Abstract
A kind of technology based on CDP continuous data protections refers to uninterrupted monitor data automatically; continuous capture and Backup Data change; the fast quick-recovery of data can be carried out by any operation step number or time point; for the data of structured database type; it may return to any state of database; for non-structured data, the time point specified may return to.So as to give the data delete or damage by mistake before for change.The complete type of data is not only ensure that during recovery, and can guarantee that the integrality of event.
Description
Technical field
The present invention relates to a kind of technology based on CDP continuous data protections, belong to computer disaster-tolerant backup field.
Background technology
In the beginning of new century, the mankind are just coming into the era of knowledge-driven economy using information technology as core, and information resources have turned into
The strategic resource of equal importance with material and the energy, countries in the world all assign quickening informatization as national development strategy.
Along with the continuous propulsion of informatization, operation system is constantly expanded, and the data volume and day that operating information system is produced are all
Increase, importance is also gradually stepped up, for the crucial application of some users, any amount of loss of data all may result in
Huge loss.
The risk of operation system loss of data：
Logic error：Probability of happening is very high, and artificial maloperation is deleted, virus, the factor such as staging error, is likely to lead
Cause the loss of data.
Server hardware failure：Probability of happening is higher, loss of data caused by the hardware fault such as hard disk, internal memory, power supply.
Storage media failure：Probability of happening is high, and concrete reason has, and RAID card is damaged, RAID card battery electric power exhausts, notch
Loss of data caused by control chip damage etc..
If can not be adopted an effective measure to risk, once data are lost due to certain above-mentioned reason, it is possible to cause
When extreme loss, especially core data are lost, it is entirely possible to cause the paralysis of whole operation system.Data backup is disaster tolerance
Basis, refers to operational error occur for anti-locking system or the system failure causes loss of data, and by all or part of data acquisition system
The process of other storage mediums is copied to from the hard disk or array of applied host machine.
Conventional backup means inefficiency, after failure, recovers very long cumbersome, operability is very low.Typical user
Backup flow is such：An incremental backup will be carried out in morning daily, full backup is then carried out per morning at weekend.Using
This method, once occurring in that data disaster, user can return to the data in certain day (attention is in units of day), therefore
In the worst case, the data of whole one day may be lost.
Therefore, in order to ensure the greater security of data, user must carry out on-line system online duplication in real time, to the greatest extent may be used
The high availability of data can be maintained using disk management technologies such as snapshots more.CDP technologies are uninterrupted data to be entered
The automatic monitoring of row, continuous capture and Backup Data change, can carry out the fast quick-recovery of data by any operation step number or time point, right
In the data of structured database type, any state of database is may return to, for non-structured data, be may return to
The time point specified.So as to give the data delete or damage by mistake before for change.Data are not only ensure that during recovery
Complete type, and can guarantee that the integrality of event.
CDP system can provide three kinds of backup modes based on application layer, file-level and block level, and recover the nothing of target
Any variable recovery point of limit.
1st, the CDP based on application system realization takes larger just for protected application system to application system resource.
2nd, the CDP based on file system realization writes FAT table by monitoring the data variation on file system aspect
Afterwards, just start to replicate, while needing first to read data, consume a large amount of system resources, increase the consumption of the network bandwidth.
3rd, the CDP based on block level, continues to write delta data, middle section to target device after initialization disk synchronization
CDP data protection systems in the same direction have also combined file-level CDP advantage, and file system parsing is added in web management interface
Function, the data block that can be taken by file system on a timing disk, be greatly saved initial synchronisation needs time and
The space that Backup Data takes.
Subregion is encrypted under an operating system for user, middle section be able to will own using CDP disk mirrorings in the same direction
Partition data include state completely copy come, when need access Backup Data when, it is not necessary to excessive adjustment, this is also base
In block level CDP exclusive advantage, the protection based on file and application daily record can not be realized.
The content of the invention
The present invention seeks on the premise of not influenceing operation system to run, it is possible to achieve lasting to catch or tracking number of targets
According to any change occurred, when hardware and software failure occurs in operation system, and random time point before this can be returned to
Method, is ensured using the technology based on continuous data protection.
In order to reach the purpose of operational sustainability, the technical proposal of the invention is realized in this way：
The technology is different from the snapshot of conventional store, and using passive type mechanism, the action of perception data banked cache brush is simultaneously
It is marked on I/O records, and in advance by file data changing unit together with current system timestamp (System Time
Stamp) together automated back-up to middle section CDP memory banks in the same direction.
CDP technologies are uninterrupted monitoring and the change of Backup Data server data, can be returned to over any
At time point, it is really to back up in realtime, does not result in the loss of data.Such as Fig. 1
Its method and step is as follows：
First：Client is installed on protection server, using passive type mechanism, the action of perception data banked cache brush
And be marked on I/O records.
Secondly：On the premise of not influenceing main business to run, it is possible to achieve lasting seizure or tracking target data is sent out
Raw any change, CDP memory banks are backuped to by data increment.
Finally：When hardware and software failure occurs in operation system, the data of random time point before this can be recovered, do not resulted in
The loss of data.

Embodiment
In order that the purpose of the present invention, technical scheme and feasibility are more clearly understood, with reference to accompanying drawing, to present invention progress
It is further to describe in detail.It should be appreciated that specific embodiment described herein is only to explain the present invention, and without
It is of the invention in limiting.
The present invention proposes a kind of method based on continuous data protection, it is ensured that data safety and reliability.
Methods described comprises the steps：
First：Client is installed on protection server, using passive type mechanism, the action of perception data banked cache brush
And be marked on I/O records.
Secondly：On the premise of not influenceing main business to run, it is possible to achieve lasting seizure or tracking target data is sent out
Raw any change, CDP memory banks are backuped to by data increment.
Finally：When hardware and software failure occurs in operation system, the data of random time point before this can be recovered, do not resulted in
The loss of data.
