The prospect of an IT outage is one of the key issues that keep IT professionals awake at night. From natural disasters to malicious cyber-attacks, organisations face an abundance of risks to business continuity that impact productivity, prosperity, financial stability and reputation.
These worries have only been exacerbated in recent months as the Covid-19 pandemic continues to have an unprecedented impact on worldwide economies, trade and the survival of individual businesses.
Therefore, it’s never been more important for these organisations to take the necessary steps to protect their business from any of the above scenarios, which have become increasingly prevalent.
Despite these constant threats, customers want assurances that their day-to-day operations will not be impacted, should a partner business suffer a loss of data or significant business disruption.
IT resilience powering business continuity
With nearly every organisation on earth dependent on some form of technology and connectivity, the term ‘IT resilience’ is directly intertwined with the resilience of the business in a time of crisis.
The strength of an organisation’s cloud or on-premises infrastructure is its backbone; therefore, if it fails or suffers an outage, many subsequent businesses could suffer significant business disruption.
Organisations develop business resilience plans so they can rapidly adapt when disruptions occur, helping them to maintain business operations, in addition to keeping data, staff and the company’s reputation safe.
This should be teamed with IT resilience, to continue business system operation no matter the disruption. Many organisations will instantly think of maintaining backups when they hear of business continuity. And to some degree they are correct.
However, that’s only part of the problem; Disaster Recovery (DR) and Disaster Recovery-as-a-Service (DRaaS) has been increasingly adopted to protect businesses against outages, through infrastructure and strategy that deals with worst-case scenarios.
While many organisations align the term ‘Disaster Recovery’ with a natural disaster or potential meteorite strike that threatens human life, a software fault, malicious external hack, subsequent data breach, or a careless accident initiated by an insider can be equally disastrous from a business disruption perspective.
Moving from backups to Disaster Recovery
Business resiliency is all about the ability to bring your organisation online to another location as quickly as possible to continue to run your business and support your customers internally and externally.
Whilst backups are key to protecting data, maintaining archives and compliance, they must be layered with a DR capability to reduce the chances of a business being disrupted.
The disadvantage of backups, especially when organisations try to recover quickly, is that they are prone to unacceptable Recovery Point Objectives. If a business is only backing up every night and something happens an hour before the backup, an entire day of workloads will be lost.
Also, backups can have painful Recovery Time Objectives. If it takes 17 hours to recover an organisation’s entire data centre from tapes, in addition to how long it has been down for, that’s a considerable amount of time.
Furthermore, local backups can be targeted by malicious software, which targets backup applications and database backup files, proactively searching for them and fully encrypting the data.
Backups also need something to restore to; if the power fails in the building where the business’ data is housed, backups are not going to help.
This is where a cloud-based DRaaS solution fills the gaps. It is a flexible, cost-effective way to deliver essential DR capability without all the CAPEX costs and pains of managing a physical DR site.
At the press of the button, a business can instantly switch to its DRaaS environment, with an isolated, production-ready copy of its entire infrastructure available in the event of unplanned downtime or data loss.

Furthermore, with regulations such as GDPR and CCPA increasing in popularity and becoming more stringent, DRaaS helps organisations to illustrate that they have taken all necessary steps to protect their customers’ data, giving them confidence that should the worst-case-scenario happen, their data – and business – will be protected.
With DRaaS, teams can run recovery tests in replica environments in a short time, providing full visibility into a business’ response during a ‘disaster’. This is much more effective than annual testing of on-premises systems, helping businesses develop a full disaster recovery plan with absolute confidence it will work when needed, minimising potential downtime.
Quickly enacting these DR plans will only increase this confidence. Quick and coordinated response amid an outage will increase customer faith in the organisation that it can instantly switch to a cloud-based data centre if any of the primary equipment fails.
Downtime will be increasingly disruptive
In the world we currently occupy, many businesses are facing an unprecedented financial crisis due to the Covid-19 pandemic that is driving them out of business. For example, in retail, many have shifted to, or quickly started to offer, improved eCommerce channels, allowing them to deliver their services or goods to customers.
Regardless, this has led to shrinking revenues and severe tightening of budgets.
Therefore, the last thing a business needs is any unscheduled periods of downtime due to IT systems going offline. This goes hand-in-hand with the online attack surface widening in many industries, as cybercriminals take advantage of the current global climate, ramping up their efforts to cause further disruption and distress.
This is why DR is increasingly critical. Customer experience rests upon IT systems; interruptions of service, inability to transact, and data loss can be frustrating, debilitating, or even life-threatening in certain industries.
Organisations should also think about the costs of downtime and the perception of customers should a vital application be down, especially during a time when a global pandemic is having a knock-on effect throughout the supply chain.
Acceptable amounts of downtime and data loss are at an all-time low, and recovery features that were once considered ‘nice to have’ are now mandatory.
With the emphasis of IT resilience on maintaining business processes and making a complete recovery as soon as possible, it’s no wonder that DR is becoming increasingly mission-critical to day-to-day operations.
Taking the necessary steps to overcome business disruption when faced with a potential ‘disaster’ will easily outweigh the initial financial outlay of implementing an effective DRaaS solution.
