Techniques involve: acquiring a first source snapshot for a source storage object stored in a source storage device; determining first difference data between the first source snapshot and the source storage object or a second source snapshot for the source storage object, creation time of the first source snapshot being associated with creation time of the second source snapshot; and sending the first difference data to a destination storage device to enable the destination storage device to create a first destination snapshot for a destination storage object stored in the destination storage device based on the first difference data. Such techniques can migrate snapshots more efficiently to improve storage management efficiency.

Techniques for disk failure control involve determining the number of failed disks in a Redundant Array of Independent Disks (RAID). The techniques further involve comparing the number of failed disks with a predetermined threshold; and in accordance with a determination that the number of failed disks exceeds the predetermined threshold, setting at least one non-failing disk in the RAID into a protection mode to prevent the at least one non-failing disk from being disconnected. Such techniques facilitate prevention of the user data loss in the RAID.
