Abstract: A data protection system and method apply to a computer device. The computer device links to a data protection system. The data protection system contains or links to at least two storage units. The data protection method partitions all the storage units into two blocks, and one block functions as an active memory zone, and another block functions as a backup memory zone. In each cycle of data backup, a portion of the operating storage units are backuped to the storage units in the backup memory zone. Then, the role of the storage units that have been backuped and the role of the storage units that have backuped data interchange with the active memory zone and the backup memory zone respectively having original numbers of the storage units. When one storage unit malfunctions, data can be retrieved from another storage unit and written back to the malfunctioning storage unit. In the present invention, the storage units alternately backup data.

Abstract: The present invention discloses a job-based structure using a process as a data processing and transmission unit. The structure includes a main system, and a disk array system. The main system includes an interface controller connected to the disk array system. The disk array system includes a job queue controller, a PRD table controller, a DMA controller and a storage device connected through a DMA bus. The DMA controller executes an instruction transmitted through the interface controller according to a request of the main system, and the instruction is decomposed into a number of processes for the job queue controller to access a storage device sequentially. The accessed data is transmitted to the job queue controller in terms of processes and responded to the main system sequential. Therefore the invention can improve the processing efficiency of the main system.

Abstract: The present invention discloses a microdisk array apparatus using semiconductor automated equipment, and the apparatus is installed into a space of a 3.5-inch IDE hard disk of the semiconductor equipment to substitute the hard disk directly. The apparatus includes a frame, and the frame has a connecting interface, a disk array controller and storage devices. During use, the semiconductor equipment stores, reads, updates and copies data with the storage devices through the connecting interface and the disk array controller. The storage device can be a 2.5-inch IDE hard disk or solid state disk. Since the IDE hard disk becomes a mainstream storage device of the semiconductor equipment, and the solid state disk has the quiet, fast, compact and long-life features, the apparatus is compatible to the storage devices of these two specifications, so as to provide better data storage and backup.
