Disaster Recovery in Practice: When the Cloud Becomes the Front Line

Disruptions to critical systems can be costly—in reputation, time, and revenue. In a landscape of constant threats, such as ransomware attacks and operational failures, companies need to ensure their data and applications are protected and available. That's where cloud-based Disaster Recovery comes in : a strategy that transforms recovery into minutes, not days.

Unlike traditional models, cloud-based DR offers flexibility, scalability, and automation , allowing companies to activate contingency environments on demand, with costs proportional to usage. This reduces investment in idle infrastructure and ensures operational continuity even in critical scenarios.

Disruption Risk (DR) models: replication vs. backup

There are two main approaches:

Continuous replication: It maintains up-to-date copies of applications and data in real time, allowing immediate activation in case of failure.

Scheduled backup: It generates periodic backups for later restoration, making it ideal for less critical systems.

Flexa Cloud offers hybrid solutions that combine both models, balancing cost and recovery speed according to each client's profile.

Use case: ransomware attack and recovery testing

Imagine a financial services company operating 24/7 that suffers a ransomware attack in the middle of the night. Local servers are encrypted, disrupting access to billing and customer service systems.

Thanks to the cloud-based Disaster Recovery plan implemented by Flexa Cloud , the IT team performs the following steps:

Incident detection: The monitoring system identifies anomalous behavior and alerts the security team.

Isolation of the infected environment: Compromised servers are disconnected from the local network to prevent propagation.

Cloud environment activation: Automatic replication is triggered, and the systems are restored to the Flexa Cloud infrastructure in less than 15 minutes.

Integrity validation: The team performs access and consistency tests on the restored data.

Safe return to operation: With a clean and validated environment, the business can resume its activities without data loss or the need to pay ransom.

Flexa Cloud periodically conducts simulated recovery tests , where the client company validates the end-to-end process. This type of exercise ensures that RTOs and RPOs are met and that the team is prepared for any real incident.
