Ransomware Now Targets Backups: Could Your Company Recover Its Data?

For many years, businesses treated backup as a simple safety copy. The logic seemed enough: if something went wrong, the company would restore its files and return to normal operations.

But the threat landscape has changed. Ransomware is no longer aimed only at active data. In more sophisticated attacks, criminals also search for backup systems, administrative credentials, storage repositories, and recovery points.

The objective is simple: prevent the company from recovering without paying the ransom.

This makes backup one of the most critical parts of any cybersecurity and business continuity strategy.

Having a backup does not automatically mean being protected. The real question is: could your company restore its data after an attack?

Ransomware has changed its strategy

Early ransomware attacks were relatively simple: the attacker encrypted local files and demanded payment to provide a recovery key. Today, many attacks follow a broader and more planned approach.

Before encrypting data, criminals may try to understand the company environment, map servers, identify administrative accounts, locate backup systems, and find ways to eliminate recovery capacity.

In other words, the attack is not aimed only at files. It is aimed at business continuity.

When backups are deleted, encrypted, overwritten, or made inaccessible, the company loses its main recovery alternative. In this scenario, downtime can last for days or weeks, directly affecting revenue, operations, customer service, and reputation.

Why traditional backups can fail during an attack

Traditional backups may work well for common failures, such as accidental file deletion, disk failure, or the loss of a device. The problem is that ransomware attacks require a more resilient strategy.

A backup can fail during an incident when:

• it is stored on the same server or network as the original data;
• it uses the same administrative credentials as the production environment;
• it can be deleted or overwritten by any compromised administrator;
• it does not retain previous versions for an adequate period;
• it does not include encryption and access control;
• it is not continuously monitored;
• it has never been tested through a restore process;
• it depends on manual processes or outdated documentation.

Under these conditions, a company may discover too late that a backup existed, but it was not recoverable.

The worst time to discover that a backup does not work is during a crisis.

Backup must be treated as recovery, not just storage

A common mistake is to evaluate backup only by the existence of a copy. The company asks: “Do we have a backup?” But the right question should go further:

• Is the backup running every day?
• Are failures being monitored?
• Are previous versions preserved?
• Is the backup protected against malicious deletion?
• Are backup credentials separated from the main environment?
• Are the data encrypted?
• Is there restore documentation?
• Does the company know how long it would take to resume operations?
• Has the restore process been tested?

Backup is not only about storing data. Backup is an operational recovery strategy.

If the company cannot restore the data when needed, the backup has failed its main purpose.

Immutable backup: an essential layer against ransomware

One of the main responses to the evolution of ransomware is the use of immutable backups.

An immutable backup is a copy protected against modification or deletion during a defined retention period. Even if an attacker gains access to the environment, the goal is to prevent that attacker from deleting or changing recovery points before the configured retention period expires.

This protection matters because many attacks attempt to destroy backups before encrypting production data. If recovery points are protected by immutability, the company increases its chances of recovering information without depending on criminals.

However, immutability should not be treated as a standalone solution. It must be part of a broader strategy that includes access control, credential separation, encryption, proper retention, monitoring, and restore testing.

Separating backup from production reduces risk

Another critical point is the separation between the production environment and the backup environment.

If the same administrative user can access servers, applications, databases, and backups, a compromise of that account can put everything at risk. The attacker does not need to find multiple vulnerabilities. One credential with excessive access may be enough.

A safer strategy should include:

• specific accounts for backup operations;
• the principle of least privilege;
• multi-factor authentication whenever possible;
• separation between production administration and backup administration;
• restricted access to backup repositories;
• logs and auditing of administrative actions;
• external or cloud storage for critical copies.

The smaller the attack surface around backup, the greater the chance of recovery during a real incident.

Cloud backup helps create an external recovery layer

Cloud backup is especially relevant because it allows companies to keep copies outside their physical environment.

If local servers are compromised, if hardware fails, or if the company suffers fire, theft, flood, human error, or ransomware, the business can rely on an external recovery layer.

This external layer is fundamental for business continuity. It reduces dependency on the local environment and allows data to be restored from separate infrastructure.

But it is important to emphasize: sending data to the cloud is not enough. The solution must be properly configured, protected, monitored, and tested.

A cloud backup without monitoring can fail silently. A backup without proper retention may not allow the company to return to a point before the attack. A backup without restore testing can create a false sense of security.

Monitoring separates configured backup from reliable backup

Many companies believe they are protected because someone configured a backup in the past. But backups are not static. They depend on agents, credentials, storage space, connectivity, permissions, retention policies, software versions, and data integrity.

Over time, any of these elements can fail.

A backup job may stop running. A server may be renamed. A password may expire. A volume may grow beyond expectations. A database may no longer be included in the right policy. An agent may become outdated. An alert may not reach anyone.

That is why continuous monitoring is an essential part of the strategy.

Backup monitoring means verifying whether:

• jobs completed successfully;
• the amount of transferred data is consistent;
• errors were identified and handled;
• retention is working;
• restore points are available;
• critical environments are protected;
• alerts are generated when something unexpected happens.

Backup without monitoring creates a false sense of security.

Restore testing: the difference between confidence and proof

Even when backup is configured and monitored, one decisive question remains: can it be restored?

The only way to answer this with confidence is through periodic restore tests.

Restore testing helps validate whether data is intact, procedures are documented, the team knows what to do, and recovery time is aligned with business needs.

These tests may include:

• restoring individual files;
• recovering complete folders;
• restoring databases;
• recovering virtual machines;
• validating Microsoft 365 data;
• recovering critical applications;
• simulating disaster recovery scenarios.

Without testing, there is only expectation. With testing, the company starts to have evidence.

Backup proves its value only when restore works.

SaaS also needs backup

Another point many companies still ignore is the protection of data stored in SaaS platforms.

Services such as Microsoft 365, Google Workspace, CRMs, collaboration tools, financial platforms, and cloud systems reduce the need for local infrastructure, but they do not eliminate the company’s responsibility for its data.

Accidental deletions, configuration errors, compromised accounts, insider threats, synchronization failures, and insufficient retention can still cause the loss of important information.

That is why a backup strategy should consider not only local servers and files, but also corporate data stored in SaaS platforms.

The question is not only where the data is. The question is how it would be recovered if something went wrong.

What a modern ransomware-ready backup strategy should include

A backup strategy prepared for ransomware must combine technology, process, and monitoring.

Among the most important elements are:

• cloud backup to keep copies outside the local environment;
• version retention to recover data from before the attack;
• immutability to protect restore points against deletion or modification;
• encryption of data in transit and at rest;
• strict control of administrative access;
• multi-factor authentication whenever possible;
• separation between production and backup credentials;
• alerts and continuous monitoring of jobs;
• execution and failure reports;
• periodic restore tests;
• documented recovery procedures;
• frequent review of protected data coverage.

This combination helps transform backup into a real resilience strategy.

Could your company recover its data?

This is the question every business leader should ask before an incident happens.

It is not enough to know that a backup exists. The company needs to know whether it is up to date, protected, monitored, and tested.

If a ransomware attack happened today, would your company know which data to restore? How long would it take to resume operations? Would backups be available? Would restore points be intact? Would someone be monitoring the process?

Answering these questions before a crisis can make the difference between a controlled interruption and a serious operational shutdown.

Ransomware now targets backups. Your company must make sure recovery remains possible.
