Disaster Recovery as a Service (DRaaS) Explained

Posted by QuoteColo on January 12, 2018 - Updated on December 12, 2017

You may be surprised to find out that disaster recovery (DR) was one of the first cloud-based IT services to become a real hit. When DR on the cloud was new, it was an alternative to replicating physical servers and backup tapes, both of which were expensive. Nowadays, the idea of using the cloud, even to move an entire infrastructure, is commonplace and barely warrants an eyebrow raise.

Disaster Recovery as a Service (DRaaS) has grown leaps and bounds in popularity since the early days. In fact, Gartner Inc. believes that organizations and businesses using DR as a cloud service will take over the amount who use traditional recovery systems by 2018

The Change to Cloud

DRaaS allows an organization to outsource their data recovery to an external provider using the cloud, rather than going through with setting up a new data center to do so. With this method, data is refreshed and replicated to the cloud where it remains unless it needs to be activated due to a disaster situation declared by the business.

This is great for smaller companies, as well as larger ones, because it carries no requirement to invest in an off-site facility. With the constant increase in security breaches, having the ability to move operations elsewhere in a quick and reliable way is a critical thing. DRaaS takes that seriously and gives organizations a better option.

Managed Services

It can be smart for IT managers and staff to free themselves up from routine jobs like backups in order to spend time on innovative processes. Things like DR, storage, replication, and backup are known for taking a lot of time and money. By using a cloud hosted alternative, those IT staff have more time to spend on projects that give value to the business.

This is one of the reasons that DRaaS is a great option for medium sized businesses that may not have the expertise to test, configure, and provision an efficient and effective disaster recovery plan.

Business Impact

Some CEOs and other bosses are iffy about investing in DR because the need for it and the downtime it will represent is not a fixed factor. Because of that, it can often be a contender for removal in budget cuts. The problem is that by having no disaster recovery plan, when a disaster does strike, it may cost much more than the DR plan would have in the first place.

One way to work around this is by carrying out a Business Impact Analysis (BIA). This is where you would define recovery point objectives (RPOs) and recovery time objectives (RTOs), which help to identify critical IT data and assets. When choosing a DRaaS vendor, you should also be sure they are aware of the objectives and are willing to stick to them during implementation.

Having this information available regarding RTOs and RPOs will provide you what you need to talk with various IT providers to determine if they can meet your needs and give you the best solution for your recovery needs.

Looking Forward

While disaster recovery has come a long way, it’s also not something you can implement and then ignore. Your internal IT department will still have things to do, even with a DRaaS provider.

It also doesn’t make it unneeded to have strategies for preventing disasters, as it’s always better to avoid these situations if it’s possible. IT managers still need to be cautious and do what can be done to avoid emergency situations. Disasters, or just disruptions, can occur any time and being prepared is something that is important.
