Abstract

Embodiments of the present disclosure relate to a method for managing backup data, an electronic device, and a computer program product. This method comprises: determining a number of times of space recycling operations that have been executed on a backup data block; determining, based on the number of times, a current popularity of the backup data block, the current popularity at least indicating a probability that the backup data block will be recycled in a to-be-executed space recycling operation; and moving, based on a determination that a former storage area where the backup data block is located does not correspond to the current popularity, the backup data block to a target storage area corresponding to the popularity. In this way, data with similar popularity can be managed in a more centralized manner, thereby reducing data rewriting caused by subsequent space recycling.
