Data backup method based on user storing actions
A data backup and user data technology, which is applied to the redundancy in the operation for data error detection and response error generation, etc., which can solve the loss of data information, uneven busy and idle status of the production system, and inability to fully utilize the productivity of the production system. And other issues

Problems solved by technology
Its disadvantage is that if the timing policy is not set properly, the data information stored since the last backup may be lost
[0006] From the above analysis, we can see that the main bottleneck of current information system backup lies in the uneven busy and idle status of the production system, which cannot fully utilize the productivity of the production system. Therefore, how to perform data backup according to the current operating status of the production system and user storage behavior is a current research topic. hot issues

Embodiment Construction
[0057] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0058] Algorithm of the present invention is characterized in that:
[0059] There are m production systems and p backup systems (B 1 , B 2 ,...,B p ) and n users, when the production system has a production task, the system will execute the production task first; only when the production system is idle for more than the time threshold, the production system can perform data backup: during the implementation of data backup, The production system gives priority to backing up user data that exceeds the data volume threshold; only after the data exceeding the data volume threshold is backed up, and if the production system is still idle, backs up user data that does not meet the data volume threshold. Multiple users can use a production system to produce and generate data information at the same time; the data of a production system can be backed up to multiple ba...

The invention provides a data backup method based on user storing actions. The method is characterized in that the user storing activity feature is introduced into the data backup process of an informatization system, and data is quickly backup into a backup system in the optimum idling opportunity of the informatization system according to the key attributes of the user storing feature, the dynamic load characteristics of all servers in the production system, and the like, thereby satisfying the data backup requirement on the informatization system. The method can comprehensively considers the data backup information amount and the current resource using condition of the servers, and is used for carrying out data backup by fully using the idle time of the servers of the production system, thereby greatly enhancing the utilization rate of the server system, improving the storing efficiency and the practicality of the backup information, and decreasing the possibility of the data loss of the production system.
Description
(1) Technical field [0001] The invention relates to a fast data backup technology of an information system. (2) Background technology [0002] As the degree of informatization in our country is getting higher and higher, enterprises and institutions are increasingly dependent on information data and information systems. More and more disasters and threats may cause serious consequences in information system damage and business interruption. These disasters include natural disasters, man-made disasters and technological disasters. For key industries such as government, finance, telecommunications, civil aviation, railways, and electric power, the consequences of these disasters are not only economic losses in information systems, but may also cause social instability. For this reason, the disaster backup technology of information system (abbreviated as disaster backup) is proposed. [0003] The disaster recovery of the information system is to copy the data information of t...
