Abstract: In a backup method, a source storage device sends data to a backup storage device. The source storage device contains a processor and a cache. The processor receives a write data request which includes target data. And then, the processor reads a period ID recorded in a period ID table, wherein the period ID is corresponding to a first period. Next, the processor modifies the write data request by attaching the period ID to the target data and writes the modified write data request into the cache. After a backup task corresponding to the period is triggered, the processor obtains data received during the period corresponding to the period ID and sends the obtained data to the backup storage device.
Abstract translation: 在备份方法中，源存储设备将数据发送到备份存储设备。 源存储设备包含处理器和高速缓存。 处理器接收包含目标数据的写数据请求。 然后，处理器读取记录在周期ID表中的周期ID，其中周期ID对应于第一周期。 接下来，处理器通过将周期ID附加到目标数据来修改写入数据请求，并将修改的写入数据请求写入高速缓存。 在触发与该周期相对应的备份任务之后，处理器获取在与周期ID相对应的周期期间接收到的数据，并将获得的数据发送到备份存储设备。

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.
