Sending a copy of your data offsite is rule number one for IT disaster recovery planning. Now that remote data replication technology

has become widely available -- often available as a feature of storage
hardware or backup software -- many organizations have opted for it as an alternative to shipping
tapes offsite. We've put together this list of our five favorite data
replication tips we’ve published this year. You’ll find advice on VMware vSphere Replication
for Site Recovery Manager, host-based replication products, and learn about the differences between
asynchronous
and synchronous replication.
Tip #1
Replication technology for business continuity and disaster recovery
In this podcast, Enterprise Strategy Group Senior Analyst David Chapa shares results and insights of his report, “Replication Technologies for Business Continuity and Disaster Recovery,” including disaster recovery trends, components of those DR plans, and why it’s a good idea to use data replication technology in disaster recovery.
Tip #2
A look at VMware vSphere Replication for Site Recovery Manager 5
This tip will help you understand VMware vSphere Replication for Site Recovery Manager 5. You’ll learn how it works and what you need in order to deploy it in your organization.
Tip #3
Replication technologies: Asynchronous vs. synchronous replication
Whether it’s replicating virtual machine images for data protection and high availability or exchanging information with cloud services, data replication has grown in popularity. That said, it’s not easy to select the right data replication technique. This tip looks at asynchronous and synchronous replication, as well as the positives and negatives of each technology.
Tip #4
Data replication solutions: Host-based replication products
While host-based replication offers minimal entry cost and complexity when looked at alongside other data replication solutions, these rise exponentially as the number of replication nodes increases. It’s relatively simple to manage for a small number of servers, but managing a large number of nodes -- from initial install and rollout through ongoing support and monitoring -- is much more challenging. This tip will show you the pluses and minuses of host-based replication offerings.
Tip #5
Using remote data replication for disaster recovery
If you are thinking of adopting remote data replication for disaster recovery, there are a number of questions you must first answer. How big is your organization? What type of organization? Bandwidth requirements are just one of the many factors to consider. This FAQ features David Chapa, senior analyst with the Enterprise Strategy Group. He looks at the pros and cons of using data replication as part of your DR strategy, what you need to make this approach a reality, how virtualization enters the equation, and the key vendors you’ll want to know.
