Abstract: Embodiments of the present invention provide a data processing device and a data processing method. In the data processing device and the data processing method provided by the embodiments of the present invention, first data in a memory is written into a first non-volatile storage unit in a log file form, and a log file of the first data written into the first non-volatile storage unit is written into a second non-volatile storage unit. Because a data write speed of the first non-volatile storage unit is higher than a data write speed of the second non-volatile storage unit, fast backup of the data in the memory can be achieved, and when the data in the memory is lost in an abnormal situation, security of the data in the memory can be ensured.

Abstract: A data loading method and device, where the method includes obtaining a data loading request of a virtual machine after the virtual machine is started, the data loading requesting to load target data in an image file, determining whether the target data is stored in a volume and a snapshot corresponding to the virtual machine, where the snapshot is obtained based on a blank volume corresponding to the virtual machine when the virtual machine is created, writing the target data from a mirror server into the snapshot when the target data is not stored in the volume or the snapshot, reading the target data and transferring the target data to the virtual machine, obtaining virtual machine data generated by the virtual machine, and writing the virtual machine data into the volume. Hence, a conflict between new data and old data in a data loading process is resolved.

Abstract: A data copy management apparatus and a data copy method thereof. The data copy method includes obtaining, using a hash algorithm, hash values of multiple source data blocks obtained by dividing source data; sending the hash values to a target storage side, so that the target storage side determines, based on the received hash values, whether the target storage side directly generates the source data blocks or a source storage side sends the source data blocks to the target storage side; ignoring the source data blocks when a first feedback fed back by the target storage side is received; and sending the source data blocks to the target storage side when a second feedback fed back by the target storage side is received. Thus, a speed of copying a special data block can be improved, saving central processing (CPU) and network resources and reducing copy time.
