Embodiment
Below in conjunction with accompanying drawing, specify the present invention.
Can recover after losing in order to ensure critical data, local backup recovery policy and the remote backup recovery policy that is connected by network are provided in the computer system of the present invention simultaneously.As shown in Figure 1, it is for realizing the theory structure synoptic diagram of the computer system of the present invention that data are recovered.It comprises local data, local backup and some remote backups.Local data and local backup are positioned at same place, can be positioned between them on the same station server, also can be by private line access.Local data and remote backup are positioned at the strange land, link to each other by network between them, when the transmission of data takes place, can be automatically to data encrypt, transmission security, data integrity checking such as consistency checking.It is hiding invisible that local backup and remote backup all can be elected bottom as, and wherein remote backup also can be used as to use and uses.
As shown in Figure 2, it is a process flow diagram of the present invention.It comprises: the method that the method for data backup before breaking down and the data afterwards that break down are recovered.
(1) method of data backup
S1: safeguard a backup file tabulation that dynamically updates, principal computer is made daily record according to this backup file tabulation with the file in the backup list and associated system parameter message and is kept at least one the backup computer;
S2: when the file in the backup file tabulation takes place to change, back up its increment information and associated system parameter message, and draw difference information by increment information and original backup;
S3: the user selects that crucial Backup Data is carried out bottom and hides, to reach data storage safety;
S4: long-range when the network backup, data are carried out cryptographic operation to reach data transmission security;
S5: after transmission is finished data are carried out consistency checking to guarantee data integrity and consistance;
(2) method of data recovery
S6: the recovery setting of obtaining the user;
S7: judge whether system can begin to carry out data and recover;
S8: carry out data and recover, the difference information that is generated by incremental backup generates required difference backup, by backup and the synthetic required backup of difference backup fully first, returns under the respective paths.
Below specifically introduce each step.
One, step S1
Safeguard a backup file tabulation that dynamically updates.It is such that what is called dynamically updates: to the unique top of file of each file allocation in the backup file tabulation, what be shown to the user is routine informations such as filename, file attribute, file size, date created.When the user dynamically increases backup file,, its filename is increased in the backup file tabulation newly-increased file allocation top of file.Deleted certain file in local data, and this file is in backup file tabulation the time, the user is provided following option: 1, mistake deletion, recovery file is to assigned address.2, keep backup file.3, deletion backup file, and from listed files, leave out this.In local data, certain file has been carried out the rename operation, and this file with corresponding document rename in the backup file tabulation, and keeps its raw filename information in backup file tabulation the time.
Regularly, be kept at least one the backup computer the renewal that backups of backup file tabulation, Backup Data (be chosen as local backup or remote backup or both) situation, relevant system parameters information.
Two, step S2
Regularly the file in the backup file tabulation is checked item by item, whether the respective file of checking in the local data that is assigned top of file has change, carry out the backup of increment difference as if the data and the system parameter message of this moment that have change to its change, then do not skip if there is change.If checking out All Files does not all have change and then generates corresponding journal file and write down this situation.
The availability of check data not only when one of important feature of the present invention just is restore data has also been checked the consistance of pertinent system information.Can improve greatly like this that data are successfully recovered, correct available possibility.The correlation parameter information that these need write down is as shown in the table:
| The correlation parameter information that needs record |
| Drive |
| Current system state |
| File path information |
| Top of file |
| File attribute |
| File size |
| File user authority information |
Adopt increase difference backup mode to solve volume of transmitted data and data keeping within bounds mutually between release time greatly, reach very short data requirement release time relatively with minimum volume of transmitted data.
Three, step S3
The user selects that crucial Backup Data is carried out bottom and hides, and this is in order to reach higher data storage security consideration, also to have been avoided virus, trojan horse program or hacker's infringement from another angle, like this from having guaranteed that to a great extent critical data is not leaked.
The bottom concealing technology that the present invention adopts can be realized thoroughly hiding of data.
Four, step S4
Long-range when the network backup, data are carried out cryptographic operation to reach data transmission security.The encrypted transmission sixty-four dollar question is the privacy of key.
The key rotation maker that the present invention utilizes the network two ends to install simultaneously makes key needn't pass through Network Transmission, has therefore well solved this problem.
Five, step S5
After transmission is finished data are carried out consistency checking to guarantee data integrity and consistance.Because can being chosen in, the user whether data are decrypted after transmission is finished, or non-decrypting direct preservation, so consistency checking also has different processing policies at different situations.
If what the user selected is that next step operation was carried out in deciphering again after transmission was finished, then consistency checking can be before file data encrypt to take place to its generate consistency desired result and, as shown in Figure 3, if what the user selected is non-decrypting after transmission is finished, then consistency checking can be after file data be encrypted to its generate consistency desired result with, as shown in Figure 4.
Six, step S6
Can detect or manually start data automatically by system recovers.
When needs carried out the data recovery, the recovery setting that at first should obtain the user, the recovery before this just comprises were set and how to be used these to recover setting afterwards.
Step S6 can be by following substep specific implementation:
(1) obtains the relevant setting of backup file, comprise backup policy, backup place (local, long-range), backup file tabulation information such as (comprising path, parameter information);
(2) potentially conflicting of detected parameters option in the parameter setting up procedure generates " data recovery parameter " option list;
(3) set all correlation parameters that recover about data, position (the acquiescence: this locality) that comprises backup file, release time, point (was given tacit consent to: the last recoverable time point), recovery file item (acquiescence: the last recoverable all files is treated in selection, the operation of carrying out comprises: the selected file/file that will recover from the file of all demonstrations and Folder List, or use the selected file type that will recover of asterisk wildcard (*)), the position of recovery file (acquiescence: the path during backup), whether carry out non-accurate recovery (if backup file goes wrong);
(4) generate correct, available " data are recovered parameter configuration files (DRPF) ", and be kept at fixing position.
Seven, step S7
Recover boot by one and judge whether system can begin data and recover, and sees also Fig. 6.
Step S7 can be by following substep specific implementation:
(1) receive the data recovery request, the relevant setting, the reading of data that obtain backup file are recovered parameter configuration files (DRPF);
(2) be defined as local recovery or remote recovery: remote recovery then carries out step (3), and local recovery then skips steps (3) directly carries out step (4);
(3) data are recovered software transmission and arrived far-end so that operation afterwards; Call encrypting module with this software cryptography; This software transmission after calling transport module and will encrypting is to far-end; Far-end is with this software decryption (optional); The far-end service data is recovered software, keeps two ends communication;
(4) check the two ends file system type: file system is identical, then directly carries out step (5), and file system is inequality, and then data recovery software change bak makes and waits that the file system of recovering machine can be identified, and carries out step (5) again;
(5) backup file of recovery file and integrality, the availability of daily record are treated in inspection: judge that backup file and daily record are imperfect, then carry out step (6), but the complete time spent is then carried out step (7);
(6) data are recovered software and are reported an error, and information that will " information deficiency can't restore data " is shown to the user, and provides the date and the state that can return to select for the user, gets back to step (5);
(7) check whether current systematic parameter is consistent with the required relevant system parameters of recovery file: inconsistent, then carry out step (8), unanimity is then carried out step (9);
(8) eject dialog box, select whether to change the far-end setting, get back to step (7) by recovering requirement by the user;
(9) log-on data is recovered.
Eight, step S8
The execution data are recovered, and the difference information that is generated by incremental backup generates required difference backup, by backup and the synthetic required backup of difference backup fully first, return under the respective paths.
Step S8 can be by step specific implementation quickly:
(1) receives the log-on data recovering information, determine the integrality of backup file, differential file and journal file that recovery is required;
(2) call the interface of hiding module corresponding document is shown, show failure, then carry out step (3), show successfully, then carry out step (4);
(3) retry if the retry failure then reports an error, is got back to step (2), and step (4) is then carried out in the retry success;
(4) with backup file and the synthetic a backup file fully of differential file;
(5) check recovery setting, corresponding document is recovered in the chkdsk space by path, and disk space is not enough or do not have respective paths, then carries out step (6), and disk space is enough and find respective paths, then carries out step (7);
When (6) recovering corresponding document by path, do not use for recovery file if find corresponding path then Make Path, also to check whether this place, path has enough disk spaces this moment, if disk space inadequately then eject dialog box and allow the user select to change path or release disk space, check once more, if disk space enough then carry out step (7);
(7) call the integrality of data consistency checking module verification file, then do not carry out step (8), then carry out step (9) by data consistency checking by data consistency checking;
(8) not by data consistency checking, think that then two end datas are inconsistent, report an error and select to ignore or retransmit corresponding document, get back to step (7) for the user;
(9) finish the recovery and checking of All Files after, generate Log Report.
