Cloud computing causing rethinking of disaster recovery

Cloud computing gives organizations the opportunity to rethink many traditional IT practices, but it may be a particularly good fit for disaster recovery and business continuity. Network World Editor in Chief John Dix caught up with IBM Distinguished Engineer Richard Cocchiara, who is CTO and the Managing Partner of Consulting for IBM’s Business Continuity & Resiliency Services, for his perspective on the subject. Cocchiara leads a worldwide team who work with clients on systems availability, disaster recovery planning, business continuity management and IT governance.

What are the different roles cloud can play in disaster recovery and business continuity?

Probably the most basic thing is backing up data offsite. Most large companies have some sort of a backup strategy, but more often than you might think we find companies who are not sending their data offsite or not sending it far enough offsite. When we ask if they have checked to see what potential regional issues they might have, sometimes they find some geological or weather or some other type of potential risk that would affect their ability to recover locally. Cloud gives them the ability to store data some place remote, store it online, and to typically recover faster than from tape.    

Then there are services that allow clients to fail-over servers. The cloud is very good now for Wintel servers, where you can replicate your data and fail-over relatively quickly. So in addition doing replication of data to another server, we still recommend backup because you can recover individual files to a point in time. With server replication you will fail over, but you may not be able to go back as far as you want unless you’ve got a facility such as our Virtualized Server Recovery, which allows you to take snap shots.
