1. A method for backing up data, comprising:
acquiring, by a system comprising a processor, data block deduplication information of source data and pieces of backup node deduplication information of backup nodes in a backup node set, wherein backup node deduplication information in the pieces of backup node deduplication information comprises data block deduplication information of backed up data in a corresponding backup node;
determining, based on the data block deduplication information of the source data and the pieces of backup node deduplication information, deduplication rates of the source data relative to the backup nodes in the backup node set, wherein a deduplication rate in the deduplication rates indicates a deduplication ratio of the source data when backing up the source data to the corresponding backup node; and
selecting, based on the deduplication rates for the backup nodes, a target backup node for backing up the source data from the backup node set.
