The decision about where to store backups of corporate data is no longer a purely technical choice. It involves variables such as cost, regulatory compliance, fault tolerance, and the ability to recover from increasingly sophisticated incidents. 

According to the Report on the Cost of a Data Breach 2024, published by IBM Security.The average global cost of a data breach reached USD 4,88 million in 2024, the highest value recorded in the 19-year history of the study. This data demonstrates that the choice of backup architecture is, first and foremost, a risk management decision.

In recent years, the market has witnessed a significant migration of workloads to hybrid and multicloud environments, which has raised new questions about how to ensure data protection and recoverability in distributed infrastructures. 

In this article, you will understand how each model works, what its real limitations are, and how to define the most appropriate approach for your environment.

What is traditional backup and how does it work?

O traditional backup It is performed on the organization's own physical infrastructure. The data is copied and stored on devices such as dedicated servers and storage systems. NAS (Network Attached Storage), libraries of magnetic tapes or external disks located in the company's own data center or in a co-managed environment.

This model offers direct control over hardware, transfer protocols, and restoration processes. For organizations with high data volumes or limited internet connections, the speed of local restoration represents a concrete advantage: the data is physically close to the environment that needs to be recovered, eliminating dependence on external bandwidth at the critical moment.

However, this architecture has structural limitations that have become more evident with the evolution of the threat landscape. The lack of geographic isolation is one of them: if a ransomware attack or a physical disaster affects the entire local network, backups stored in the same environment can be compromised along with the original data. 

According to research by CrowdStrike78% of organizations suffered at least one ransomware attack in the last year, and backup repositories were a direct target in a large part of these incidents, demonstrating that isolated local protection is no longer sufficient on its own.

What is cloud backup and what are its advantages?

Cloud backup transfers backup copies to infrastructure managed by a service provider, whether it's a public cloud like AWS, Azure, or Google Cloud, or a private or hybrid cloud operated by a specialized partner. Data transmission occurs via an encrypted internet connection, and storage is maintained in geographically distributed data centers, with physical and logical redundancy built into the architecture.

From an operational standpoint, cloud backup eliminates the need to purchase, scale, and maintain dedicated hardware for data protection. Scalability is elastic: the organization pays for and uses only the capacity it needs and can expand it without any physical intervention. This represents a fundamental shift in the economic model, from CapEx (capital expenditure) for OpEx (operating expenses), which facilitates budget predictability and reduces the technological obsolescence cycle.

Modern cloud backup platforms utilize techniques such as perpetual incremental replication, block journaling, and immutable snapshots to ensure that the most recent state of the data is always protected, regardless of when an incident occurs. This ability to perform continuous or near real-time backups reduces the windows of... RPO (Recovery Point Objective) to levels that the traditional model rarely manages to achieve.

Traditional backup vs. cloud backup: what is the impact on RPO and RTO?

The most significant difference between the two models, from a business continuity perspective, lies in the RPO values. (Recovery Point Objective) and RTO (Recovery Time Objective) that each architecture can sustain in practice.

RPO defines the maximum amount of data that an organization is willing to lose in the event of an incident. In environments with scheduled local backup routines, such as a daily backup performed overnight, the RPO can reach 24 hours. This means that, in the event of a failure at 17 PM on a Friday, all data generated since the previous overnight backup could be permanently lost. For financial operations, customer service systems, or e-commerce platforms, this level of exposure is unacceptable.

Cloud backup, when configured with continuous replication or frequent snapshots, can reduce RPO to just a few minutes or even seconds, because data transmission occurs incrementally and constantly, without depending on scheduled execution windows.

RTO, in turn, measures the time required to restore systems and resume normal operation. Traditional solutions often involve manual physical restoration processes, which can result in RTOs of hours or even days. Modern cloud platforms offer automated failover capabilities, where a contingency instance can be activated in minutes, significantly reducing downtime.

According to data from ITIC CorpThe average cost of unplanned downtime in corporate environments can exceed USD 300.000 per hour. When considering that a hardware failure in a local backup environment can paralyze the restoration process for hours, the real cost of a poorly sized model tends to be substantially higher than the investment in a managed cloud solution.

Cloud backup and LGPD compliance: what your company needs to know.

A General Law on Data Protection (LGPD)The regulation, in effect since 2020, establishes clear obligations regarding the storage, processing, and retrieval of personal data. Organizations in the financial, healthcare, and public service sectors face additional layers of regulation, such as Central Bank resolutions, ANS (National Agency for Supplementary Health) standards, and ISO 27001 requirements, which impose specific demands on the geographic location of data, access controls, and audit processes.

In the traditional model, compliance depends entirely on the policies and controls implemented by the organization itself. This offers flexibility, but places the entire responsibility for maintaining controls, documentation, and responding to audits on the internal team, which represents a significant operational burden, especially in companies with small IT teams.

Enterprise-grade cloud backup providers operate under certifications such as ISO 27001, SOC 2 Type II, and PCI DSS, and provide compliance reports, access logs, and contracts with specific data processing clauses. For organizations that are frequently audited or need to demonstrate adherence to the LGPD (Brazilian General Data Protection Law), this structured transparency represents a significant operational gain.

How do you determine which model is best suited for your company?

The choice between traditional backup, cloud backup, or a hybrid architecture should be guided by an objective assessment of four variables: the criticality profile of the data, the RPO and RTO objectives defined by leadership, the volume and rate of change of information, and the regulatory requirements applicable to the sector.

Companies with operations concentrated in a single site, low dependence on digital systems, and a limited connectivity budget can, in some cases, operate with an on-premises solution complemented by periodic offsite replication. Organizations with multiple sites, remote teams, cloud environments, or stringent regulations, however, tend to benefit significantly from a cloud-centric or hybrid strategy, with continuous monitoring, automated recovery testing, and compliance reporting.

The critical point, regardless of the model adopted, is to ensure that the backup strategy is regularly tested. A backup that has never been restored in a controlled environment is not a guarantee—it's an expectation. Periodic recovery tests are the only reliable mechanism to validate that the defined RPO and RTO objectives are, in fact, achievable.

Frequently asked questions about traditional backup and cloud backup.

The choice between local backup and cloud backup generates recurring questions for IT managers and business leaders, especially when the decision involves critical environments, regulatory requirements, and budgets under pressure. 

The questions below address the most common concerns that reach our experts, with objective answers based on best practices and the latest data on the data protection market. 

Is cloud backup safe for sensitive and confidential data?

Yes, provided the provider operates with end-to-end encryption, both in transit and at rest, and possesses internationally recognized security certifications such as ISO 27001 and SOC 2 Type II. Enterprise-level providers also offer granular access control, audit logs, and immutable copies that prevent data alteration or deletion by external agents, including ransomware attacks.

The security of cloud backups depends not only on the provider, but also on the access and authentication policies configured by the organization itself.

What is the difference between cloud backup and cloud storage?

Cloud storage, such as Google Drive or OneDrive, is geared towards accessing and sharing files. It does not guarantee automatic versioning, retention for defined periods, granular system restoration, or compliance with corporate backup policies. 

Cloud backup is a dedicated data protection solution with features such as scheduling, incremental replication, retention policies, recovery testing, and support for defined RPO and RTO. Using cloud storage as a substitute for a backup solution can create a false sense of security.

Does local backup still make sense in 2026?

It makes sense as part of a hybrid architecture, not as a standalone solution. Local storage offers superior restore speeds for large volumes of data, which reduces the RTO in day-to-day operational failures. 

However, without an offsite or cloud replication layer, the environment is exposed to risks that a physical incident or ransomware attack can materialize in minutes. Current market recommendations, consolidated in frameworks such as NIST SP 800-34 and the 3-2-1-1-0 strategy, are that at least one copy of the data should always be outside the primary environment and be immutable.

How do I know which backup strategy is best suited for my company?

The definition begins with the analysis of two indicators: the acceptable RPO for each critical system (how much data the company can lose without compromising operations) and the tolerable RTO (how long the company can be without access to a given system). 

Based on these numbers, it's possible to calculate the necessary backup frequency, the most suitable type of storage, and the real cost of each architecture. Companies with financial systems, ERPs, or customer service platforms generally require RPOs of less than an hour, which already points towards cloud or hybrid solutions with continuous replication. 

Having a company specialized in this assessment reduces the risk of underestimation and misallocation of investments.
