Drawings
The foregoing is merely an overview of the present invention, and the present invention is further described in detail below with reference to the accompanying drawings and detailed description.
FIG. 1 is a flowchart of a method for quickly recovering an operating system according to an embodiment of the present invention;
fig. 2 is a block diagram of a fast recovery system of an operating system according to an embodiment of the present invention.
Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present invention only, and are not intended to limit the present invention.
Fig. 1 shows a flow of a method for quickly recovering an operating system according to an embodiment of the present invention. Referring to fig. 1, the fast recovery method of the operating system includes:
s11, recovering the backup operating system into an operating system used by the system operation.
S12, recovering key parameters which are significant to the operation of the operating system by the key parameter backup area.
S13, setting the recovered key parameters as key parameters used by the operation system.
S14, operating the operating system according to the set key parameters.
The key of the technical scheme of the invention is that the original operating system is recovered first, and then the key parameters of the operating system are recovered. Because the parameters used by the restored operating system during operation are key parameters originally used by the operating system, the operating state of the operating system is identical to that before the restoration operation is performed.
Since the operating state of the operating system after the recovery operation is performed is exactly the same as that of the previous operating system, the recovery operation not only recovers the operating system itself, but also recovers the operating state of the operating system.
Typically, the key parameters may include: key parameters related to system operation, and key parameters related to user settings.
The key parameters related to the operation of the system are those that are the same for all users using the operating system, and are only related to the operation of the system. Such parameters may include: system time.
The key parameters related to the user settings refer to a class of parameters whose values can be different for different users of the system. Such parameters may include: user password, interface display mode.
Typically, updating the key parameters may take the form of a download profile. That is, the values of the key parameters to be recovered are saved in the form of configuration files, and then the configuration files with the saved values are downloaded to the local executing the recovery of the operating system, so that the recovery of the key parameters can be completed.
Further, after the transmission of the configuration file is completed, the recovery of the key parameters can be completed by searching the configuration file. Typically, the key parameters that need to be restored can be looked up in the configuration file. And if the key parameters needing to be updated are found, executing key parameter recovery by using the key parameter values stored in the configuration file. And if the key parameters which need to be updated are not found, setting the value of the key parameters as a default value.
Still further, the default setting of the key parameter may also be performed in accordance with a dependency relationship with the key parameter for which the restoration operation has been performed.
It should be appreciated that there is a dependency between different critical parameters during a critical parameter recovery operation. For example, once the time zone parameter is set to the east-eighth zone, the preferred system language option is most likely chinese.
The default value may be set according to the dependency relationship of the values of the key parameters already set. That is, when a default value of a key parameter is set, it is first searched to see whether there is a dependency relationship between the key parameter and the value of the key parameter that has been set. And if the key parameters are stored, setting the default values of the new key parameters according to the values of the key parameters which are already set and the dependency relationship between the key parameters. If no dependency exists between the key parameter and any key parameter which is already set, the value of the key parameter is directly set as the most original default value.
Typically, the file system running the operating system may be: jffs2, yaffs, cramfs, romfs, ramdisk, ramfs, or tmpfs.
Fig. 2 shows the structure of a quick recovery system of an operating system. Referring to FIG. 2, for example, the operating system fast recovery system 200 may be used to act as an operating system recovery device in a computer system. As described herein, the rapid recovery system 200 of an operating system may be used to implement recovery functions for an operating system in a computer system. The fast recovery system 200 of the operating system may be implemented in a single node or the functions of the fast recovery system 200 of the operating system may be implemented in multiple nodes in a network. Those skilled in the art will appreciate that the term operating system's quick recovery system includes devices in a broad sense, with the operating system's quick recovery system 200 shown in FIG. 2 being but one example. The fast recovery system 200 including an operating system is for clarity of description and is not intended to limit the application of the present invention to a particular operating system fast recovery system embodiment or to a class of operating system fast recovery system embodiments. At least some of the features/methods described herein may be implemented in a network device or component, such as the rapid recovery system 200 of an operating system. For example, the features/methods of the present invention may be implemented in hardware, firmware, and/or software running on hardware. The fast recovery system 200 of the operating system may be any device that processes, stores and/or forwards data frames over a network, e.g., a server, a client, a data source, etc. As shown in fig. 2, the fast recovery system 200 of the operating system may include a transceiver (Tx/Rx) 210, which may be a transmitter, a receiver, or a combination thereof. The Tx/Rx 210 may be coupled to a plurality of ports 250 (e.g., uplink and/or downlink interfaces) for transmitting and/or receiving frames from other nodes. Processor 230 may be coupled to Tx/Rx 210 to process the frame and/or to determine to which nodes to send the frame. Processor 230 may include one or more multi-core processors and/or memory devices 232, which may serve as data stores, buffers, and the like. Processor 230 may be implemented as a general-purpose processor or may be part of one or more application specific integrated circuits (application specific integrated circuit, ASIC for short) and/or digital signal processor (digital signal processor, DSP for short).
The above description is only of the preferred embodiments of the present invention, and is not intended to limit the invention in any way, and some simple modifications, equivalent variations or modifications can be made by those skilled in the art using the teachings disclosed herein, which fall within the scope of the present invention.
