DR needs differ from company to company. Each organization has its specific DR requirements, and out of those have emerged two distinct types of Cloud-based Disaster Recovery services. These are:

1- Cloud DR

2- Disaster Recovery as a Service, or DRaaS

While some users erroneously use these two terms interchangeably, it is important for organizations to have crystal clear knowledge of the differences between the two so as to make the right choice.

It is the CIO’s duty to ensure that the mission-sensitive and critical data of their business is safeguarded and secure against issues such as outages or downtime. Along with that, the business must keep running without facing any issues during times of disaster. However, everything is not rosy during such turbulence and even the toughest infrastructure may give way, leading to loss of business and tarnished reputation.

And that is not all, folks! In today’s world, business continuity and 24/7 availability is imperative. Inaccessibility is an unimaginable scenario for all companies. Now, in such an edge-of-the-seat situation, the buck stops at the speed at which the DR plan chosen by you helps your business recover post a disaster. So, you do realize the importance of having a robust DR plan in place.

Earlier, most data centers offered DR plans which remained idle till catastrophe time for most businesses. However, keeping the objectives of time paucity and round-the-clock availability in mind, DR has moved to the Cloud. This move has increased the efficiency, scale, and speed at which a plan will execute for its business. The best part here is having the plan set secure in the Cloud also allows the clients to safeguard themselves from disaster aftermath, and the management aspects become much easier than before too.

DR services un-encoded

If we go just by definition alone, both Cloud DR and DRaaS lead to realization of two aspects – data recovery and availability, along with supporting the business continuity strategy of the client.

Cloud DR is the traditional method of taking regular backups of data and applications and keeping them in a cloud environment for recovery in a disaster scenario. However, it does not replicate a live IT environment.

DRaaS goes a step further. It adds a tailor-made failover service to this backup and disaster recovery scenario. How it does this is by allowing the client business to mimic its computing environment on a virtual private cloud, a hybrid cloud, or a public one. The client can easily access this environment through the internet and manage it through a web portal. So, all the applications are up and running almost instantly, without the loss of time or business.

Subtle differences

Cloud DR offers tremendous flexibility to the client organization, which is totally free to set up its own parameters for data backups and archiving. It helps businesses to eliminate several cumbersome procedures and practices and offers them wings to keep testing and retesting data recovery speed and business availability so that when the time comes they would know where they stand.

The two aspects CIOs must ensure before going in for Cloud DR is safe and secure data transfer and proper user authentication. They also need to check if they have the necessary bandwidth and capacity to be able to successfully transfer or redirect users to the Cloud when the time comes. The last item on the to-check list is the correct details of data recovery spelled out crystal clear in the plan.

Again DRaaS takes this a step ahead. On top of all that, it needs very few resources. This helps the companies save enormously in hardware equipment and obtaining software licenses. All recurring costs are taken care of and managed by the provider. Also, the provider takes care of facilities such as bandwidth and power which they are able to provide on the back of their advanced data center. With DRaaS, the client will pay just for the usage of the facilities, which makes it more cost-effective and scalable than traditional in-house DR setups.

However, this also makes it slightly more expensive than Cloud DR facilities.

When it is crunch time and you are wondering which service to go for, just ask yourself one question – how flexible would your company be in terms of data and time loss during a disaster. If you feel your business would not be able to take any kind of hit whatsoever in any form, DRaaS is a better bet. Cloud DR is best for organizations that have a wee bit of flexibility in their operations, those that can allow for some loss of time or business availability post a catastrophe.

So, now that the differences, however small, between these two types are clearer, it would be easier for you to take the right decision for your business.
