PURPOSE:To fast back up the cache data in a write-back cache system. CONSTITUTION:When a power supply is cut off, the block data on a block address 0 of a cache 12 are read out and written in a block address (k) of a disk 22 showing the head of an area A2. Then the block data on a block address 1 of the cache 12 are read out and written in a block address (k+1) of the disk 22. These operations are repeated thereafter. When a power supply is applied again, the block data on the address (k) of the disk 22 are read out and written in the address 0. Then the block data on the address (k+1) of the disk 22 are read out and written in the address 1 of the cache 12. These operations are repeated thereafter. |
