Abstract

Techniques for storage management involve determining, based at least on an upper limit duration for recovering a predetermined number of disk sets among a plurality of disk sets, a first recovery rate for recovering at least a portion of the plurality of disk sets. The techniques may further involve determining the number of disk sets that are not recovered based on the first recovery rate among the plurality of disk sets. In addition, the techniques may further involve performing data recovery on unrecovered disk sets among the plurality of disk sets based on a predetermined second recovery rate according to the determined number being less than or equal to the predetermined number, the second recovery rate being lower than the first recovery rate and being associated with the upper limit duration. Accordingly, it can be ensured that all to-be-recovered disk sets may be recovered within a recovery duration.
