E-mail archiving system of how the deployment
: Xin Hao
successful deployment of an e-mail archiving system for e-mail system and the need for enterprise e-mail archiving system for the characteristics of a comprehensive test, and the need to the actual situation of enterprises and enterprise business growth brought new pressures to adjust, take full account of stability, usability, security and scalability needs.
how to implement the deployment of e-mail archiving system and product selection has a very high degree. a successful deployment need to prepare the test phase, for the corporate mail system features and characteristics of e-mail archiving system to test, and the need to consider the actual situation of enterprises, enterprise business growth under new pressures to adjust, take full account of stability, availability, security and scalability needs.
this paper, Quest Software's Archive Manager 3.7 For Exchange deployment and application of the explanation. Archive Manager is an enterprise application for e-mail archive management tool that can automatically merge mailbox data to the economic security of their archive storage system for security auditing to provide a reliable source of data. Archive Manager For Exchange independent of the Exchange server through Microsoft's Journal Mailbox feature functionality of the mailbox-enabled Journal mail store archiving, and e-mail through its unique separation of functions, the body of the message and attachment separation, respectively, stored in a SQL database and file system.
different physical topology of the Archive Manager enterprise scale deployment of some choice of different items, so creating different solutions.
structure for a single site within a site or a single business enterprise exists between the bandwidth of the site with better conditions (Figure 1). Under these conditions, the number of users decided to choose server hardware . Also note that large enterprises tend to have more comprehensive disaster recovery plan (DRP), so the message archive server can also load balance the cluster model or (NLB) mode to increase availability.
existence of the business for more than the physical structure site (Figure 2), and the higher the bandwidth between the corporate site, the case of low utilization and remote access site, a relatively small number of users (<100).
to reduce bandwidth consumption, Archive Manager can configured in accordance with the schedule for mail archiving functionality mode. If the remote site has been installed Exchange mail server, can be configured to enable the mode of the local Diary (Journal Local) e-mail archiving to reduce the bandwidth consumption.
If an enterprise has multiple sites, and the number of users per site over 100 people, and network bandwidth are limited, then the distributed structure is the most suitable site of a scene (Figure 3). As a distributed resource sharing between sites does not exist Therefore, compliance and email storage strategy needs to be set independently at each site. Of course enterprises according to their actual situation, the above several scenes for the deployment of hybrid topology.
hardware and software planning < br> In general, we will run the e-mail archiving service called e-mail archive server, the server, its main function is as follows:
1. ArchiveManager_Journal mail services through the implementation Dataload message load;
2. with the directory service synchronization ;
3. the message content and attachment index;
4. interact with the Exchange ESM, the establishment of mail storage policy views or through the mail storage delete.
Archive Manager after receiving the e-mail archiving, mail processing engine will be recorded, and the message body and attachments are saved, the text messages stored on a database in SQL Server, attachment to a particular form of saving a file server, the association between the two kept in SQL Server, Therefore, the database server to play a very important role, its configuration refer to Table 1.
e-mail archive server, database and accessories storage space considerations mainly based on the number of customers, and archive storage retention period requirements. which must be stored in the local database DB Raid 5 SCSI hard drives or other high-speed SAN storage devices, and accessories can be stored in a number of slow storage devices.
e-mail archiving system in the formal deployment, you need to combine the needs of the software and do the appropriate check list, usually including, but not limited to these points: 1. Check the system environment; 2. Configure anti-virus software; 3. configure the firewall; 4. configure DNS records; 5. configuration database; 6. configuration archive service accounts and groups; 7. Configure account permissions; 8. enable the Envelope Journaling.
e-mail archiving system for archiving strategy
ultimate goal is to meet the enterprise application in the mail archiving. According to market feedback, the main e-mail archiving applications include e-mail content security audits, e-mail attachment security audit, mailbox storage optimization, backup redundancy, and user self-service email archiving.
archiving strategies are used to manage mail server, e-mail through different strategic decision information can reside on the server the length of time. These strategies can also be used to reduce the size of message storage, Archive Manager's strategy is very flexible and can be based on the organization, it can be based on the user object.
archiving strategy acts include:
Export (Export): back up data from the Exchange mailbox store to the Archive Manager database, this is the common strategy;
Remove (Delete): Delete the data meet the policy conditions, this strategy requires caution;
stripped (Strip): only from the Exchange mailbox delete data stored on, but not in the database from the Archive Manager to delete, when needed, the user's mailbox in the Exchange store on the reconstructed data.
mail retrieval
message archiving system for e-mail retrieval is an important function. a good filing system will need to meet security audit, information security and other needs. Archive Manager e-mail search capabilities powerful, privileged users can use the Archive Manager built-in search tool to quickly search for archived messages. Archive Manager can also and the implementation of full-text e-mail attachment, usually in a very short period of time will be able to find the required data from the mass of information. Archive Manager allows users to retrieve e-mail not only metadata, message content and attachments, it also extends these capabilities, such as To, From and Subject fields and other meta-data can be retrieved, and for the external and internal mail can be retrieved. message contents and attachments via a standard keyword search. The user can enter a keyword or certain key word combinations. the message content and message attachments will be retrieved.
summary, a good e-mail archiving system can achieve business compliance, optimize the mailbox store and the realization of e-mail monitoring, and many other features. deployment and application of e-mail archiving system to fully consider the characteristics of products purchased, and requires a combination of enterprise management strategy and the actual situation, given a reasonable deployment architecture to achieve the full application of e-mail archiving system.
