Description
Technical field
The invention belongs to Data Protection Technologies fields, more specifically more particularly to a kind of continuous data store method.
Background technique
With computer technology, the development of multimedia technology and network technology and IT application in enterprises degree are higher and higher,
Demand of the people to data is in explosive growth, makes data storage protection technology that revolutionary variation occur.This variation master
Show that three aspects are the extension for sharply expanding the followed by data ready time of memory capacity first, data must assure that
Daily 24 hours, seven days a week, 365 days every year be in ready state；Finally, the structure of data storage is different.
In the epoch of globalization e-commerce, data should be towards global, and the access of data should only be pacified
The management of full mechanism, without should be by the constraint of regional space.And for an enterprise, the safety of data is extremely
Important, once important data are destroyed or lose, great influence will be caused to the daily production of enterprise, be even difficult to
The loss made up.According to the latest survey of company, for enterprise, restores data and at least need a couple of days, and consume a large amount of
Fund.It is to be in state of paralysis on entire enterprise practical and in recovery process.In today, up to the paralysis foot of a couple of days
To cause any a company to go bankrupt.In order to reduce because data corruption and caused by massive losses, many data backup memories
Technology and storage management technique come into being, and the end host of data backup memory technology and storage management derived from the age calculates mould
Formula, at that time since data concentrate on host, manageable mass memory unit --- tape library is indispensable at that time sets
It is standby.It is universal due to the most widely used client server mode of the development of PC, especially the nineties after the eighties, this
When network on file server and database server be often place in the data set of key, and one is also accumulated from client
Quantitative data, the distribution of data cause the complication of data storage management.
Analysis data the reason of being destroyed, mainly there is the following aspects: 1, natural calamity, as floods, fire, lightning stroke,
Earthquake etc. causes the destruction of computer system, and storing data is caused to be destroyed or lose completely；2, system manager and maintenance people
The maloperation of member；3, computer equipment failure, data caused by infecting including the aging of storage medium, defective virus are broken
It is bad；4, how the intrusion of " hacker " and sabotaging from intranet, reduce the loss of data at the same time, just at needing
One of solve the problems, such as.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of continuous data preservation side proposed
Method.
To achieve the above object, the invention provides the following technical scheme: a kind of continuous data store method, specifically include as
Lower step:
S1: CDP data protection APP program is installed in user client；
S2: after installing CDP data protection APP program, client landing program, CDP data protection APP program is automatically right
Host to be protected is needed to do a data scanning synchronous with data；
S3: by the monitoring module built in CDP data protection APP program, monitoring module detects that file generates in host
When variation, find the change location of data, and differential data is transmitted on server, monitoring module can with continuous acquisition or
Data variation is tracked, and generates IO log space, by the independent storage of the IO log space of generation to its outside main storage space
In his memory space；
It realizes that the fine granularity of IO rank is backed up in realtime in S4:S3, and generates the disaster tolerance data independently of creation data,
And can be realized the data rewind of historical time point, service take-over can be both carried out, also can solve mathematical logic mistake；
S5: showing by way of by disaster tolerance data carry, and the data of carry are readable writeable, and user can basis
Actual scene carries out the data carry of any point-in-time, restores oneself desired historical data.
Preferably, other memory spaces outside the main storage space include disk and CD.
Preferably, stickup position sensor and RFID label tag are fixed on the disk and CD.
Preferably, the monitoring module includes timing detection module and file operation detection module.
Preferably, the timing detection module protects instance data situation of change for periodically detecting, when data produce
When changing, IO log is generated in time, and save to IO daily record data.
Preferably, the file operation detection module is used to monitor the operation of file, starts when file is modified new
Version generates task, generates the latest edition of host data in time.
Preferably, the disaster tolerance data support the rehearsal of Redundancy Machine any point-in-time, can verify the number of current point in time
According to whether correctly, whether can carry out disaster-containing pipe.
Preferably, the IO daily record data storage uses the LAN-FREE network architecture.
Technical effect and advantage of the invention: a kind of continuous data store method of the present invention, real-time monitoring produce business fortune
Row state, if chance failure occurs, system can carry out service take-over in first time, ensure production business continuous service；This
External system utilizes disk level CDP technology, realizes that the fine granularity of IO rank is backed up in realtime, can be real according to business scenario needs
The data of existing history any point-in-time restore and business rehearsal, can effectively be directed to virus attack, artificially accidentally the data such as affected are patrolled
Mistake is collected, ensures that data are authentic and valid in all directions, and the business of any point-in-time is supported to drill, is not influencing production business fortune
In the case where row, a set of and duplicate simulated environment of production business can be simulated, for verifying the complete of historical data
Property.
