Description
(1) technical field
What the present invention relates to is a kind of educational resource grade redundancy technique of IT application in education sector system.
(2) background technology
University Educational Administration place is the important management organization of tissue teaching, and educational archives is every material that Educational Affairs Office forms in teaching management process.Along with the development of educational undertaking and going deep into of University Education reform, the educational archives material forming in teaching management process is more and more, content is got over abundant, use gets over frequently, extensively, educational archives management work has become the important component part of Educational Affairs Office work, the quality of educational archives management work, will directly have influence on the performance of Educational Affairs Office function and the realization of teaching expection management objectives, even has influence on quality of instruction and the reputation of school.
Present educational archives is stored in the educational administration management system of each colleges and universities this locality mainly with the form of electronic record.Once generation disaster, education administration system just cannot normally be used.For guaranteeing the security of educational archives, should on the basis of original education administration system, set up standby system, by E-educational Administration archives copying in standby system in real time or regularly, with the information loss that loss of data was brought that reduces or avoid causing due to all kinds of disasters.This patent is used third party cloud as standby system, when there is disaster, can by the system of backuping each other, realize the recovery of data, can avoid the loss of data.In addition, educational administration's resource is incorporated on third party cloud stores, and does not need great amount of investment to buy hardware and software, saves to build and drops into.
The backup method of current information system mainly contains two kinds: back up in realtime and timed backup.When production system is carried out data storage, these data are backed up simultaneously.The benefit that employing is backed up in realtime is the consistance that can constantly keep production system and standby system data, completeness and the security of data are higher, its shortcoming is that the resource memory space of education administration system is larger, resource type is more, if adopt the mode of backing up in realtime, educational administration's resource that frequency of utilization is different can consume identical management cost, can cause the significant wastage of resource, loses more than gain.
Timed backup is that current application obtains the most a kind of data back up method.The method is exactly only data cover to be preserved when education administration system is stored, and only has when BACKUP TIME point arrives, and just nearest data is backed up.Adopting the advantage of the method is the resource that can make full use of system, backup tasks was assigned in specific free time, thereby can reduces system resource.Its shortcoming is if regularly strategy arranges improperly, for the higher educational administration's resource of frequency of utilization, likely loses from the Last Backup data message of storage later.
By upper surface analysis, the backup Main Bottleneck of education administration system is that the frequency of utilization of educational resource is uneven, use single backup mode can not make full use of system resource, therefore, according to the characteristic of all kinds of resources of education administration system, for its distinctive operating characteristic, take corresponding backup mode, improve the utilization factor of education administration system, optimization data backup efficiency.
(3) summary of the invention
The object of the present invention is to provide and a kind ofly can carry out according to educational administration's resource characteristic the method for data backup.The method by be stored in resource in educational administration management system according to its distinctive service time character adopt respectively in real time, regularly and manual mode transfer to backup protection in third party cloud; According to the distinctive educational administration of resource character, this method is divided into three backup grade Grade by resource: for the resource with term characteristic, within certain period, often there is to revise the resource of change in real time, distribute real-time grade Grade=T, for the resource with academic year characteristic, the resource of upgrading in the set time, distributes regularly grade Grade=A; For Archive Resource, not with or the less resource of change in time, distribute fixed-level Grade=P, with this, form the backup grade Grade={T of resource, A, P};
This method is implemented different backup mode Me according to the grade of resource, resource for Grade=T, back up in realtime (Me=backs up in realtime), once resource is stored in education administration system, just this resource transmission is backed up in third party cloud, latest edition as this resource, the old version of resource is not deleted, resource for Grade=A, carry out timed backup (Me=timed backup), setting this resource transmission to the third party cloud that regular time names a person for a particular job in education administration system backs up, the storage of other times is not backed up, resource for Grade=P, manually back up (Me=manually backs up), until carry out again this resource backup while receiving the manual backup request of resource, other storage resource requests do not back up,
