Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

The security device usually has two backup systems, namely a complete system form and a small system form. The complete system is completely the same as the main system, has all functions of the main system and can work independently; the small system has only one upgrading function and is used for upgrading the main system software and repairing the main system software error to restore the normal operation of the system, and the small system has no other functions and cannot work independently. However, for a backup system in a complete system form, confusion of user use is easily caused, the main system is affected to different degrees in working use, and meanwhile, the backup system has the hidden danger that the backup system cannot work due to self upgrading or configuration parameter change, so that the meaning of the backup system is lost. For a backup system in a small system form, the system cannot be started due to configuration file or a certain knowledge base error, and the backup system does not have the complete capability of the backup system. Therefore, in terms of software backup in the security device, a better backup scheme capable of taking both backup capability and security into consideration is lacking at present. Based on this, the embodiment of the disclosure provides a software backup method and device.

Referring to a flowchart of a software backup method shown in fig. 1, the method may be applied to a security device, and the software backup method provided in this embodiment includes the following steps:

step S1, when the primary system fails, a backup system pre-stored in the security device is obtained. Wherein the backup system includes only one executable restore command.

In this embodiment, the backup system is only used when the main system of the safety device fails, and the failure of the main system includes: the main system can not start, log in, forget that the password of the administrator can not enter the system, and cause any faults that the main system can not start to work normally, such as program error, configuration error and other dependence deficiency. The backup system is used and needs to be selected to enter when the system is loaded, and the backup system in the embodiment accesses the safety device through the serial port of the safety device.

And starting or restarting the safety equipment under the condition that the backup system is connected with the safety equipment through the serial port.

Step S2, after the security device is started, the backup system is used to perform file recovery on the failed main system, so that the main system is restored to a factory state.

In practical application, after the security device is started, prompt information for entering the main system or the backup system is displayed on the display interface. When the selection operation of the user for the prompt information is not monitored, that is, the user does not select to enter the main system or the backup system, the security system defaults to enter the main system after the preset monitoring time duration is reached. And under the condition that the selection operation of the user for the prompt information is monitored, entering a main system or a backup system selected by the user according to the selection operation. It will be appreciated that in the event of a failure of the primary system, the selection operation is an operation to select entry into the backup system.

After entering the backup system, only one recovery command can be executed by the backup system, and other operations are not allowed to be carried out. Executing the recovery command, and performing file recovery on the failed main system by using the backup system, wherein in the process, the recovered files at least include but are not limited to: software program files, factory configuration files and dependent knowledge base. And restoring the file of the main system to restore the main system to a factory state.

For easy understanding, as shown in fig. 2, the present embodiment provides a specific method for performing file recovery on a failed primary system by using a backup system, including the following steps:

in step S201, the license file in the main system directory is copied to the temporary directory for storage. Since the license file is generated by registration after the secure device leaves the factory, the present embodiment copies the license file to the temporary directory and retains it, not in the restored file described above. Subsequently, upon recovery of the license file, the license file in the temporary directory may be copied to the main system directory.

In step S202, all files in the main system directory are deleted. And deleting all files in the main system directory, namely emptying the main system directory, wherein the main system is not existed after the step is completed.

In step S203, the system software compressed package in the pre-saved and backup system is expanded and copied into the main system directory. Specifically, a system software compressed package pre-stored in the backup system at the time of factory is used, and is expanded and copied in a main system directory, and the file contents in the system software compressed package include all the files to be restored, such as the software program files, the configuration files at the time of factory, and the dependent knowledge base.

Step S204, checking whether the files in the main system directory are successfully and correctly copied one by one.

Specifically, each file in the main system directory can be used as a current file one by one, and the current file is checked to ensure that the current file is copied successfully and correctly. If it is verified that the current file is not copied successfully and correctly, step S202 is performed, that is, the file that is not copied successfully and correctly in the main system directory is deleted. If the current file copy is verified to be successful and correct, the following step S205 is performed.

In step S205, the license file in the temporary directory is copied into the main system directory.

When the license file in the temporary directory is copied into the main system directory, the main system is reestablished, and the main system is restored to the system in a factory state.

After the failed main system is restored to the factory state according to the above steps, the following step S3 is executed.

In step S3, the operating system is started up with the main system restored to the factory state.

Thus, a complete software backup recovery process is completed.

In summary, the software backup method provided in the embodiment of the present disclosure includes: when the main system fails, the acquired backup system is used for carrying out file recovery on the failed main system, and then the main system which is recovered to the factory state is used for starting the operating system. In the technical scheme, the backup system only has one recovery command for recovering the main system to the factory state, and other operations are not allowed, so that the backup system is not allowed to be upgraded or updated, and the safety and reliability of the backup system are ensured. Meanwhile, the backup system has complete backup capability, and when any fault occurs in the main system, the backup system can be used for file recovery without returning to a factory for processing. Therefore, the software backup method provided by the embodiment effectively improves the problems and the defects of the existing backup system, so that the backup system can have complete backup capability, and the software backup method can ensure the safety and the reliability of the backup system and is not damaged or interfered.
