Ishin: The relationship between mail archiving and mail backup

With each unit in the process of information construction of the gradual attention to security, data security has been reflected in the eyes of the network management personnel. As the main carrier of the unit data interaction---mail system, the large amount of data generated in the daily application process naturally becomes the primary protection object. However, two things related to the security of mail data: Mail backup and mail archiving, but it is interfering with the thinking of many network administrators. In order to make the network management personnel can clearly understand the difference and relevance, the author in this special in-depth analysis. Mail Backup: As the name suggests, a mail backup is a backup and copy of the information that is currently stored on the mail server, the mail account, and other messages. Most of the technology uses disk mirroring to copy and back up existing information and data in the mail server disk. The goal is to respond to system recovery after a catastrophic failure of the messaging system. When a catastrophic failure occurs in a message, a mail backup can restore the most recent point-in-time backup to the mail server, allowing the mail server's status to be restored to that point in time, thereby preventing the mail server from becoming paralyzed. E-mail archiving: Mail archiving is the e-mail system generated by real-time, complete the recording and preservation of electronic mail, convenient at any time to fine-grained retrieval and access. To respond to individual message loss recovery, key events, electronic evidence and related regulations requirements. Differences and relationships: the object of a mail backup is the data and files on the mail system disk, and the Mail archive is targeted at all mail entities that are currently generated by the messaging system. Because of the different implementation mechanism, its utility is also very dissimilar. The Mail archive cannot record the current state of the disk in the messaging system and can not back up and restore information about the accounts in the mail system. Due to the fluidity of the mail data, the mail backup cannot guarantee the integrity of the message as well as the mail archiving, and can not access and recover the message. The Mail backup system can not realize the electronic proof, individual message recovery and meet the regulatory requirements. The complementarity of mail archiving and mail Backup is an indispensable part of guaranteeing the absolute security of mail data. Of course, network administrators can also according to their own units of actual situation and needs, targeted choice of their own mail data security program.
