The application provides a file fragment transmission method and device, a server, a medium and a program product, and relates to the technical field of big data. The method comprises the following steps: in response to a file fragment transmission request of a target file, a secure file transfer protocol (SFTP) session channel is established between the target file and a target storage server; when one file fragment corresponding to the target file is received, it is checked whether the information digest value of the file fragment is consistent with a preset information digest value, and when the information digest values are consistent, the file fragment is transmitted to the target storage server based on the SFTP session channel; when all file fragments of the target file are transmitted, when the first information digest total value of all file fragments matches the second information digest total value of the target file, the target file is obtained by combining all file fragments in the target storage server, and the SFTP session channel is closed. In the file dump process, the local disk IO overhead and the overall network overhead of the receiving server are effectively reduced.
