Abstract
The present disclosure relates to a method, device and computer program product for managing a backup job. Specifically, there is provided a method for managing a backup job, the backup job being used to store a data object to a storage system. In the method, the difference between the data object specified by the backup job and a copy of the data object in the storage system is determined. In response to determining the difference meets a predetermined threshold, a difference area in the data object where there might exist the difference is determined. With respect to a first block within the difference area, in a group of blocks in the data object, the backup job is processed based on a first query result from the storage system, the first query result indicating whether data in the first block differs from data in a corresponding block in the copy.
