When an organization is hit by ransomware, one of the first things many people rely on is the backup. The expectation is simple: if backups exist, systems should be recoverable.
However, in reality, backups are not always usable when an incident occurs.
Some organizations discover that their backups have been encrypted together with their primary systems. Others have never performed a real restore test. In some cases, the backup data is incomplete, making it impossible to recover critical systems within the required timeframe.
Therefore, having backups is not just about keeping copies of data. Organizations must be confident that they can restore systems and resume business operations after a cyberattack.
Below are five major impacts that can occur if backups fail during a ransomware attack, along with practical ways to address them.
1. Business Operations Can Stop Immediately
If backups cannot be used, the organization may be unable to restore critical systems such as ERP, email, file servers, databases, accounting systems, sales platforms, or customer service systems.
As a result, employees may be unable to work, customers may be unable to access services, and business processes may be disrupted on a large scale.
How to Address and Prevent It
Organizations should start by prioritizing their business-critical systems. This means identifying which systems must be restored first, such as systems related to revenue, customer service, or essential employee operations.
Next, organizations should clearly define their RTO and RPO.
- RTO, or Recovery Time Objective, refers to the maximum amount of time the organization can tolerate system downtime.
- RPO, or Recovery Point Objective, refers to the maximum amount of data the organization can afford to lose, measured backward from the time of the incident.
If these two values have never been defined, recovering from ransomware becomes much more difficult because the organization will not know which systems to restore first or how quickly they need to be recovered.
Checklist
- Are all critical systems covered by backups?
- Has the organization prioritized which systems must be restored first?
- Have RTO and RPO been clearly defined?
- Has the organization ever performed a real restore test?
2. Critical Data May Be Permanently Lost
Ransomware does not only lock files on user devices. In some cases, it may delete data, corrupt files, or encrypt both primary data and backup data.
If backups are stored within the same environment, use the same access privileges, or are not separated from production systems, the organization may suffer permanent loss of critical information.
High-risk data may include customer documents, accounting records, contracts, internal reports, sales data, employee information, and personal data.
How to Address and Prevent It
Organizations should follow the 3-2-1 backup strategy. This means keeping at least three copies of data, storing them on at least two different types of media or systems, and keeping at least one copy separated from the primary environment.
Organizations should also consider using immutable backups. Immutable backups cannot be modified, deleted, or encrypted within a defined retention period, helping reduce the risk of attackers destroying backup data.
Another important step is to separate backup access privileges from the main administrator accounts. If an admin account is compromised, attackers may be able to delete backups immediately if access is not properly separated.
Checklist
- Are backups separated from the primary systems?
- Does the organization have offline backups or immutable backups?
- Do backups use the same administrator accounts as the primary systems?
- Is access to backups limited based on necessity?
3. Recovery Costs Can Increase Significantly
When backups are unusable, organizations may need much more time to recover. They may also need to hire incident response teams, digital forensics specialists, external vendors, or even rebuild systems from scratch.
The cost is not limited to system recovery. It can also include lost revenue, contractual penalties, lost business opportunities, reputational damage, and the cost of communicating with customers, partners, and relevant authorities.
How to Address and Prevent It
Organizations should have an incident response plan that covers situations where backups cannot be used, not only scenarios where backups are ready for recovery.
The plan should clearly define who makes decisions, who coordinates the response, and who is responsible for IT, security, legal, management, and communications. It should also include emergency contact channels that do not rely on internal systems that may be affected by the attack.
In addition, organizations should conduct tabletop exercises to simulate real ransomware scenarios, such as failed backups, system outages, and data leakage. This helps teams understand what actions to take first during a real incident.
Checklist
- Does the organization have an incident response plan for ransomware?
- Is there a backup plan if backups cannot be restored?
- Has the organization conducted real incident response exercises?
- Is there an external incident response team ready to support when needed?
4. The Organization May Be Pressured to Pay the Ransom
If backups cannot be used, the organization has fewer recovery options and may feel pressured to pay the ransom in exchange for data decryption.
However, paying the ransom does not guarantee that all data will be recovered. It also does not guarantee that attackers will not leak the data or return to attack again in the future.
How to Address and Prevent It
Organizations should prepare a decision-making policy in advance for ransom situations. This policy should define how the organization will respond, who has decision-making authority, and which parties must be consulted, such as executives, legal teams, security teams, or external advisors.
Organizations should also preserve logs and key evidence for incident analysis. This includes identifying how the attacker gained access, which accounts were used, what data was accessed, and which systems were affected. This information is essential for decision-making and for planning an accurate recovery strategy.
Checklist
- Does the organization have a policy for handling ransom demands?
- Are logs sufficient for investigation and retrospective analysis?
- Is there a security team or SOC available to support incident analysis?
- Is there a communication plan for executives and legal teams?
5. Customer and Partner Trust May Be Damaged
When systems remain down for a long period, data is lost, or services are disrupted, customers and partners may begin to question the organization’s cybersecurity readiness.
The impact on trust can be more serious than the technical damage itself because it can affect brand reputation, contract renewals, and future business opportunities.
How to Address and Prevent It
Organizations should have a clear crisis communication plan. The plan should define who needs to be informed, when communication should happen, and how messages should be delivered.
The information shared must be accurate, avoid unnecessary panic, and not reveal technical details that could increase risk.
Organizations should also be able to explain their preventive measures and recovery plans. This may include how backups are managed, whether restore tests are performed, whether threat monitoring is in place, and how the organization plans to reduce the risk of recurrence.
Checklist
- Does the organization have a communication plan for cyber incidents?
- Is there a person responsible for communicating with customers and partners?
- Can the organization clearly explain its backup and recovery plan?
- Is there a post-incident report that summarizes the root cause and prevention plan?
How Should Organizations Get Started?
Having backups alone may not be enough. Organizations should verify that their backups are usable, protected from attacks, and capable of restoring critical systems within the timeframe the business can tolerate.
Key actions organizations should start with include:
- Review the backup policy to ensure it covers all critical systems.
- Test restoration regularly, not just confirm that backup jobs are completed.
- Separate backups from primary systems and restrict access privileges.
- Use immutable backups or offline backups to reduce ransomware risk.
- Create an incident response plan for scenarios where backups are unusable.
- Implement security monitoring to detect abnormal behavior before an incident escalates.
What If the Organization is not Ready to Handle This Internally?
For many organizations, designing backup systems, testing restoration, preparing incident response plans, and monitoring ransomware threats require specialized expertise, time, and resources.
If an organization does not yet have an internal security team that can manage all these areas, or if it is not confident that its backups can actually be restored during a ransomware incident, working with external cybersecurity experts can be an effective way to reduce risk.
BMSP helps organizations assess cybersecurity readiness, identify system risks, develop ransomware prevention strategies, and support threat monitoring through a team of Security Operations experts.
BMSP’s services help organizations build a clearer response approach, from preparation before an incident, abnormal behavior detection, and incident analysis, to response planning when a cyber incident occurs.
Responding to ransomware is not only about having backups. Organizations must ensure that backups are secure, recoverable, and supported by a team that can help analyze the situation when an incident happens.
If your organization is not sure whether its backups and ransomware response plan are truly ready, you can consult the BMSP team to assess your readiness and develop a practical risk reduction strategy before a real incident occurs.
Key Takeaways
A backup that exists but cannot be restored may be no different from having no backup at all, especially during a ransomware incident where every minute matters.
Organizations should regularly verify that their backups are secure, separated from primary systems, access-controlled, and truly recoverable.
Ransomware may be increasingly difficult to avoid, but the damage can be reduced if organizations prepare in advance with reliable backups, security monitoring, and incident response planning.
BMSP is ready to be your cybersecurity partner, helping your organization prepare for threats and maintain business continuity even during a crisis.
