The described technologies relate to efficient data collection. For instance, data collection information is generated based on a source data block and a target data block in a local data station. The data collection information is sent to a remote data station for data collection thereby based on the data collection information. In addition, data collection can be performed in the local data station based on the source data block and the target data block responsive to receiving a collection completion response from the remote data station. Since the size of the data collection information is much smaller than that of the valid data block, the amount of data sent by the local data station to other remote data stations is significantly reduced, thereby improving the performance efficiency of data collection and avoiding the impact of data collection on the storage performance of the local data station and other tasks.
