Abstract
The invention provides a roll-back processing system for multi-mirror-image data. The roll-back processing system comprises a virtual processing unit, a state comparing unit and an instruction execution unit, wherein the virtual processing unit is used for executing virtual roll-back corresponding to data roll-back instructions when a mirror image managing server receives the data roll-back instructions, the state comparing unit is used for recording virtual roll-back states after the virtual roll-back and comparing the virtual roll-back states with mirror image service mark points corresponding to the data roll-back instructions, and the instruction execution unit is used for controlling the mirror image managing server to execute the data roll-back instructions under the circumstance that the virtual roll-back states are matched with the mirror image service mark points, and controlling the mirror image managing server not to execute the data roll-back instructions if not. The invention further provides a roll-back processing method for the multi-mirror-image data. According to the technical scheme, whether the roll-back instructions are executed correctly can be judged through the virtual roll-back, and therefore correct execution of data roll-back operation is ensured.
Description
Technical field
The present invention relates to technical field of data processing, in particular to a kind of rollback disposal system of many mirror image datas and a kind of rollback disposal route of many mirror image datas.
Background technology
In data handling procedure, often by preserve the Backup Data of a plurality of time points for data, thereby, when error in data occurring, can process by rollback the state while returning to the time point before certain, reduce loss.
Yet, while directly carrying out rolling back action, still mistake may appear, such as rollback process itself is made mistakes, or selected wrong rollback time point etc. all may cause the rollback mistake.
Therefore, need a kind of new rollback treatment technology, can judge whether correctly to have carried out the rollback instruction by virtual rollback, guarantee the correct execution of data rewind operation.
Summary of the invention
The present invention just is being based on the problems referred to above, has proposed a kind of new rollback treatment technology, can judge whether correctly to have carried out the rollback instruction by virtual rollback, guarantees the correct execution of data rewind operation.
In view of this, the present invention proposes a kind of rollback disposal system of many mirror image datas, comprising: Virtual Processing Unit, at the mirror image management server when receiving the data rewind instruction, carry out the virtual rollback corresponding to described data rewind instruction; The epidemic situation comparison unit, for recording the virtual rollback state after described virtual rollback, and compare with the data mode of mirror transaction gauge point corresponding to described data rewind instruction; Instruction execution unit, in the situation that described virtual rollback state and described mirror transaction gauge point are complementary, control described mirror image management server and carry out described data rewind instruction, otherwise do not carry out.
In this technical scheme, in advance the data that occur are each time merged and the operation such as fractionation, all generate corresponding data difference daily record, and the daily record point is set, the mirror transaction gauge point is the daily record point generated.Therefore, the mirror transaction gauge point, in fact corresponding to certain fixing data mode of having put down in writing in daily record, compares by the data mode by after virtual rollback and corresponding mirror transaction gauge point, thereby judges whether this virtual rolling back action is correctly carried out.By carrying out in advance virtual rolling back action, thereby, when mistake occurring, can again operate, cause the mistake that can't retrieve while avoiding direct rollback.
