World Backup Day: the role of backup in business resilience and continuity

Every 31 March marks World Backup Day, an initiative that highlights the importance of backup and data protection for organisations. Traditionally, backup has been a standard practice in IT management: creating copies of data so they can be restored if an issue arises.

Today, that approach is no longer enough.

In a digitalised business environment, the role of backup has evolved. Organisations are increasingly dependent on digital systems, generate ever larger volumes of information and operate across hybrid environments where on premise infrastructure, Cloud services and SaaS applications coexist. In this context, protecting data is essential to ensure business continuity.

At the same time, the risk landscape is becoming more complex. Cyberattacks are a constant threat, but they are not the only one. Infrastructure failures, human error or disruptions to critical services can leave systems unavailable and lead to significant financial, operational and reputational impact.

■ As a result, backup is no longer just a preventive IT practice. It has become a core component of resilience and business continuity strategies across organisations and public sector bodies.

Backup is fundamental to business resilience.

Why enterprise backup has become critical: more data and greater risk

The evolution of backup is closely tied to the growth of business data. According to Gartner, global data volume will exceed 300 zettabytes by 2030, driven by digital technologies such as IoT, AI and Edge Computing, among others.

This surge multiplies the volume of information that organisations generate, store and use, making it increasingly difficult to manage and protect.

As data becomes embedded in critical business processes, any incident that affects its availability has a direct impact on operations: systems go down, services are disrupted and processes come to a halt.

At the same time, cybercriminals have made data one of their primary targets. A clear example is the rise in ransomware: attacks designed to block or seize corporate information and demand payment for its release.

In this context, ensuring data availability and rapid recovery is essential to maintain operations and safeguard business continuity.

■ For this reason, traditional backup approaches based on isolated infrastructure or manual processes are becoming less effective. As Gartner notes, organisations are moving towards data protection models built on services that protect information where it resides and manage it in a unified way across hybrid and distributed environments.

Data availability has become an operational requirement for the business.

The evolution of enterprise backup: more flexible and managed models

The growth in data volumes and the increasing complexity of technology infrastructures are driving a shift in data protection strategies. Organisations now require solutions that can adapt to distributed environments, scale quickly and provide clear visibility into the status of protected data.

In response, the market is moving towards more integrated and flexible approaches. Gartner highlights that many organisations are adopting Backup as a Service (BaaS) models, enabling them to manage data protection from centralised platforms while adapting to data growth and increasingly diverse technology environments.

These solutions simplify operational management and make it easier to protect distributed data across different systems and applications. They also allow storage and recovery capabilities to scale in line with business needs, without requiring backup infrastructure to be redesigned.

They also incorporate capabilities that strengthen system resilience, such as immutable storage, isolated recovery environments (IRE) and anomaly detection mechanisms to identify incidents such as ransomware attacks and accelerate recovery processes.

■ In practice, backup now forms part of a broader data protection strategy: a set of capabilities designed to ensure that, in the event of a disruption, systems can be restored quickly and operations continue with minimal impact.

Backup has evolved from infrastructure into a data protection and business continuity service.

The role of backup in business continuity

To achieve this recovery capability and minimise impact, organisations need to develop business continuity plans (BCP) that define how to respond and how to restore critical systems and services in the event of disruption.

Every continuity plan begins with a risk analysis to identify potential threats to the business and assess the impact of disruptions to critical systems and processes. From this analysis, key indicators are established to define recovery objectives.

Among the most widely used are:

• RTO (Recovery Time Objective) indicates the time required to restore a system after a disruption.
• RPO (Recovery Point Objective) defines how much data can be recovered without significant loss.

These parameters help determine which strategies and technologies should be implemented to ensure operational continuity.

Continuity strategies bring together different technological capabilities to respond to incidents and restore services quickly. They include backup, integrated with technologies such as data replication, high availability for infrastructure and applications, and disaster recovery services (DRaaS).

■ Through this combination of capabilities, systems and data can be recovered after a disruption. This reduces the impact on business operations and allows activities to continue as normal.

Backup is a key component within a comprehensive business resilience strategy.

From backup to business continuity: our approach at Telefónica Tech

As data has become a fundamental asset for business operations, at Telefónica Tech we address this challenge through a comprehensive technological resilience approach. Backup is an essential capability within this data protection and business continuity model, integrated with other technologies designed to enhance system availability and recovery.

Our approach is complemented by solutions such as data replication, high availability for infrastructure and applications, and disaster recovery services. These capabilities enable systems to be restored, critical information to be recovered and operations to be maintained in the event of incidents or disruptions.

■ This approach is structured within continuity plans that begin with business impact analysis and risk assessment, and continue with the design and implementation of technology strategies to protect data and enable service recovery.

Conclusion

In a digital environment exposed to disruption, data protection has become a key element in ensuring business continuity and resilience. Data underpins critical processes, applications and services; when data is no longer available, business operations are affected.

Therefore, backup is no longer just a preventive measure. It is an essential capability that ensures the information and systems supporting business operations can be recovered in the event of any incident.

World Backup Day is a timely reminder that protecting data is not only about storing it securely, but about ensuring it can be recovered when the business needs it.

Beyond prevention, backup is an essential capability for recovering the information and systems that support business operations.
