Embodiment 1

[0065] This application discloses a system recovery method, which is applied to an electronic device in which a memory is provided. The system recovery method disclosed in the first embodiment is mainly applied to the system, see figure 1 As shown in the schematic diagram of the work flow, the system recovery method includes the following steps:

[0066] Step S11: After the system is started normally, it is judged whether the preset condition is satisfied, and when the preset condition is satisfied, a first instruction is generated, so that the memory collects the current system after receiving the first instruction. State file, and load the first identifier for the current system state file and store it.

[0067] Among them, judging whether the preset conditions are met include the following:

[0068] The first method is to determine whether the time since the normal start of the system or the time since the last time the system state file was stored has reached the preset time, an...

Embodiment 2

[0084] This application provides a system recovery method, which is applied to an electronic device in which a memory is provided. The system recovery method disclosed in the second embodiment is mainly applied to the system, see figure 2 As shown in the schematic diagram of the work flow, the system recovery method includes the following steps:

[0085] Step S11: After the system is started normally, it is judged whether the preset condition is satisfied, and when the preset condition is satisfied, a first instruction is generated, so that the memory collects the current system after receiving the first instruction. State file, and load the first identifier for the current system state file and store it.

[0086] Step S12: After an exception occurs and restart, it is determined whether the system needs to be restored according to the received user instruction, if yes, the operation of step S13 is performed, and if not, the operation of step S14 is performed.

[0087] Step S13. If ...

Embodiment 3

[0093] The third embodiment of the present application discloses a system recovery method, which is applied to an electronic device, and the electronic device is provided with a memory. The system recovery method disclosed in the third embodiment is mainly applied to memory, see image 3 As shown in the schematic diagram of the work flow, the system recovery method includes the following steps:

[0094] Step S21: The memory receives the first instruction transmitted by the system.

[0095] After the system is started normally, when the running state meets the preset condition, a first instruction will be generated, and the first instruction will be transmitted to the memory so that the memory can receive it.

[0096] Step S22: Collect the current system state file, load the first identifier for the current system state file, and store the current system state file loaded with the first identifier.

[0097] The memory after receiving the first instruction stores the current system stat...

Abstract

The invention relates to the field of electronic equipment and discloses a system recovery method, a device, a processor and storage. The system recovery method comprises the following steps: performing a judging operation after normally starting a system; generating a first instruction when the system is judged to meet a preset condition, and causing the storage which receives the first instruction to store a present system state file loaded with a first identifier; when the system is abnormal and restarted and the system recovery is required, acquiring the lastly stored system state file in the storage according to the first identifier and accordingly recovering the system. According to the system recovery method disclosed by the invention, the recurrence for a problem appearing environment in the mode of the prior art is not required during a system recovery process and the step is simple, so that the efficiency of the system recovery is increased; the backup for the system is realized; the system is recovered to the last normal state; the operation finished during the period from the normal starting to the abnormal appearance of the system is stored.

Description

Technical field [0001] The present invention relates to the field of electronic equipment, in particular to a system recovery method, device, processor and memory. Background technique [0002] When using PC (personal computer, personal computer) machines or other electronic devices, such as some embedded devices, system abnormalities or crashes may occur. In this case, it is necessary to restore the system with abnormal problems. [0003] In the prior art, there are mainly two ways to recover an abnormal system. One is to reproduce the environment where the problem occurred, that is, what operations the user performed before the system is abnormal, and when the problem environment is reproduced , You need to re-execute these operations in order; another system recovery method is to obtain the last time the system started normally, and restore the state of the system to that time. [0004] However, the inventor found in the research process of this application that when the first me...
