The network controller reads a first quantity of target data blocks in the third quantity of target data blocks from the storage node, and decodes the read target data blocks. The plurality of target data blocks include a first quantity of original data blocks and a second quantity of check data blocks, two ends of the target data block include same version information, and the third quantity is greater than the first quantity. In this application, computing overheads originally belonging to a central processing unit can be offloaded to the network controller, thereby reducing consumption of the central processing unit, improving data processing efficiency, and ensuring data validity by using the version information included at two ends of the target data block.

    摘要： This application provides a data processing method and apparatus. In this application, a computing device obtains first data, and determines a deduplication rate of the first data and a working status of the computing device. When the working status of the computing device is a busy state, if the deduplication rate of the first data is greater than or equal to a first preset value, deduplication on the first data is performed. In this way, the data deduplication rate can be ensured, and storage space occupied by the data can be reduced. If the deduplication rate of the first data is lower than the first preset value, deduplication is not performed on the first data, and the first data may be directly stored, to reduce consumption of a computing resource, back up as much data as possible, ensure a backup bandwidth, and increase a backup data amount.
