The method comprises: obtaining time information related to a removal time point for a backup storage system, the time information indicating that a chunk in the backup storage system whose expiration time does not exceed the removal time point is to be removed; determining, from a removal period list, a target removal period whose end time does not exceed the removal time point, each removal period in the removal period list being mapped to at least one chunk element, the at least one chunk element representing at least one chunk in the backup storage system whose expiration time is within the removal period to which the at least one chunk element is mapped; determining at least one target chunk element to which the target removal period is mapped; and removing, from the backup storage system, at least one target chunk corresponding to the at least one target chunk element. Therefore, with this solution, expired chunks can be efficiently removed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, device, and computer program product for storage management","description":"Embodiments of the present disclosure provide a method, a device and a computer program product for storage management.
