Problems solved by technology

The disadvantage of this design is: if the system state changes a lot, a large number of file operations will occur, and the reliability of the system is greatly affected by the reliability of the file system; state storage in files has many limitations, such as how to delete status etc.; lower performance
The traditional system state backup and recovery implementation relies on the file system, which has low performance and poor stability, which reduces the reliability of the system

Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] First refer to figure 1 Further explain the dual backup mechanism of buying that part. like figure 1 as shown,

[0043] ● System current status area: save the real-time status data of the system, restore the status from the system status recovery area as needed.

[0044] ●System state backup area: usually in the shared memory, the system state is backed up in a defined format.

[0045] ●System state backup file: store the data in the system state backup area.

[0046] ●System state recovery area: extract the backup system state data and generate system state recovery data.

[0047] lik...

Abstract

The invention discloses a method for achieving high reliability of a stand-alone system based on a data dual-backup mechanism. The data dual-backup mechanism comprises real-time state backups based on a shared memory and condition backups based on a file system. The method for achieving high reliability of a stand-alone system based on the data dual-backup mechanism has following beneficial effects: backup and restoration of system states can be achieved at a quicker pace so that access to a file system is greatly reduced; and performance and stability of the system are improved so that system reliability is better achieved.

Description

technical field [0001] The invention relates to the field of system state backup and recovery, in particular to a system state backup and recovery method based on a double backup mechanism. Background technique [0002] For a stand-alone embedded system, in order to achieve fault recovery, it is necessary to back up key data and status during system operation. When the system fails and recovers, these status data can be restored to the running system, thus ensuring the continuous normal operation of the system. [0003] The most common implementation is to store the state data to a file, and restore the state from the file after the system restarts. The disadvantage of this design is: if the system state changes a lot, a large number of file operations will occur, and the reliability of the system is greatly affected by the reliability of the file system; state storage in files has many limitations, such as how to delete status, etc.; lower performance. The traditional sy...
