Abstract
The invention provides a random time point backspacing technology aiming at achieving the backspacing of a random time point of data. When any changes happen to production center data, back-up is conducted on the data to form a journal. When problems or accidents occur, system software can be protected through continuous data of the technology, and by the utilization of the random time point backspacing technology of the data, the data can be more exquisitely and quickly recovered to a random moment before backups.
Description
Technical field
The present invention relates to the back off technique of a kind of random time point, belong to Computer Data Security process field.
Background technology
Under current large data age, the continuous increase of data volume, has brought new problem already.How data can better be ensured, even if there is beyond thought disaster, data remain safe, remain operable.Certainly; people are to this kind of problem now, propose solution, namely backup and recovery; but there is unsatisfactory place; such as backup policy is backup every afternoon 6, once go wrong before 5 o'clock cause loss of data, wants the data recovering the same day just to difficult for very much; for this kind of phenomenon; we have developed the back off technique of a kind of random time point, and have been applied in continuous data protection system software, can better address this problem like this.
There is the technology of a lot of time point rollback or recovery now on the market, as fixed time point back off technique.As the term suggests time point specifies, that is exactly regular time point, since be regular time point, certainly long time interval is just there is between those adjacent two time points, exactly because there is the existence of this time interval, if will return back between two time points, it also can only return back to one in these two time points, such rollback must cause the loss of partial data, and the data consistency of Backoff time point also cannot ensure.Fix time thus a back off technique relative to random time point back off technique maximum drawback be exactly that rollback point is limited, rollback point data consistency can not ensure.
And the rollback point time can freely fill in as required, the words of not free some restriction are exactly the back off technique of our said random time point.
One of continuous data protection system software is powerful is back up in realtime efficiently; and the powerful functional characteristics of another one is exactly random time point rollback; random time point rollback key point does not lie in rollback; and be random time point; in the time range that backup history allows; any one time point that can specify all can rollback, and the database ensureing rollback point is complete available, ensures the consistance of data completely simultaneously.By random time point rollback, the data that user misses deletion, maloperation can be given for change, when database occurs inconsistent, also easily can be solved by random time point rollback.It is by catching data variation and being stored on local hard drive, to realize recovering faster than backup tape.Can catch constantly and store data variation.
Summary of the invention
The present invention seeks to the back off technique of the random time point in order to realize data.Go wrong when production center data or suffer accident, by our continuous data protection system software, the back off technique of the random time point of data can being utilized, return to any time before backup fast by more meticulous for data.
Technical scheme of the present invention so realizes, and the back off technique of the random time point of data, described method comprises the steps:
Available data is carried out a full backup, in this, as the primary data of the production center.
Be according to recording a primary data with timestamp in the backup directory of main control end.
The data variation of the monitoring production center.
When finding that there is new data write, just capture data message immediately.
Be recorded in journal file with the form of timestamp equally.
More than to go wrong the early-stage preparations that the rollback that can obtain random time point does for data.
Transfer the journal file in required moment when data go wrong.
Search the rollback list of timestamp, carry out the date restoring on corresponding time point.

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 the back off technique of the random time point in order to realize data, by the detection to data, in real time crawl, file, when data go wrong, date restoring can be wanted to any one on the time point of recovery, quick, appropriate has ensured the security availability of data.
Described method comprises the steps:
Available data is carried out a full backup, in this, as the primary data of the production center.
Be according to recording a primary data with timestamp in the backup directory of main control end.
The data variation of the monitoring production center.
When finding that there is new data write, just capture data message immediately.
Be recorded in journal file with the form of timestamp equally.
Transfer the journal file in required moment when data go wrong.
Search the rollback list of timestamp, carry out the date restoring on corresponding time point.
As Fig. 1, first the data initial state of nine o'clock sharps of data is backuped, after the data variation of nine o'clock 03 and nine: 10 done a real-time backup, record with the form of timestamp, be stored in daily record.
As Fig. 2, after command recognition, according to the time of required rollback, find rollback list from daily record after, carry out the recovery of data.Thus realize the Backward Function of the random time point of data.
Claims (3)
1. the back off technique of the random time point of data, described method comprises the steps:
Available data is carried out a full backup, in this, as the primary data of the production center.
