Hybrid Email Archiving Offers an Alternative to On-Premise and Hosted Email Archiving

Email archiving is a critical data center application. Email archiving is usually located on premise, but hosted archiving is attractive because it reduces up-front server and storage costs and simplifies IT support efforts.

A hybrid approach should also be considered. This manages email locally before it moves to the cloud for long-term retention. Email remains accessible and can be returned to local storage for legal discovery. The main advantage of the hybrid approach is that it provides the performance of local email archiving while leveraging cloud storage to reduce total storage costs.

Several vendors offer a hybrid approach to email archiving. Autonomy was one of the first with a combination of Digital Safe hosted email archiving and EAS on-premise email archiving.

Iron Mountain is a new market entry and combines its existing hosted service with the Mimosa NearPoint on-premise email archiving solution. Iron Mountain recently acquired Mimosa, and one of the reasons for its purchase was so Iron Mountain could offer this hybrid approach to email archiving.

    Thanks for posting the same. Just curious to know as to how much is the advantage in terms of cost given now one needs to pay for the cost of on-premise as well as hosted service.

    You are correct to question the cost of the hybrid approach. It does require payment for both. But the advantages may out weigh the cost. In my estimation the driving force is the need for long term email storage, and it must be kept very secure (resisit any tampering) for legal purposses. With a hybrid approach, you can manage near term email records, say 1-2 years, and manage the long term email, say 2 to unlimited) off host in a secure data center. The offsite storage offers ‘capacity on demand’, no management cost for HW and provisioning, and security.

    Exchange 2010 SP1 makes it very easy to enable this hybrid approach.
    The Mailboxes can placed on data volumes that are backed by local data-center storage while the archive folders can be placed on volumes which are backed by cloud storage.
