Keeping your organization's data stored safely is a critical part of any disaster recovery strategy, and using remote replication to move data to an offsite location can offer a level of protection against data loss.
Remote replication has grown and can now be used throughout the data center for other jobs, like continuous data protection (CDP) and host failover support. In our podcast, Jeff Boles of the Taneja Group talks about remote replication's role in enterprise data storage and some of the available replication products.
Some organizations with more than one location choose remote data replication for disaster recovery. There are a lot of factors to consider when deciding if this approach is right for your needs. David Chapa, senior analyst with the Enterprise Strategy Group, outlines the pros and cons, what you need in place to facilitate this approach, how virtualization fits in, and the major vendors in this space.
Why do you need extra copies of your data? During a disaster, you may not have a functional primary data center, and in order to continue your business operation, you must restore the data using the data replication process. And having that copy of your data gives you the chance to at least pick up close to when you were impacted by the interruption.
