APPARATUS AND METHOD FOR STORING SNAPSHOT IMAGE

摘要

PURPOSE: A snapshot storage method and device are provided to store a snapshot in continued blocks of a non-volatile memory, thereby minimizing booting time of a system. CONSTITUTION: A preparation unit(111) prepares a snapshot in a main memory unit. A block assignment unit(112) receives a continuous reference block in a non-volatile memory unit. When the block assignment unit assigns the continuous reference block, a storage unit(113) stores the snapshot in the assigned continuous reference block. A swap table preparation unit(114) prepares storage information of the snapshot in a swap table and stores the same in the non-volatile memory unit. When the block assignment unit does not assign the continuous reference block, the block assignment unit receives variable continuous blocks in the non-volatile memory unit.
