Abstract

Implementations of the present disclosure provide a method for backup destination selection, an electronic device, and a computer program product. In one method, in a storage device set, a first group of candidate subsets is obtained, and the number of storage devices included in candidate subsets in the first group of candidate subsets is determined based on the number of copies specified by a backup task. A first group of subset codes of the first group of candidate subsets is determined. A second group of subset codes is generated according to the first group of subset codes, and codes in the second group of subset codes uniquely identify the candidate subsets. Based on the first group of candidate subsets and a second group of candidate subsets corresponding to the second group of subset codes, a target subset is selected as a backup destination of the backup task. According to example implementations of the present disclosure, a corresponding apparatus, a corresponding electronic device, and a corresponding computer program product are provided. The implementations of the present disclosure can greatly reduce the amount of calculation for selecting the target subset, and thereby improving the automation level and performance of the storage system.
