This easy three-copy technique stays companies’ hardest protect in opposition to ransomware and knowledge loss – whilst threats evolve and cloud reliance deepens – says Daniel Pearson, CEO at KnownHost.
Cybercriminals are continually trying to find vulnerabilities to use and knowledge loss will be devastating for companies.
One report estimates that cyber incidents will value the US over $639 billion in 2025, with prices projected to achieve $1.82 trillion by 2028. These figures spotlight the essential significance of sturdy cybersecurity methods to mitigate dangers.
Regardless of being launched in 2009, the 3-2-1 backup rule stays a elementary greatest apply for safeguarding enterprise knowledge. This time-tested technique helps organisations minimise the impression of knowledge loss and get better rapidly from cyber threats. Right here’s how companies can use the 3-2-1 backup rule to guard vital knowledge in an evolving risk panorama.
What’s the 3-2-1 backup rule?
The three-2-1 backup rule is an easy but efficient precept designed to reinforce knowledge safety. Finest practices for sustaining enough backup of knowledge embrace holding three copies of knowledge to make sure redundancy in case of failure. It additionally recommends utilising two completely different storage options to guard in opposition to {hardware} malfunctions and holding one copy offsite to safeguard in opposition to disasters like ransomware assaults and pure disasters.
This methodology has been a long-standing greatest apply in IT safety, offering organisations with resilience in opposition to varied knowledge threats.
Why is the 3-2-1 rule nonetheless related in right now’s cyber risk panorama?
Cyber threats are continually evolving, requiring cybersecurity professionals to maintain up with a barrage of recent threats. Nonetheless, the 3-2-1 backup technique is ready to account for all potential threats by diversifying the best way that knowledge is saved and offering a spread of failsafes.
Whereas cloud companies provide comfort, they aren’t proof against cyberattacks, outages, or misconfigurations. Relying solely on cloud storage will increase the chance of knowledge loss.
Ransomware assaults that concentrate on cloud backups have turn out to be more and more widespread, highlighting main considerations that companies are usually not totally secure from having their knowledge held for ransom. One report discovered that 51% of ransomware assaults had tried to focus on backups, too, highlighting the prevalence of this technique.
By concentrating on backups in a ransomware assault, cyber criminals enhance their possibilities of receiving a ransom, as companies don’t have any accessible backup. A diversified backup technique helps counteract these assaults and ensures that companies are usually not pressured to pay a ransom.
Whereas digital transformation has been revolutionary, there are nonetheless advantages to holding knowledge backed up offline. Trendy cyber threats have gotten more and more refined, so sustaining unchangeable backups which can be bodily disconnected from the web prevents tampering or deletion by attackers.
Frequent backup errors companies make
Even with a backup technique in place, companies usually make these vital errors. One report revealed that in 2024, ransomware attackers obtained over $800 million in funds, revealing the extent of the vulnerabilities companies face.
One widespread error that companies make is storing backups on the identical community. If backups are stored on the identical community as main knowledge, then ransomware can nonetheless encrypt them. This renders the backups ineffective.
Whereas sustaining a separate copy of knowledge offline is helpful for sustaining knowledge safety, that is usually a uncared for a part of knowledge backups, with many companies choosing cloud-only storage. In a single report, 78% of enterprise leaders revealed that they’ve adopted the cloud in most or all areas of their enterprise.
It’s not simply cyberattacks that go away companies in danger. One report discovered that {hardware} failures accounted for 45% of knowledge loss for small companies. An offline backup supplies an additional layer of safety and ensures that companies can mitigate the dangers of cyberattacks or {hardware} failures.
Lastly, an efficient backup restoration process is simply efficient if it really works. Repeatedly testing restoration procedures to make sure that they work is important. Failing to usually take a look at backup processes might result in sudden failures throughout vital incidents.
Easy methods to implement the 3-2-1 rule in a contemporary cybersecurity technique
To successfully apply the 3-2-1 backup rule, companies ought to be certain that their knowledge is saved throughout a number of mediums, corresponding to native storage, cloud suppliers, and offline backups, to scale back danger.
Companies can use AI-powered options to usually preserve backups, monitor for anomalies and forestall cyber threats from compromising knowledge integrity.
Lastly, compliance is one other main issue for companies to think about. Many rules, just like the Common Knowledge Safety Regulation (GDPR) in Europe or the worldwide Fee Card Business Knowledge Safety Customary (PCI DSS) require companies to implement dependable backup and catastrophe restoration methods.
Following the 3-2-1 rule helps show due diligence and minimises legal responsibility within the occasion of a breach.
