FIG. 1 is a flow chart of a fast recovery method for an operating system according to an embodiment of the present invention;
fig. 2 is a structural 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 in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
Fig. 1 shows a flow of a fast recovery method for an operating system according to an embodiment of the present invention. Referring to fig. 1, the fast recovery method of an operating system includes:
and S11, restoring the backup operating system to the operating system used by the system to run.
And S12, recovering the key parameters which are significant to the operation of the operating system from the key parameter backup area.
And S13, setting the recovered key parameters as the key parameters used by the operation of the operating system.
And S14, operating the operating system according to the set key parameters.
The key of the technical scheme of the invention is to restore the original operating system and then recover the key parameters of the operating system. Since the parameters used by the recovered operating system in operation are all the key parameters originally used by the operating system, the operating state of the operating system is the same as that before the recovery operation is performed.
Since the running state of the operating system after the recovery operation is performed is completely the same as that of the previous operating system, our recovery operation recovers not only the operating system itself but also the running 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 the same for all users using the operating system, and are only related to the operation of the system. Such parameters may include: the system time.
The key parameters related to the user setting refer to a type of parameters whose values can be different for different users of the system. Such parameters may include: user password, interface display mode.
Typically, the update critical parameters may take the form of a download profile. That is, the values of the key parameters to be replied are stored in the form of configuration files, and then the configuration files in which the values are stored are downloaded to the local executing the recovery of the operating system, so that the recovery of the key parameters can be completed.
Furthermore, 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 a configuration file. And if the key parameter needing to be updated is found, performing key parameter recovery by using the key parameter value stored in the configuration file. And if the key parameter needing to be updated is not found, setting the value of the key parameter as a default value.
Still further, the default setting of the key parameter may also be performed according to a dependency relationship with the key parameter for which the recovery operation has been performed.
It should be understood that there is a dependency relationship between different critical parameters during a critical parameter recovery operation. For example, once the time zone parameter is set to the eighty-zone, the preferred system language option is most likely in chinese.
The default value may be set according to the dependency relationship of the values of the set key parameters. That is, when a default value of a key parameter is set, first, a search is performed to see whether a dependency relationship exists between the key parameter and a value of the set key parameter. And if the key parameter is stored, setting a new default value of the key parameter according to the set key parameter value and the dependency relationship between the key parameter value and the key parameter value. And if the key parameter has no dependency relationship with any set key parameter, directly setting the value of the key parameter 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 quick recovery system 200 may be used to act as an operating system recovery device in a computer system. As described herein, the fast recovery system 200 for an operating system may be used to implement recovery functionality 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 functionality of the fast recovery system 200 of the operating system may be implemented in multiple nodes in the network.
