Disaster recovery (DR) is an essential part of keeping data safe and maintaining business continuity. However, with so many different options of disaster recovery plans that a business can implement out there, the process of finding the best fit can be overwhelming. Each business is different, so it’s important to understand all of the choices available to you. This way, you can pick which plan best suits your needs. To help you out, here’s what you should consider about four types of disaster recovery plans:
Data Center Disaster Recovery
In this approach, the disaster recovery plan is not just limited to the computing facility it’s housed in. The entire building plays a large role in data center DR. Features and tools within the building, such as physical security, support personnel, backup power, HVAC, utility providers, and fire suppression all have an effect on data center DR. In the event of any sort of outage, these elements within the building must be in working order. With these components working, your data is at a lower risk against intruders and cybercriminals. However, even if everything is functioning correctly, your data center can still be susceptible to a natural disaster.
Cloud-Based Disaster Recovery
When using a cloud-based approach, you’re able to cut costs by using a cloud provider’s data center as a recovery site, rather than spending more on your own data center’s facilities, personnel, and systems. Users also benefit from the competition between cloud providers, as they continue to attempt to best each other in the market. Before committing to this method, determine the challenges that providers may have with your business’ backup and recovery. The provider may be able to assist you in fixing those problems before the cloud becomes a part of your DR plan.
Virtualization Disaster Recovery
Virtualization negates the need to reconstruct a physical server in the event of a disaster. You are also able to achieve your targeted recovery time objectives (RTO) more easily by placing a virtual server on reserve capacity or the cloud.

Disaster Recovery as a Service
While Disaster Recovery as a Service (DRaaS) is often based in the cloud, it is not strictly cloud-based. Some DRaaS providers offer their solutions as a site-to-site service, in which they host and run a secondary hot site. Additionally, providers can rebuild and ship servers to an organization’s site as a server replacement service. On the other hand, cloud-based DRaaS enables users to failover applications immediately, orchestrate failback to rebuilt servers, and reconnect users through VPN or Remote Desktop Protocol.
When looking for a DRaaS solution, be aware that some providers offer their own products, while others use DRaaS tools from partner vendors. In the case of partner vendors, inquire who your provider’s partners are, as well as what products they’re using. It’s also helpful to know where your provider is located and what their data center resources are. This information will give you some insight into what the vendor’s capabilities will be in the event of a regional disaster.
Creating a comprehensive disaster recovery plan is difficult, but that doesn’t mean it has to be impossible. Find which approach is the right fit for you and your organization. After doing so, your data will be safer from cyber-attacks, natural disasters, and simple human error.
