Abstract
Backing up data is described. An example method includes acquiring data block deduplication information of source data and pieces of backup node deduplication information of backup nodes in a backup node set. Then, based on the data block deduplication information and the pieces, deduplication rates of the source data are determined relative to the backup nodes in the backup node set. In addition, based on the deduplication rates for the plurality of backup nodes, a target backup node is selected for backing up the source data from the backup node set. Data features of the to-be-backed-up source data are utilized to determine the deduplication rate of the source data relative to each backup node, thereby selecting the target backup node through the deduplication rates of the backup nodes. The space occupation of backup nodes can also be reduced when backing up the source data, thereby achieving better space utilization.
