The Cloud alone is not enough

When One Backup Isn’t Enough

In recent years, the spread of cloud technology has changed the way we manage and store data.

Many believe that simply “having everything in the cloud” means being safe. But that’s not the case.

The cloud sure offers flexibility, but it doesn’t replace a structured backup strategy. Human error, hardware failures or cyberattacks can compromise even what seems protected.

And when that happens, the difference between a temporary loss and irreversible damage is made by the backups themselves.

Why You Need (at Least) Three Copies

From Risk to Reasoning

Doing a backup doesn’t simply mean “saving a copy”.

It means designing a protection system capable of responding to different risk scenarios.

From this logic comes the 3-2-1 rule:

  • 3 copies of the data,
  • 2 different media,
  • 1 off-site copy, away from the main system.

A simple principle, but one that comes from careful analysis: it doesn’t start from how many copies to make, but from what kind of loss we want to prevent.

Understanding how critical data is, how much it costs to lose it, and how long it takes to restore it: that’s how a truly effective strategy takes shape.

Beyond the 3-2-1 Rule

New Measures for New Challenges

The context has changed. Today, ransomware also targets backup repositories, making the safety copies themselves vulnerable.

That’s why modern best practices evolve into the 3-2-1-1-0 model, which adds:

  • +1 immutable or air-gapped copy, isolated and unmodifiable;
  • 0 errors in recovery tests, because every backup must be verified regularly.

Having copies isn’t enough: you need reliable, isolated, and tested copies.

Only then can we talk about true resilience.

The Gap Between Theory and Reality

A Backup That Doesn’t Work Isn’t a Backup

Many backups aren’t tested, or it’s discovered too late that they’re corrupted or inaccessible.

In Italy, nearly one in three companies has experienced a temporary data loss without being able to immediately restore the copies.

The good news? In most cases, data was recovered.
The bad news? Only after complex and costly interventions.

The problem isn’t having a backup, but knowing if it will really work when needed.

How to Design an Effective Backup Strategy

From Technical Plan to Prevention Culture

A solid strategy starts with a simple question: How valuable is my data to my operations?

From there, every decision becomes clearer:

  • Analyze risks to understand which scenarios to prevent;
  • Set priorities by distinguishing critical data from marginal data;
  • Diversify storage media by combining cloud and local storage;
  • Automate processes, but also test them regularly;
  • Monitor and update, because backup effectiveness changes over time.

Backup, after all, isn’t just a technical measure: it’s a strategy for operational continuity.

It requires planning, awareness and a company culture that views data as an asset to be protected over time.

How to Design an Effective Backup Strategy

From Technical Plan to Prevention Culture

Technologies change, but the principle remains the same: the difference isn’t the number of copies, but their reliability.

A good backup system doesn’t happen by chance: it comes from a clear understanding of risk and the recognition that data is a strategic asset.
It takes planning, method and, above all, a culture of prevention, one that anticipates problems instead of reacting to them.

Only by understanding the real impact that data loss would have on operations can you build protection that’s both effective and sustainable.
Technologies, automation, and regular testing are valuable tools, but they only work when included in a broader strategy of continuity and resilience.

Because a backup isn’t just an archive: it’s what allows a business to stop without losing itself, and to restart, when needed, from the right point.
