¿Qué es la recuperación en la nube?

Cloud backup and disaster recovery are two related but distinct disciplines that work together to help protect your organization’s data and operations.   

Cloud backup is the process of copying data – files, databases, application configurations, and system images – to a remote cloud environment. These copies serve as point-in-time snapshots that you can use to help restore data if the original is lost, corrupted, or compromised. Cloud backup removes the need for physical media like tape or on-site storage arrays and helps give you the flexibility to store data across multiple regions and accounts.   

Recuperación en caso de desastre goes further. Recuperación en caso de desastre is a strategy for restoring not just data, but the applications, infrastructure, and workflows your business depends on. A disaster recovery plan defines how quickly you need to be back online (your RTO) and how much data loss you can tolerate (your RPO). 

When you combine cloud backup with disaster recovery, you get a cloud-based disaster recovery strategy – one that helps store protected copies of your data off-site and provide the automation and tooling needed to recover workloads at scale.  

Por qué es importante la recuperación en la nube

The cost of failing to protect your data has never been higher. Data breaches now cost organizations millions of dollars on average.  

But breach costs are only part of the picture. Unplanned downtime disrupts revenue, erodes customer trust, and triggers regulatory scrutiny. For organizations in regulated industries like financial services, healthcare, and legal, the failure to recover data within defined timeframes can result in fines, litigation, and loss of operating licenses.   

Ransomware has changed the calculus further. Attackers increasingly target backup infrastructure itself, encrypting or destroying recovery data before launching their primary attack. Without a cloud recovery strategy that includes isolated, immutable copies of your data, you risk losing both your production environment and your ability to recover from it.   

Disaster recovery as a service (DRaaS) has emerged as one response to this challenge, helping give organizations the ability to replicate and fail over workloads to a cloud-hosted environment without managing their own disaster recovery infrastructure.  

A well-designed cloud recovery plan helps reduce both the financial and operational impact of unplanned outages – and increasingly, it is a baseline expectation from auditors, regulators, and cyber insurance providers.  

Conclusión:la recuperación ante ataques de ransomware readiness is no longer optional. It is a business requirement.  

Buenas prácticas para la recuperación en la nube

Building an effective cloud recovery strategy requires more than selecting a tool. It demands a structured approach to planning, architecture, and testing. The following best practices help you design a cloud disaster recovery solution that holds up under real-world conditions.   

Siga la regla de copia de seguridad «3-2-1». Maintain at least three copies of your data, stored on two different media types, with one copy off-site in the cloud. This foundational rule helps reduce the risk of a single point of failure wiping out all your recovery options.  

Define los objetivos de RTO y RPO por cada carga de trabajo. Not every workload has the same criticality. Your customer-facing production database may require a five-minute RPO and a 15-minute RTO, while a development environment may tolerate hours of downtime. Tier your workloads accordingly and allocate cloud backup solutions for business continuity based on these tiers.  

Utilice almacenamiento inmutable y aislado físicamente. Air-gapped vaults and immutable backups help prevent ransomware from encrypting or deleting your recovery data.   

Pruebe su plan de recuperación con regularidad.Una copia de seguridad que nunca se ha restaurado es una copia de seguridad en la que no se puede confiar. Programe simulacrosde recuperación operativa drills at least quarterly, validate that your RTO and RPO targets are achievable, and document the results.  

Automatice siempre que sea posible.Los procesos manuales de Backup and Recovery conllevan errores humanos y retrasos. Las soluciones nativas de la nube pueden automatizar las programaciones de Backup and Recovery, las políticas de retención y los flujos de trabajo de Recovery para ayudar a reducir la ventana de exposición. 

Cómo Clumio de Commvault te ayuda a proteger tus datos en la nube

 Clumio de Commvault is built for organizations that run production workloads across AWS and Google Cloud and need cloud disaster recovery that delivers speed, reliability, and security at scale. 

Clumio takes a cloud-native, serverless approach to backup and recovery. There is no infrastructure to deploy or manage—you connect your cloud environments, define your protection policies, and Clumio handles the rest. Backup data is stored in an immutable, air-gapped vault isolated from production, helping protect recovery data even if the primary environment is compromised. 

Clumio supports cloud-native workloads including Amazon S3, DynamoDB, RDS y Aurora, EC2 y EBS, Apache Iceberg en AWS, Amazon Neptune, Amazon DocumentDB, and Google Cloud Storage. Recovery es granular, lo que permite restaurar datos a nivel de objeto, prefijo, depósito, partición, tabla o carga de trabajo, dependiendo del servicio. Clumio Backtrack permite la reversión in situ para Amazon S3 y DynamoDB, mientras que Instant Access te permite consultar los datos de copia de seguridad de S3 sin necesidad de una rehidratación completa. 

For recuperación de ransomware, Clumio ayuda a las organizaciones a restaurar puntos de recuperación limpios mediante flujos de trabajo de recuperación granulares. Clumio también permite la recuperación entre cuentas, entre regiones y entre proyectos, lo que ofrece flexibilidad para restaurar datos en entornos en la nube limpios cuando sea necesario. 

Casos de uso habituales de las soluciones de recuperación ante desastres en la nube

A cloud disaster recovery solution is not a one-size-fits-all tool. The right approach depends on the failure scenarios you need to plan for and the workloads you need to protect.  Here are the most common use cases for cloud disaster recovery.  

Recovery tras un ataque de ransomware. Ransomware attacks increasingly target backup infrastructure itself, making air-gapped cloud disaster recovery solutions a critical layer of defense. Having immutable, air-gapped backups stored outside your primary cloud account can help you restore clean data without paying a ransom.  

Eliminación accidental de datos. A single misapplied script or manual error can wipe out an entire S3 bucket or DynamoDB table. Granular cloud backup lets you recover specific objects, prefixes, or partitions without restoring an entire environment – getting your team back to work in minutes, not days.   

Fallos de infraestructura o de región. Cloud outages are rare but not impossible. Cross-region backup and recovery give you the ability to restore workloads in a different region if your primary region goes down, helping maintain business continuity.  

Requisitos de cumplimiento normativo y auditoría. Regulatory frameworks in financial services, healthcare, and other industries require documented backup and recovery capabilities. Disaster recovery as a service can help satisfy audit requirements by providing automated, policy-driven backup with full reporting and retention controls.  

Entornos de nube multirregional e híbrida.Las organizaciones que operan en múltiples regiones o en configuraciones de nube híbrida necesitan una estrategia unificada de recuperación ante desastres en la nube que abarque todos los entornos sin aumentar la complejidad de la gestión. 

Cloud backup is no longer a nice-to-have – it is a foundational requirement for any organization running workloads in the cloud. The threats are real, the costs of failure are measured in millions, and the regulatory bar continues to rise.  

The good news is that modern cloud-native solutions help make it possible to protect your data, meet your recovery objectives, and stay resilient – without the complexity and overhead of legacy approaches. Whether you are defending against ransomware, recovering from human error, or satisfying an auditor, a well-designed cloud recovery strategy helps put you in control.
