摘要： A system of creating logical volume and method thereof is used to solve the problems such as creation steps are complicated, a space of storage medium is wasted and the number of snapshots to be created is limited. An available logical volume space and a timestamp storage area are allocated in the logical volume according to space allocation algorithm. According to original data and data amended at subsequent time point in the logical volume, copy-on-write operation is sequentially performed on the amended data in the logical volume to create a timestamp corresponding to the time point. The timestamp of the corresponding time point is stored in the timestamp storage area. A storage medium offset address pointer is created to record writing position of the copy-on-write operation of the corresponding time point. And the pointer is stored in the storage medium to serve as index information of address of each timestamp.

摘要： A system and method for updating dirty data of designated raw device is applied in Linux system. A format of a command parameter for updating the dirty data of the designated raw device is determined, to obtain the command parameter with the correct format and transmit it into the Kernel of the Linux system. Then, a data structure of the designated raw device is sought based on the command parameter, to obtain a fast search tree of the designated raw device. Finally, all dirty data pages of the designated raw device are found by the fast search tree, and then are updated into a magnetic disk in a synchronous or asynchronous manner. Therefore, the dirty data of an individual raw device can be updated and written into the magnetic disk without interrupting the normal operation of the system, hereby ensuring secure, convenient, and highly efficient update of the dirty data.

摘要： A file data restoring system and method of a computer operating system and software thereof are applied in the installation of an operating system into a client computer. Divide the file data corresponding to the operating system into data blocks according to an appointed data size. Generate a check code for each of the data blocks to form a sequence list of original check codes and a sequence list of target check codes. Compare the sequence list of original check codes with the sequence list of target check codes, after installing the operating system into the computer. If the comparison result is inconsistent, a restoring call information is sent out. The position of the inconsistent check code is acquired through the restoring call information and the comparison result. The original file data corresponding to the position of the check code is read and restored to a corresponding target file.

摘要： A network packet capturing method for capturing a plurality of packets from a physical layer to an application layer by a network server through a network card is described. The packet capturing method includes the following steps. Capture packets by a new application interface (NAPI); set a ring queue in a kernel; provide a hook process for capturing the packets; store the captured packets into the ring queue; and map the packets stored in the ring queue into a memory space of a corresponding application through memory mapping, thereby reducing the number of interrupts of the system and the number of replications during the packets parsing.
