    • A snapshot mechanism of a data processing system is provided herein. The snapshot mechanism includes providing a snapshot storage unit for storing the data created when snapshotting the target storage units and generating a plurality of snapshot images accordingly. Two different types of address tables in the snapshot image are used for corresponding to the storage units of the snapshot storage unit and the target storage units. The status of the target storage units can be recovered to the status at a predetermined time ago according to the snapshot images. The two types of address tables are respectively used for storing the data created by the data processing system and history data so as to prevent the data stored in the target storage units to be overwritten.
    • 本文提供了数据处理系统的快照机制。 快照机制包括提供快照存储单元,用于存储当对目标存储单元进行快照时创建的数据并相应地生成多个快照图像。 快照图像中的两种不同类型的地址表用于对应于快照存储单元和目标存储单元的存储单元。 目标存储单元的状态可以根据快照图像在预定的时间恢复到状态。 两种类型的地址表分别用于存储由数据处理系统创建的数据和历史数据,以防止存储在目标存储单元中的数据被重写。
