DRaaS vs. Legacy DR

Natural disaster, human error, the next nasty malware outbreak -- the dangers of downtime and data loss lurk around every corner. Add to that the fact that 24/7 uptime and accessibility has become a necessity for most businesses, this makes Disaster Recovery (DR) more crucial now than ever before. Because of these factors impacting today’s business environment and for its ease of use, many organizations have shifted their DR solution to Disaster-Recovery-as-a-Service (DRaaS). We’ll discuss the difference between a legacy DR solution and DRaaS to help you determine which approach is best for your business.

Before we dive into the types of DR solutions, we first want to establish why DR in general is a must for your business. Studies show that 54 percent of companies experienced a downtime event that lasted more than 8 hours in the past five years, and the typical daily cost of downtime averages $20k. Most companies can’t afford an hour of downtime let alone days, that’s why having a Disaster Recovery Plan in place is so important. A DR Plan defines how your organization’s IT infrastructure and applications will recover from a disaster so that you can avoid downtime and continue operations with little to no data loss. While your DR solution is only part of a complete DR Plan, choosing the right one for your business is critical for protecting your mission-critical data.

Legacy DR

Legacy DR involves hosting physical IT equipment at a secondary data center site. The solution works by continually replicating mission-critical data from a primary site to a secondary colocation location. The secondary site should be sufficiently distanced from the primary site so that one single disaster doesn’t affect both environments. While you could invest in building your own data center, most organizations accomplish DR by outsourcing to a colocation provider. If you choose legacy DR, ensure you have the IT skillsets needed to support testing and recovery, or combine your DR solution with managed services to get assistance from your colocation provider.


DRaaS is a Cloud-based DR solution that enables organizations to host their replication site within their Cloud Service Provider (CSP’s) infrastructure. This virtualized DR solution can complement a Cloud or physical environment and enables you to quickly standup a secondary recovery location into a primary production environment.

DRaaS is simple to deploy, support and failover, making it easy to perform testing and recovery on your own. Some DRaaS providers like Immedion also offer set-up assistance and access to technical support to help you implement, test and manage the failover process. If you’re considering moving to the Cloud, DRaaS can be a great starting point because it is low-risk and will allow your organization to become more comfortable with the Cloud.

Selecting your DR solution

Every company that has mission-critical data needs to have a DR solution in place, but you should carefully consider the differences when deciding between the two types of solutions. Follow the steps below to help you decide which solution is a better fit for your organization.

  1. Perform an internal risk assessment to determine what you need to protect your business against. Through the assessment, you’ll identify a list of your mission-critical assets and consider the potential impact of threats and vulnerabilities related to those assets.
  2. Determine if your business is able to run during and after a disaster
  3. Find out which solution your budget can support
  4. Evaluate your level of expertise. Will you need help developing, documenting and implementing your DR strategy?
