Abstract
A data replication method and a storage system are provided. The method is applied to a storage system including a first storage device and a second storage device. According to the method, after determining replication information, a first storage system determines a first replication sub-information and a second replication sub-information according to the replication information, where the replication information is used to indicate data that needs to be replicated by the first storage system to a second storage system in a current replication task. Then, the first storage device replicates data to the second storage system according to the second replication sub-information, and the second storage device replicates data to the second storage system according to the second replication sub-information. According to the data replication method, efficiency of replication performed between the first storage system and the second storage system can be improved.
