Description
Technical field
The present invention relates to the method that a kind of serial realizes many device data backups, belong to data communication technology field.
Background technology
Access server is after paying the user, and the user has carried out relevant configuration according to the service needed of oneself to these equipment, and these configurations are kept in the access server.Usually, for guaranteeing the correctness of configuration, these configurations all must be undertaken by the attendant, and also can carry out some modifications in user's use afterwards.Cause losing of configuration data for fear of going wrong when the Back Administration Module (Background AdministrationModule) of access server later on, just current database need be backed up, in order to using during the recovery configuring data future.And, will not carry out data backup for some statisticss that comprise in the database on the BAM, to reduce memory space and to reduce taking of Internet resources.
Existing data back up method is as follows:
In order to back up the configuration data on the BAM, adopted based on Simple Network Management Protocol (SimpleNetworkManagementProtocol, hereinafter to be referred as SNMP): provide related administrative information storehouse (ManagementInformationBase) for data backup specially, when needs carry out data backup, the application program of webmaster is to specifying BAM and appointed object sign (ObjectIDentifier, hereinafter to be referred as OID) issue the SNMP read operation, after SNMP agency on the BAM receives the SNMP read request and confirms as the OID of Backup Data, from database, read the table data that need preservation, and send response message for the webmaster application program; Subsequently, the webmaster application requests is set up the terminal document transmission and is connected, and by the terminal document delivery means, BAM reports network management workstation with data, thereby finishes backup operation.During recovery, data transmission direction gets final product conversely.
The shortcoming of above-mentioned configuration data automatic backup method based on SNMP is:
1) fail safe is relatively poor: present application realizes based on the SNMP front page mostly, and snmp protocol utilizes connectionless User Datagram Protoco (UDP) to transmit data, except that the SNMP third edition has the safety check, simple authentication and access control only are provided, destroyed by malicious attacker easily, for example intercepting message sends false information, directly device parameter is made amendment etc.
2) efficient is lower: at first, in the SNMP front page protocol Data Unit, as long as there is a variable to make mistakes, just think whole protocol Data Unit processing failure will cause the inconsistent of webmaster and proxy data like this, also reduced treatment effeciency simultaneously; Secondly, SNMP is not suitable for retrieving big data block, because SNMP does not support the data block of fixed structure is operated; At last, each variable in snmp protocol data cell can only corresponding OID operation, and when therefore traveling through a plurality of proxy database, chronic, efficient was lower when a plurality of equipment were backed up.
Summary of the invention
The objective of the invention is to propose the method that a kind of serial realizes many device data backups, overcome the poor stability of prior art, transmit the low shortcoming of data efficiency, with reach regularly, accurately, backup configuration data and reduce the purpose of the shared Internet resources of Backup Data reliably.
The serial that the present invention proposes realizes the method for many device data backups, comprises following each step:
1, from configuration file, reads configuration information;
2, at interval, from database, obtain the information of the Backend Administration Module (being called for short BAM) managed, set up the BAM formation, start one simultaneously and check BAM backup instances timer according to the setting of configuration file;
3, take out first BAM that does not back up in the above-mentioned formation, and create the backup operation task;
4, according to the information of above-mentioned BAM, login this BAM, carry out authentication, if checking is not passed through, make " backup failure " mark, change step (6), if checking is passed through, carry out next step;
5,, and carry out backup operation to execution backup operation task initialization;
6, by checking BAM backup instances timer, find out the next BAM creation task in the described formation, repeating step (3) (4) (5) is up to all BAM in the formation are disposed.
In the said method, BAM information comprises IP address, login username and the password of BAM.
In the said method, login authentication is undertaken by man-machine interaction verbal order (hereinafter to be referred as MML).
In the said method, also comprise the process of a monitoring BACKUP TIME, comprise the steps:
1, during initialization, creates supervision poll timer;
2, whether regular check arrives BACKUP TIME;
3, behind the arrival BACKUP TIME, create the backup operation task.
In the time of above-mentioned monitoring BACKUP TIME, also to check the process of the backup instances of BAM, may further comprise the steps:
When 1, arriving BACKUP TIME, supervision poll timer creation is checked the timer of BAM backup instances;
2, according to the time interval of setting, this timer is checked the backup instances of BAM in the formation;
3, after all BAM backups finish in the formation, delete this timer.
In the said method, after BAM logins successfully, check whether the disk remaining space of network management workstation is lower than the value of regulation, if, the backup file before then deleting.
Backup operation in the said method comprises the steps:
1, the network management workstation in configuration information is deposited under the catalogue of file, creates one with the IP address of this BAM and the catalogue of BACKUP TIME name;
2,, revise the above-mentioned relevant parameter in the MML backup command, and carry out the MML backup command according to network management workstation IP address and the backup file deposit position on network management workstation in the configuration information; 3, as if backup failure, then the backup instances with BAM is designated " backup failure ";
4, if back up successfully, then the backup instances to BAM is carried out record in database, comprises the IP address information of the corresponding directory name of record, BACKUP TIME, BAM.
The serial that the present invention goes out to propose realizes the method for many device data backups, order realizes data backup based on MML, backup efficient and fail safe have been improved, and can make backup tasks issue with the storage of Backup Data separately, the separation of duties that helps webmaster work, reasonable distribution network management workstation resource.The layering processing that utilizes monitor task and execute the task and realize the self-timing backup: monitor task is in the upper strata, handles regularly, judges whether to carry out backup operation according to certain criterion; Execute the task and only manage the enforcement of backup operation, function is well defined, the code efficiency height.Serialization of the present invention transmits data in time and expands, and utilizes the prolongation of time, has reduced taking Internet resources.The inventive method has adopted the automatic deletion of Backup Data, has reduced taking disk space.Therefore the advantage of the inventive method is: need import the occasion of data at all, all provide the correct scope of input data, make the user have only the choice, and can not optionally import data, so good reliability.Because data configuration all will influence the operation of equipment or user's online, therefore must carry out strict user rs authentication, and do relevant operation note, so fail safe is good.

Too short in order to prevent user configured polling time interval, supervision poll timer will be checked the backup instances sign of each BAM in the formation, if the backup instances of all BAM sign all is " backup finishes ", then create formation again; Otherwise, just do not rebuild formation, and directly start regularly next time.
Supervise the poll timer each blanking time and compare,, then do not do anything if do not arrive BACKUP TIME with the backup operation time (above-mentioned configuration item 5) of setting; If the time arrives, then from database, inquire about the BAM that network management workstation is managed, obtain IP address, login username and the password of BAM; For all BAM set up a formation, backup operation is subsequently carried out according to the order of each BAM in formation; Too short in order to prevent user configured polling time interval, supervision poll timer will be checked the backup instances sign of each BAM in the formation, if the backup instances of all BAM sign all is " backup finishes ", then create formation again; Otherwise, just do not rebuild formation, and directly start regularly next time.
Take out and not carry out first BAM of backup operation in the formation, carry out the MML order of login; If login is unsuccessful, then the backup instances of this BAM of mark is designated failure, so that later retry; If login successfully, then the chkdsk remaining space (with configuration item 2 relatively) and the backup operation number of times of data-base recording, see whether need to delete before the file of backup---can avoid like this causing the unrestricted growth that disk resource is taken because of back-up job; If the backup operation number of times surpasses set point, perhaps the disk remaining space is lower than the setting lower limit, then the file that produces of the backup number of times of the number (configuration item 3) set of deletion and the historical record of revising database; Otherwise, do not delete.
The task of backup operation is carried out in initialization, and carries out backup operation: whether the catalogue (configuration item 4 is set) that the inspection network management workstation is deposited file exists, and if there is no, just sets up this catalogue; Create a catalogue then, and set up catalogue (as backup 0: 0: 0 on the 22nd August in 2002, then catalogue by name 20020822000000) below, realize depositing in a organized way of Backup Data with the time name that is accurate to second with the IP address name of BAM; According to the network management workstation IP address of configuration item 6 and the backup path of configuration item 4, revise MML order (configuration item 8) the network management workstation IP address of Backup Data and the parameter of backup path, and carry out this MML order; The backup instances of revising this BAM is designated " backing up ".
After this order that is finished, check execution result, if success then the backup instances of revising BAM is designated " backup finishes ", and in the historical duplicated record table of database, add a record, write down the IP address information of corresponding directory name backup, BACKUP TIME, BAM, use when being used to delete backup file; Otherwise, revise backup instances and be designated " backup failure ".Subsequently, it is deleted to execute the task, and the recording operation daily record.
In the Timing Processing of supervision poll timer, also comprise and create the timer of checking the BAM backup instances: according to the time interval of setting (configuration item 9 is set), this timer is made regular check in the whether formation all BAM and is all backed up and finish, and taking out not have the BAM of execution to back up; If all BAM have backed up, reexamine whether backup failure is arranged, the taking-up formation is carried out, when the frequency of failure arrives the number of retries of regulation, revise backup instances and be designated " backup finishes " (can make exit condition simple like this, just judge whether the backup instances sign all is " backup finishes "); Finish if all BAM back up, this timer is just deleted self.At this moment, an automated back-up ground cycle has finished.
Supervision poll timer is still turning round again and again, waits for the arrival in next back-up processing cycle.
