A data storage system and the backup method thereof are provided. The data storage system includes a storage device and a storage controller. The storage controller is coupled to the storage device and used for dividing the storage device into a primary data block and a backup data block and setting the data storage system to operate under one of a real time backup mode and a non-real time backup mode. Under the non-real time backup mode, the storage controller backups the data stored in the primary data block to the backup data block when the data storage system is idle. |
