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.
