Abstract
Embodiments of the present disclosure relate to a data backup method, a data backup device, and a computer program product. The method includes: determining delta data based on previous data and current data of a storage system; determining a delta data block subset in a delta data block set; sending delta index information and delta reference information associated with delta data blocks in the delta data block subset to a backup storage system; and sending, to the backup storage system, a further delta data block subset including delta data blocks in the delta data block set other than the delta data block subset. With the technical solution of the present disclosure, the amount of data transmission, the amount of computation, and the usage of a processing unit and a memory when backing up data can be reduced.
