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] A data backup method based on user storage behavior is characterized in that: 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 give priority to executing the production task; only when the production system M i Idle time T for (i∈[1,m]) i greater than the time threshold θ i When , the production system performs data backup: for the production system M i User collection UM on i Check the data to be backed up of all users in the database; if the user U j (U j ∈UM i ) the amount of data to be backed up exceeds the data amount threshold λ i , user U will be backed up first j The data to be backed up goes to the designated backup system BM i Medium; when exceeding the data volume threshold...

Abstract

The invention provides a data backup method based on user storage behavior. The key of the present invention is to introduce the user storage behavior characteristics into the data backup process of the information system. This method can select the best idle time of the information system according to key attributes such as the user storage characteristics and the dynamic load characteristics of each server in the production system. The data is quickly backed up to the backup system to meet the data backup needs of the information system. The data backup method based on user behavior can comprehensively consider the amount of data backup information and the current resource usage of the server, and make full use of the idle time of the server in the production system for data backup, thereby greatly improving the utilization rate of the server system and improving the storage efficiency of backup information and practicality, and reduces the possibility of data loss in production systems.

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...
