Embodiments of the present disclosure provide a storage management method, an electronic device, and a computer program product. The method includes determining at least one count corresponding to at least one data segment of a file in a file set, the file set being stored in a local storage device, and the at least one count indicating the number of occurrences of the at least one data segment in the file set. The method further includes determining a deduplication ratio of the file based on the at least one count, the deduplication ratio indicating an overlapping level of the file with other files in the file set. The method further includes migrating the file from the local storage device to a remote storage device according to a determination that the deduplication ratio of the file is lower than a threshold.
