According to the mail system backup method disclosed by the invention, complete backup and practical service data backup can be carried out according to requirements; if relative services are adjusted, the complete backup is unnecessary; the data volume for backing up relative contents is sufficiently reduced; the backup cost is reduced; and the backup efficiency is increased.
Description
Technical field
The present invention relates to the data backup and restore technology, particularly the mailing system backup method.
Background technology
Exchange Server (or Exchange) is the software about electronic message exchange and content cooperation, produce by MS, operate on the computing machine that serves as role server, for the transmitting-receiving work of the interactive communication content of the Email in the computer network and other form provides the platform support, be referred to as the microsoft mail system in the industry, abbreviated as mailing system.Current latest edition is Exchange 2010.
In the backup and reduction field, the mailing system backup and reduction all is to carry out at data content, if the mailing system structure changes in this case, will cause mailing system to reduce at present.In addition, this backup and reduction operation can only be carried out under same environment, can not rebuild mailing system by different machine, in these cases, most backup and reduction system requirements users build the institutional framework and the relevant configuration attribute of mailing system voluntarily, this has brought a lot of inconvenience for user's use, and simultaneously, complicated configuration parameter can make the user be difficult to rebuild accurately structure.Because other service linkages of mailing system service and Windows Server operating system are very tight, make for the backup-and-restore operation of mailing system very high for the control requirement of environment, existing at present backup product is often with the content-level backup of functional limitation under same environment, can not carry out reduction, more can not carry out different machine and rebuild reduction than complex situations.The prior art backup method is: but the file set of mails is served or directly backed up to the extension storage engine (ESE) of use mailing system, again the reduction that covers relevant catalogue during reduction or use ESE to serve the system of handling postal matter, this processing mode can only reduced under the same mailing system applied environment and under the relevant environment situation about not changing.If above-mentioned environment changes slightly, can bring following two problems: the one, do not back up the mailing system structure, thereby can't when structure changes, reduce; The 2nd, do not handle unmatched situation before the mails of backup and the reduction destination server, make reduction back cisco unity malfunction.
Use at present the mode of disk partition backup to back up in addition, specifically use the method for backup to replace mailing system, from realizing reaching the purpose with whole applied environment backup-and-restore, can bring more following problems in this way but make: 1, data backup amount is big.Because the range boundary of the data that uncertain related application is related has only backup subregion as much as possible.Promptly allow to determine, also can back up a large amount of irrelevant information, make backup efficient reduce greatly, the backup cost improves.2, system reducing has environmental restraint.If in environment and when reduction of backup,, inconsistent (source data, the purpose partitioned parameters is different, the related hardware driving is inconsistent) just can not reduce.3, can not upgrade the parameter of some total systems flexibly.Owing to this method has backed up redundant data in a large number, make the modification of relevant other application parameters have to return to over owing to reducing, the practicality of reducing is had a significant impact.
In sum, mainly contain the weak point of following several aspects at present at the implementation of Exchange backup and reduction:
The data integrity aspect: or the data backup deficiency, or data backup is too redundant.The concrete related data of using can not link closely.
Function practicality aspect: this is because the problem that data integrity can not be guaranteed and bring if the data backup deficiency can bring specific environment can not finish function, can be brought the problem that influences other application and data backup is too redundant.
Backup efficiency: if the too redundant problem that can produce backup efficient of data backup reduces system backup efficient, thereby influences the backup functionality practicality.
Summary of the invention
Technical matters to be solved by this invention is exactly the imperfect or too redundant shortcoming of data when backing up at prior art systems, and a kind of backup method at mailing system is provided.
The present invention solve the technical problem, and the technical scheme of employing is that the mailing system backup method comprises the steps:
A, service conducts interviews to mailing system, obtains mailing system nodal information and system version information;
B, the mailing system nodal information is carried out classification and storage;
C, each message database of mailing system is corresponded to interdependent node carry out classification and storage;
D, full backup Active Directory institutional framework and user profile;
E, back up other related service configuration informations;
F, backup are finished.
Concrete, among the step e, other related service configuration informations comprise POP3 service configuration information, SMTP service configuration information and Active Directory Services configuration information.
Further, among the step a, service conducts interviews using system keeper or domain name supervising person's user identity to Exchange.
Concrete, described nodal information comprises essential information and extend information.
Concrete, described essential information is the node name and the mutual relationship of node, described extend information is meant the attribute of each node.
Concrete, among the step b, according to node layer secondary clearing memory node information.
Further, among the step c, the mailing system server info in each message database of mailing system is stored in the ground floor minor node.
The invention has the beneficial effects as follows, can carry out the backup of full backup and actual traffic data as required, unless related service is adjusted, do not need to finish and reorganize and outfit part, fully reduce the data volume of backup related content, reduced the backup cost, improved backup efficient.To using the dependence of environment, this backup and restore method is only considered concrete DASE when the invention solves reduction, and is irrelevant with the place hardware environment.
Description of drawings
Fig. 1 is the schematic flow sheet of the embodiment of the invention.
Embodiment
Below in conjunction with drawings and Examples, describe technical scheme of the present invention in detail.
The problem that occurs in the mailing system redundancy technique, its essence all are the Backup Data integrity issues.If can accurately back up the application data of related service, can not cross redundancy can not data deficiencies, just can overcome the problem that occurs in the mailing system backup, and the present invention just is being based on this and is proposing a kind of full backup and the business datum backup method to combination.
Full backup is meant the process with all information full backups of Exchange service and each related service (SMTP, POP3, Active directory).Reducing by the mirror image that full backup is produced can the whole mailing system of complete reconstruction.
The actual traffic data backup is meant that on the basis of full backup mirror image only the associated mail database to the Exchange service backs up, and can dwindle BACKUP TIME and backup content so greatly.The Exchange service recovery can be specified the state of backup time simultaneously to the reduction of this part mirror image.
Mailing system backup method key step of the present invention comprises:
One, obtain the mailing system version information, according to version information, the hierarchical structure of mailing system is slightly different, and these information also can store reference when being used to reduce in the mirror image into.
Two, according to the version difference, obtain the essential information and the extend information of each node of associated mail system respectively, also obtain data simultaneously.If back up fully, need other service application datas of backup respective mail system interdependent node correspondence.
Three, essential information and extend information hierarchy and real data are stored into respectively in the different levels in the mirror image, the information of mailing system server can store in the ground floor minor node of mirror image.
Four, mirror image is classified according to the backup classification; content reduction and construction recovery and related service information have differentiation; when rebuilding reduction and reducing usually, to use respectively, use content to reduce then if the reconstruction reduction needs to rebuild structure and related service earlier according to the mirrored content difference.
The restoring operation of corresponding full backup and actual traffic data backup: can rebuild structure by reduction to full backup, finish and rebuild reduction, and just reduce the reconstruction structure before this need rely at the content of mailing system service for the reduction of actual traffic data.
Embodiment
Referring to Fig. 1, this example is the basic procedure of a full backup, below concrete steps is described in detail:
When 1, beginning mailing system backed up, the identity of first using system keeper or domain name supervising person user group conducts interviews to mailing system, and this identity can guarantee to obtain the information of all mailing systems.
2, adjust access rights, guarantee that the correct correct authority of identity use conducts interviews to data.
Each node of mailing system service has the setting for the designated user access rights, so possessing corresponding user identity, access node informational needs backup process guarantees correct visit, this information is adjustable, so this step is to describe the access security authority by adjusting specified node so that reach correct visit to data.
3, begin to travel through all institutional frameworks of mailing system, can difference be arranged on institutional framework because each version of mailing system is different, so will judge the version of mailing system earlier so that use correct operating process.
4, collect the information layered of all institutional frameworks and store, simultaneously also correspond to each node respectively and store for the content of the content of message database and Operation Log.
5, backup Active Directory.To the institutional framework layering in Active Directory storage, each user organizes following user and also corresponds to relevant group and store respectively.
Active Directory is the basic service of the territory control mode server of Windows proposition, is used for management domain user profile and relevant grouping information (the Mail store database that the inside has also comprised each user's mailbox message and has been subordinate to).
6, the corresponding relation of storage activities catalogue and mailing system message database, in Active Directory, write down relevant information, the separately backup and storing into again on the interdependent node of mailing system of this part informational needs is so that do user account correspondence accurately when rebuilding mailing system.
7, back up other relevant informations up to all related datas of whole coverings.
Information back-up comprises following plurality of processes fully:
The Active Directory information back-up.
Exchange service organization structure and e-mail messages content backup.
Mail other service configuration information back-ups of being correlated with.
Below main mailing system service organization's structure and the e-mail messages content backup described:
1) guarantees that backup process has group of administrators or territory control group authority.
2) be connected to the mailing system server of appointment.
3) the concrete version of definite mailing system server that connects, different follow-up actions have difference according to version, and main cause is that different editions mail server organisational level is different with structure, and version information is put into the ground floor minor node.
Access mail system server and obtain the information of each mailing system node and service that attribute is to use Microsoft to provide is carried out is mainly undertaken by CDOEXM (Exchange2003 and above version) and Exchange Management Shell (Exchange 2007 and later version) according to the difference of mailing system version.
4) obtain Public folder tree successively, Storage group information and corresponding attribute information, this information is put into second layer minor node information.
5) obtain each Mail Store DB that specifies under the Storage group successively, Public Store DB information and corresponding attribute information, the incidence relation sequence that simultaneously associated user's number of the account in the Active Directory (the corresponding Mail Store DB of a plurality of user accounts) is associated with Mail Store DB changes into data structure and puts into the tri-layer node as the extend information of Mail Store DB in the lump together with the content of describing before.
Annotate: the Mail Contents information of obtaining described herein is to finish by the service that Microsoft provides, difference according to version, Microsoft has carried out different recommendations, recommend to use ESE (Exchange stores expansion service) to obtain Mail Contents information for Exchange 2007 and following server, and Exchange recommend to use VSS to carry out document copying more than 2010.
6) e-mail messages among Mail Store DB and the Public Store DB being extracted sequence changes into Mail Contents information and also puts into the tri-layer node.
7) continue traversal Mail Store DB, the related down addresses of items of mail information of appointment Mail Store DB is extracted as Mail box information be placed on the 4th level node.
8) the Mail box of traversal appointment obtains inbox, outbox, and node such as draft and corresponding configuration and attribute information are placed on the layer 5 minor node.
9) recursive operation has then all write down up to all institutional frameworks of current mailing system server and each node of level, has just finished the backup procedure of mail server content and structure.
