The method may comprise acquiring metadata corresponding to to-be-recovered target data, the metadata comprising at least a first part of metadata corresponding to a first set of data blocks and a second part of metadata corresponding to a second set of data blocks. The method may further comprise acquiring, based on the first part of metadata, the first set of data blocks from a first backup storage device in a plurality of backup storage devices that store the target data. The method may further comprise acquiring, based on the second part of metadata, the second set of data blocks from a second backup storage device in the plurality of backup storage devices. In addition, the method may further comprise recovering the target data based on at least the first set of data blocks and the second set of data blocks. As such, the utilization of the backup storage devices can be improved and the time for data recovery can be shortened.
