The continuity of e-mail is not much thought, but when Gmail has recently experienced a server, millions of productivity has been lost and sudden e-mail continuity and email archiving were the hottest topic.

E-mail always available is not what the typical user thinks, but e-mail archiving is a critical requirement for every organization to help ensure email continuity. It is essential to be centralized and secure. Email archiving should not only store e-mails for registration and compliance, because businesses can no longer afford to stop emailing for any time.

One & # 39; always-on & # 39; in the world where access to email is self-evident. Like breathing, access to emails is always the same as always. We expect that our BlackBerry devices, iPhone, laptops, computers, all over the world will be able to access our e-mail from an internet café and anywhere. E-mail continuity is not a word in our profession, but it is exactly what we expect.

E-mail systems are more complicated than people's comments. In fact, little attention is paid to what can happen when you press sending. When an email arrives from a device, it usually navigates directly to the server on a route using a number to access the server. The use of the name causes less delay and no one can notice that the email path must be checked in DNS. DNS is the system that contains all information about all domains and subdomains. Each domain (and some subdomains) has unique e-mail information that is first found in e-mail continuity systems.

The DNS query of the MX (mail exchange) record occurs and most systems have an address. The bigger ones have two or three to ensure that if an email server falls, another can accept the e-mail on its behalf, deal with it, store or forward it, otherwise it may be the exact clone of the seized system, seamless e-mail continuity services. This search is an important part of making e-mails always accessible to people, because at this moment, if there is a problem with the main server, something may happen wrong. If a backup is available – even if it is not a mirror system, it means that few will notice that anything has changed.

In our world, where we are always waiting for e-mails and where businesses are indispensable, mirror servers are more common. These systems cause a hot failure when the system stops ensuring that they move smoothly from one physical server to the other while one is being used by another wizard during repair. This is expensive email continuity. The less expensive option of providing a kind of e-mail continuity is the transition to a separate e-mail archiving system that often sits on another server on the same rack (which is risky) or on another server site or cloud. This is a safer way to ensure real e-mail continuity because the servers are physically located in different locations.

E-mail is never more important than ever. E-mail continuity is expected, and no matter how complicated it is, IT departments are only preparing to create a reliable system.
