Abstract

Embodiments of the disclosure provide a computer-implemented method for data replication from a first storage to a second storage. In the method, data replication control blocks for data blocks stored in the first storage and needed to be transmitted may be generated. The data replication control blocks may be sorted in an ascending order of probabilities of expected overwrites of the respective data blocks. The data blocks may be transmitted from the first storage to the second storage according to the sorted data replication control blocks.
