There are lots of reasons to protect Microsoft Exchange. A few “whys” and move on to “how” in fact, one could probably devote an entire article to simply building the case for Exchange protection; but instead, let’s simply list.
* It might be argued that no application touches as many elements of a business as Exchange. From the delivery space to your executive boardroom, nearly every working job function has some level of dependency on email server hosting. Hence, when the e-mail server is unavailable, the entire organization is affected.

* With regulations like Sarbanes-Oxley, also those related to monetary and healthcare organizations, the retention of email has become an responsibility that is ethical of’s career. Other laws, such as E-SIGN, bind electronic agreements with the same validity as penned contracts.
* And finally, while the above two examples are “internal”, many companies rely on e-mail as part of doing business, externally today. From distributing information between time zones, to coordinating a lunch location, e-mail is now often the most critical business communication for some businesses.
Therefore, the question becomes “How can I effectively and affordably protect Exchange?” Before considering solutions, one should understand the difficulties first around protecting Microsoft Exchange.
* Exchange data is held in numerous directories with excessively interdependent that is large. In even the most simple configurations, tens to hundreds of mailboxes can be stored in a single “information store” file.

* Exchange data are constantly in usage and remain open by the application form. Even though the files could possibly be sporadically closed, the 24X7 use of e-mail requires them become available all of the time.
* The above two facts combined require a window that is”backup and specialized, and typically expensive, software (called backup agents) to look in the apply for traditional back-up.
* And to make things more complicated, the existing variations of Microsoft Exchange (2000 and 2003) are influenced by Windows active directory. This necessitates other external information to also be protected in order to guarantee the resilience of one’s e-mail system.
Collectively, its safe to state that Microsoft Exchange is perhaps very difficult applications to back up. For that good explanation, many IT administrators have begun looking at different choices for Microsoft Exchange protection and access.
From a “protection” perspective, tape backup is assumed. However, as one steps enough time and effort needed to backup windows and restore tapes, we’re forced to concede that tape backup alone is insufficient–when you consider that tape back-up does occur only nightly, which could bring about up to an day that is entire of loss should a failure occur. In the instance of email, much of that information loss is unrecoverable. After which, during times of restoration and crisis, recovery from tape is usually measured in hours.
