Disaster Recovery: Understanding the Path Forward

Disaster Recovery: Understanding the Path Forward

Dr. Alex Winokur, Axxana’s co-founder and chief technology officer, is a world-renowned innovator in the areas of data management, data protection, and storage. With more than 30 years’ experience and as an author/co-author of more than 15 patents in the areas of storage, network management, and telecommunications, he has not only helped shape the recent history of disaster recovery (DR) but is also instrumental in creating DR and high-availability solutions that are leading the way into the future.

His recent article, Disaster Recovery: Past, Present, and Future—published in the February 2019 issue of The NoCOUG Journal—takes a fascinating look at the technologies that formed the foundation for DR as we know it today, the historic events that escalated the need for more advanced DR capabilities, and the basic approaches that are currently in use. It also points out some of the key shortcomings of current approaches and discusses how they lead to protracted recoveries and longer downtime.

Drawing on details that aren’t typically conveyed in discussions of DR and application availability, the article provides a rich context for understanding the current state of DR and what is needed for the future. The article also suggests how organizations can use new technologies—including Axxana’s Phoenix—to overcome shortcomings and create a high-availability DR solution that ensures rapid recovery and continuous application availability.

Here are two important takeaways from the article:

Recovery point objective (RPO) is about more than data loss. The duration and complexity of the data reconciliation process (which must be performed whenever data loss occurs) is proportional to the amount of data lost. Organizations should think of recovery point objective (RPO) as the number of minutes of missing data that they will need to reconstruct and reconsolidate (i.e., reconcile)—not the number of minutes of data they are willing to lose. The higher the RPO rises (and therefore, the greater the data loss), the costlier the reconciliation process and the longer the downtime.

Typical DR configurations—including synchronous replication and cloud-based solutions—cannot guarantee zero data loss and therefore they cannot ensure continuous application availability. DR configurations that separate the primary and secondary center have predominated in the past decade or so; however these solutions cannot ensure zero data loss in rolling disasters and other disaster scenarios.  New cloud-based solutions reduce the costs and complexity of DR, but they too are incapable of ensuring zero data loss and continuous application availability. As climate change, terrorist threats, and cyberattacks escalate, organizations that want to thrive in the future will need to embrace artificial intelligence, machine automation, new approaches to cybersecurity, and revolutionary technology such as Axxana’s Phoenix.
