DRaaS: Emergency Data Recovery in the Cloud (IT Toolbox Blogs)



Over 93 percent of businesses integrate cloud infrastructure into their operations in various forms, making disaster recovery as a service (DRaaS) a logical next step in cloud adoption. In the event of a natural or man-made catastrophe, DRaaS can return a businesses’ IT infrastructure to service in as little 15 minutes — much faster than legacy backup storage systems. There are some things traditional backup systems can’t do. For everything else, there’s DRaaS.

Evaluating Risk Awareness and Resiliency

Choosing a DRaaS that fits your business starts with identifying your IT infrastructure’s weak points. Robust DRaaS providers, such as Microsoft Azure, Oracle Optimized Solution for Secure Disaster Recovery and IBM DRaaS, take an enterprise-wide approach to recognizing company weaknesses and resiliency in the event of a data catastrophe to produce tailored recovery solutions.

Detailed resiliency plans for enterprise-level DRaaS must meet industry and corporate benchmarks for business continuity, system security, disaster recovery and, in some cases, regulatory compliance on each layer of the resiliency framework — think of bank-level security, but for critical business data.

All businesses in the market for a fitted DRaaS program have essentially the same considerations, namely budget, staff resources, facility resources, tech level, amount of data and senior management’s take on the overall risk assessment.

After initial risk and resiliency assessments, vendors and clients develop a business impact analysis (BIA) to identify where to focus DRaaS resources and how to initiate a tertiary response. A complete BIA leads the way for recovery time objectives (RTO), or the time it takes to return to online status after an outage, and recovery point objectives (RPO), or how far back a business can sacrifice data in the event of an outage. For example, for a 15-minute recovery time, a business needs to upload their data to the cloud every 15 minutes. Upon defining a firm’s BIA, RTO and RPO, a vendor can get to the core of DRaaS: designing a cloud-based recovery plan that maintains business continuity as seamlessly as possible.

Business Continuity and Disaster Recovery

Cloud-based recovery plans vary in scope depending on business needs, which often correlate with business size. Small and medium businesses might need only file backups, whereas large firms often require a complete replication. Complete replication differs from backup in that it requires an identical infrastructure build out, and that’s where DRaaS gets pricey — DRaaS plans with replication can range from around $25,000 for a small business to around $3,000,000 or more for a large business. The cost of downtime should justify the cost of the DRaaS system, but if not, several out-of-box solutions are available to fit the needs of companies that lack either the budget, staff or maintenance capabilities to manage a robust system.

DRaaS for Small and Medium Businesses

Out-of-box DraaS systems typically prove beneficial to companies that lack the capital or technical expertise to configure, provision, test and maintain large-scale systems. Of the various out-of-box systems available, appliance-based DRaaS often prove the most feasible.

Appliance Based

 

The United States DRaaS Market Report 2015-2019 shows the DRaaS market leaning toward appliance-based systems, and for good reason — many small businesses simply can’t recover after losing their data. Appliance-based DRaaS works by connecting a specialized storage device to a business’s network that copies files and then moves them to the cloud. The transmission intervals vary according to vendor plans.

Data is too valuable to lose to man-made disaster, such as a cyberattack or a natural disaster — think tornadoes, earthquakes and anything considered an “act of God” for insurance purposes. If your business has minimal data-recovery options, explore DRaaS providers and find the plan that’s right for you. You might not have an opportunity to replace lost data otherwise.
