Embodiment Construction

[0025] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, but not all of them. Based on the embodiments in the present application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present application.

[0026] The fault-tolerant method for data storage provided in the embodiment of the present application is applied to an embedded system. Through the pre-set program in the internal processor of the embedded system, when the embedded system is powered off, the system recovery is completed through the first backup data or the second back...

Abstract

The invention relates to the field of data processing, in particular to a fault tolerance method and device for data storage, equipment and a storage medium. The method comprises the steps that when the embedded system is powered on and started, whether the process of storing data to be backed up to a first storage space is completed or not is judged when the embedded system is powered off last time; if yes, first backup data stored in the first storage space are backed up to the second storage space, the first backup data are recovered to the embedded system, and the first backup data are to-be-backed-up data stored when the embedded system is powered down last time; if not, second backup data stored in the second storage space are recovered to the embedded system, and the second backup data are historical to-be-backed-up data stored before the embedded system is powered down last time. The data backup method and device are used for solving the problem that on the premise that the size of equipment is not increased, when the embedded system is powered down, the accuracy of backup data cannot be guaranteed, and then power-on recovery of the system is abnormal.

Description

technical field [0001] The present application relates to the field of data processing, and in particular to a fault-tolerant method, device, device and storage medium for data storage. Background technique [0002] In an embedded system, when the system is powered off, some data during system operation needs to be stored. When the embedded system is powered on again, the system can be restored through the data stored when the power was off. When the embedded system needs to store a large amount of data when it is powered off, the required storage time is longer. After the main power supply of the embedded system is powered off, it still needs to run for a long time to complete the data storage. [0003] In the prior art, when the embedded system is storing data, one way is to use the residual power of the capacitor or inductor in the embedded system to support the embedded system to save data when the embedded system is powered off. However, the duration of the residual p...
