Description of drawings
Fig. 1 is the method flow diagram that the present invention carries out system backup;
Fig. 2 is that the present invention carries out the method flow diagram that system is recovered.
Embodiment
Introduce in detail a typical embodiment below in conjunction with accompanying drawing.
In order to use technical scheme proposed by the invention, at first be disk of lottery ticket sales terminal configuration, this disk can be the DOM dish, also can be the high rotating speed hard disk of IDE.This disk is divided into two districts: workspace and backup area.Wherein, shared space, workspace approximately is 70% of whole disk space, and backup area accounts for about 30%.The lottery sale system that uses when normal ticketing is stored in the workspace comprises operating system and the lottery ticket sales program that is installed on this operating system.And backup area is used for system that simplifies the operation (for example MiniRoot system) that only has Shell of storage, and this system of simplifying the operation can carry out the solution press operation of compressed package, and backup area also is used for the storage backup file in addition.According to the reality measuring and calculating, minimized Iinux operating system probably accounts for the space about 15M, and the backup file after the existing lottery sale system compression is probably had 80-100M, and therefore whole disk space should be greater than 512M.
When lottery sale system is backed up, need first the data in the main partition to be compressed, can carry out compression and decompression with bzip2 or gzip instrument.Wherein, bzip2 can obtain higher ratio of compression, but its shortcoming time that to be compression and decompression spent is long, that is, the time of backup-and-restore is long.Also can adopt the gzip instrument to carry out compression and decompression, although ratio of compression can hang down, the backup-and-restore process is consuming time obviously will lack.Following table 1 shows and adopts bzip2 and gzip instrument to compress time with decompress(ion).
| Compare item | bzip2 | gzip |
| Decrement | 60M | 63M |
| Compression time | 25 seconds | 13 seconds |
| Decompression time | 20 seconds | 5 seconds |
Table 1
If disk space is not very narrow, consider that from the efficiency comes first angle suggestion adopts the gzip instrument to carry out compression and decompression.
In addition, the spent time length of backup-and-restore is also relevant with the performance of disk itself with terminal.Following table 2 showed when the terminal type that adopts different performance, the used time of MiniOS system of a 166M of backup-and-restore.
Table 2
Wherein, the performance of LA800W type is better than La600A, and as seen, the speed of the terminal backup-and-restore that performance is good obviously is better than the general terminal of performance.In addition, when practical application was backed up, compression time may be slightly longer than the time that upper table is put down in writing, and the estimation of LA600A type is the longest can not to surpass 15 seconds, that is, monolithic backup was finished within 2 minutes.And the good type BACKUP TIME of other performance is probably at 50-120 between second.
Namely can begin on the basis of the above the work backing up and recover, at first will current lottery sale system be backed up, mainly comprise the steps (referring to Fig. 1):
101, the user carries out shutdown, activates backup.When the user carries out shutdown command, init shutdown process can be dispatched the halt service, and the present invention right/etc/rc.d/init.d/halt service revises, increased at the halt server/fill order of sbin/bakafter, therefore, before disk is closed in the halt execution, can continue to carry out following backup process.And why select this time point, and be because system program been has no longer has been read and write disk, back up safer this moment.
102, derive disk space.Can calculate the total volume of disk in this step, the purpose of calculating disk size is to judge that this disk has and do not have enough spaces to be used for standby system.If there are not enough spaces to come standby system, then can to user's alarm, then jump out backup procedure and carry out the normal shutdown flow process.Because our disk space of selection is enough to hold standby system usually, the continuity that therefore shows for flow process, this accidental situation of not shown insufficient space in Fig. 1 of the present invention, but carry out according to the flow process of normal condition.In the other parts and Fig. 2 of Fig. 1, based on same consideration also not shown various accidental situation, but the record by this instructions word segment, for the accidental situation that may occur, those skilled in the art should understand and correctly process.
103, derive configuration.Derive configuration and from configuration file, read exactly parameter.These parameters comprise: whether catalogue, the backup functionality that the backup subregion hangs over root file system allow operation, backup failure number of times, back up how long once need, expired times etc.
104, the cleaning garbage files.Garbage files mainly refers to the journal file of the temporary file that produces in system's installation, the program operation process, the installation kit that does not re-use, system's operation etc.
105, open backup area, and check the backup condition.
The backup condition is judged from the configuration of deriving, is mainly comprised:
1) whether backup functionality allows operation;
At configuration file a configuration item is arranged, if configuration item is true, during shutdown, can start backup; Otherwise, just do not back up.If closed backup functionality in the configuration file, then can and jump out backup procedure to user's alarm this moment, carry out the normal shutdown flow process.
2) backup failure number of times.
If backup failed 3 times continuously then can and be jumped out backup procedure to user's alarm equally, carry out the normal shutdown flow process.If this situation occurs, illustrate that terminal has unusually, backup has not had purposes.
106, removing does not need the block device that backs up.
Block device generally is memory device, disk unit etc., and these equipment represent first subregion of first disk such as/dev/hda1 generally under/dev/ catalogue.Because backup itself is exactly the backup that disk file is carried out, so, during backup, these block files be ignored, otherwise backup failure can be caused.Do not need the block device that backs up, comprising :/dev/hda1 ,/dev/hdc1 ,/dev/loop1 ,/dev/ram1 etc.
107, the data of workspace are backuped to backup area.Namely use gzip that the data of workspace are compressed, and the file after will compressing is kept at backup area, simultaneously the workspace checked, and guidance information is set.After backup is finished, backup result is calculated a MD5 value, and be stored in backup area.
108, the deletion disk of safety.The elder generation timing disk, with data cached write disk after, delete again disk.If by force deletion, possible some data also at the buffer zone of disk, can cause the disk file mistake.
109, enter the normal shutdown flow process.
So just finished the backup of system, because backup needs the time (generally need 30-60 second), some user may not want to back up, and that user can change the configuration item in the configuration file into false.Like this, the process of above-mentioned backup will can not be performed in shutdown.
After lottery sale system is backed up, if run into the situations such as system crash or disk error so that lottery sale system can't normal boot, then can adopt following steps that (referring to Fig. 2) recovered in system:
201, start, user selection recovers standby system.The invention provides one herein and carry out the Grub interface that system is selected, requiring user selection is normally to enter master operating system or recover standby system, if user selection recovers standby system, and the flow process below then continuing to carry out.
202, system's guiding enters the system that simplifies the operation.This system storage that simplifies the operation can be that this system can carry out the solution press operation of compressed package such as the miniature Iinux such as MiniRoot system at backup area.
203, check service condition, such as user, disk space etc.Check the user just to refer to whether the active user is the power user, if not the power user or there is not superuser right, do not allow to continue this and recover flow process, jump out, and close current operation system; Whether the chkdsk gross space greater than predetermined value, for example 512M.If less than predetermined value, illustrate that disk does not possess the recovery condition, jump out, and close current operation system.
204, check the backup integrality.The MD5 value of the source file of generation checks the integrality of backup after finishing according to backup.As not mating, then can't recover, jump out and close current operation system.
205, the format workspace.
206, open the workspace.
207, the reduction standby system.With gzip the compressed file solution of backup area is depressed into the workspace.
208, the restorer node.Under linux system, some device node is the device node of sports lottery ticket special use, such as USBKey equipment.When these device nodes recover in system, need to recover in the lump.Because system does not back up/ device node under the dev/, so, when recovering in system, need the device node of special recovery sports lottery ticket special use.
209, close current operation system.
So far, if normal words, the sports lottery ticket marketing system is successfully recovered.The user starts shooting again, selects normally to enter the sports lottery ticket marketing system after master operating system can enter into recovery.
