Abstract
The invention relates to the field of computer data processing, a dependable backup function is achieved, by exploring data, and an initial base data version is formed and labeled according to time. When a server starts, an initial base data base point which contains a time label can be formed, and then modification is continuously carried out by normal data which are produced continuously on the data base point. When backup software detects that data variation and data base point variation are matched, the backup function can be carried out; otherwise, when the data variation is abnormal variation, the data base point is not changed, backup cannot be carried out by the backup software on wrong data, and the confidence level of the data is affected.
Description
Technical field
The present invention relates to a kind of based on believable redundancy technique, belong to Computer Data Security process field.
Background technology
In recent years, along with the continuous increase of data volume, people be in large data age.And data also seem more important in the life and work of people, so, for the safety problem of data, also become a current very important topic.For redundancy technique, also back up from the present complexity that simply backups to the most at the beginning.Technology of data copy in society now, has obtained well universal.
What is backup, and backup is exactly for dealing with the fortuitous event that file, loss of data or damage etc. may occur, by the data Replica in robot calculator memory device in the mass-memory units such as tape.
Backup can be divided into system backup and data backup.
1, system backup: refer to operating system of user because of disk crash or damage, the system file that the reasons such as computer virus or artificial deletion by mistake cause is lost, thus cause computer operating system can not normal boot, therefore system backup is used, operating system is stored up in advance, supports for the standby after fault.
2, data backup: refer to user and data are comprised file, database, application program etc. are stored up, uses for during date restoring.
The effect of backup supports for standby, and substitute uses.
Backup is the basis of disaster tolerance, refers to as anti-locking system occurs that misoperation or the system failure cause loss of data, and all or part of data acquisition is copied to the process of other storage medium from the hard disk of applied host machine or array.Traditional data backup mainly adopts internal or external magnetic tape station to carry out cold standby.But this mode can only prevent the man-made faults such as misoperation, and its release time is also very long.Along with the development of technology, the magnanimity of data increases, and many enterprises start to adopt network backup.Network backup is generally realized in conjunction with corresponding hardware and memory device by the data storage management software of specialty.
More common backup mode has:
Regular tape backup data.
Remote tape storehouse, CD server backup.Remote key data+tape backup.Teledata library backup.Network data mirror image.Remote Switched Port Analyzer disk.
Redundancy technique comprises following several:
Resumption of system disaster (IDR=Intelligent Disaster Recovery).
Resumption of system disaster, is exactly when collapse appears in system, by considerably less step, by system reconstructing, can comprises system mend above, application software and data.The accuracy of recovery can be improved like this, shorten release time, shorten service outage duration.
Remote data copies
Data are produced in real time a available copy in other place, the use of this copy does not need to do date restoring, copy can be come into operation immediately.The largest benefit of data Replica is that copy data can be used immediately, and do not have data restore time, RTO is very good, and simultaneously because be copy in real time, RPO is also very good, obliterated data hardly.
Data Protection Technologies
CDP(Continuous Data Protection)
CDP technology is Data Protection Technologies the most popular at present, and it can capture all file-level or other data of block level write change, can carry out the recovery of the granularity of refinement more, can return to random time point to backup object.
Summary of the invention
The object of the invention is to realize believable backup functionality, by " prospecting " to data, forming an initial base data version, and according to the time, it being marked.
When the server starts, just can form one containing free target primary data basic point, the normal data then constantly produced constantly can be revised data basic point.
When backup software detect data movement and data basic point change match time, just can carry out backup functionality;
Otherwise when data movement is improper variation, data basic point does not change, and backup software just can not back up misdata, has influence on the confidence level of data.
Thus realize the trusted backup function of data.
Technical scheme of the present invention so realizes, and based on believable redundancy technique, described method comprises the steps:
During startup of server, form a primary data basic point.
Data generation normal variation, data basic point forms data basic point new accordingly on the basis of primary data basic point.
Backup software for the situation of data movement, detects that data movement and data basic point change when matching, just can carry out backup functionality compared with data basic point.
The improper variation of data, data basic point can not change, and is the data basic point that previous moment is formed.
Backup software for the situation of data movement, detects that data basic point does not produce corresponding variation, just can not carry out row backup tasks compared with data basic point.
Accompanying drawing explanation
Fig. 1 is data basic point variation schematic diagram;
Fig. 2 is believable backup schematic diagram.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, in conjunction with once accompanying drawing, the present invention is further elaborated.Should be appreciated that concrete enforcement described herein is only in order to explain the present invention, is not intended to limit the present invention.
The object of the invention is to realize believable backup functionality, by the situation of change of data compared with the situation of data basic point, the data of coupling are backed up, realize the carrying out safety backup of data, improve the confidence level of data.
Described method comprises the steps:
During startup of server, form a primary data basic point.
Data generation normal variation, data basic point forms data basic point new accordingly on the basis of primary data basic point.
Backup software for the situation of data movement, detects that data movement and data basic point change when matching, just can carry out backup functionality compared with data basic point.
The improper variation of data, data basic point can not change, and is the data basic point that previous moment is formed.
Backup software for the situation of data movement, detects that data basic point does not produce corresponding variation, just can not carry out row backup tasks compared with data basic point.
As Fig. 1, startup of server during 9 o'clock sharp, forms a primary data basic point, 9: 5 timesharing, data change, and whether detect is normal variation, if normal data variation, just can generate the data basic point of 9: 5.Can not generate on the contrary, appointing is so the data basic point of 9 o'clock sharps.
As Fig. 2,9: 5 timesharing, data movement, carrying out backup operation, when detecting that time origin conforms to data variation, backing up.Do not back up on the contrary.
