World Backup Day serves as a reminder of a simple truth: only companies that proactively back up their data are prepared for data loss and theft. As attacks by cybercriminals become ever more frequent and sophisticated, data protection strategy has long since become a key factor in a company’s survival. Yet data backup alone is no longer sufficient today. A backup is not an isolated product, but an essential component of a comprehensive incident response and disaster recovery strategy.
In today’s digital world, system failures not only cost a great deal of money, but often damage a company’s reputation as well. Business processes in virtually every company now depend on IT running smoothly. Unexpected failures can lead to a real disaster if there is no comprehensive data backup solution in place. In the worst-case scenario, the very survival of the business is at risk if operations cannot be resumed quickly enough. The ability to deal with an emergency situation quickly determines the extent of financial losses and damage to reputation. This is precisely why a carefully drawn-up emergency and recovery plan is so important.
One of the most important principles when responding to incidents is an action plan that covers as many scenarios as possible. In addition to classic risks such as power cuts, hardware failures or user errors, highly specialised threats have now emerged. Modern strategies increasingly rely on AI-powered anomaly detection: today’s backup systems are capable of identifying atypical data changes – such as those occurring during the initial stages of ransomware encryption – in real time and raising the alarm before the damage becomes irreversible.
Reliable backups are one of the most important measures a company can take to avoid long-term damage following a data breach. If, for example, the company falls victim to a ransomware attack and all data is encrypted, high-quality backups may mean that the only risk is the loss of a few hours’ or days’ worth of data – depending on the backup frequency.
Modern ransomware variants specifically attempt to identify and encrypt or delete backups. Therefore, simple data backup is no longer sufficient. Companies need immutable backups that cannot be deleted or altered, even if admin accounts are compromised.
The aspect of immutability is particularly crucial today. Technologies such as S3 Object Lock ensure that data is locked in an immutable state for a specified period. Even attackers with administrator rights cannot manipulate or delete these backups – an essential defence against ransomware.
Many companies simply assume that backups exist. The more crucial question, however, is: how quickly can we get back up and running? Two key metrics are central to this:
In practice, it is often the case that whilst backups do exist, the recovery process takes too long. Whilst production stands still and customers wait, enormous financial losses are incurred. Modern strategies therefore classify systems according to their business impact. Not every application requires the same RTO. Technologies such as instant recovery or automated workflows enable business-critical applications to be restored as a priority. World Backup Day is the ideal occasion not only to check that backups exist, but also to honestly assess their speed in an emergency.
Not all backups are the same. The speed of recovery depends on the type of backup:
Data backup is no longer merely a technical decision, but a legal necessity. With the introduction of regulations such as NIS2 and DORA, companies – particularly in critical sectors such as energy, healthcare, finance and IT services – are legally required to demonstrate robust business continuity plans.
A breach of the duty of care regarding data backup can not only result in substantial fines but also entail personal liability for the management. NIS2 explicitly requires evidence of regular backup tests and documented recovery processes. A certified backup strategy therefore also serves as a safeguard against legal risks and protects management from personal consequences.
The frequency should always be guided by the question: How long can the company do without a specific piece of information? The biggest mistake remains the complete absence of backups or their insufficient frequency. Other critical mistakes:
Implementing a well-thought-out data backup system takes time and money, but it is a more than worthwhile investment in an organisation’s resilience. It is at the heart of any incident response strategy.
