Discover how continuous backup models can minimize data loss against advanced ransomware
In an era where ransomware attacks are becoming more sophisticated, organizations across the EU face increasing pressure to maintain operational resilience. Traditional scheduled backups, once a staple for data protection, are proving insufficient against threats that exploit gaps in coverage. With NIS2 directives emphasizing low recovery point objectives (RPO) to ensure minimal downtime, IT managers and CISOs must adapt to models that offer near-real-time protection. This shift is particularly critical for endpoints, where attackers often evade detection through devices.
The urgency stems from recent trends highlighted in expert discussions and reports. Ransomware operators are employing evasion techniques like living-off-the-land (LOTL) and targeting unsupported devices to bypass endpoint detection and response (EDR) systems. For businesses in regulated sectors, failing to address these risks can lead to significant fines, loss of cyber insurance coverage, and prolonged outages. Continuous backup ransomware strategies provide a practical way to mitigate these issues by reducing RPO with continuous models, aligning with EU data sovereignty requirements.
As we delve into 2026, the focus on EU endpoint protection grows, driven by compliance needs under GDPR and NIS2. Implementing robust, automated systems not only safeguards data but also delivers audit-ready evidence of recoverability, helping organizations demonstrate due diligence to regulators and insurers.
Ransomware Tactics in 2025
Ransomware threats are evolving rapidly, with attackers prioritizing speed and stealth to maximize impact. According to recent analyses, groups are increasingly using AI-driven targeting and double or triple extortion methods, where they not only encrypt data but also threaten to leak it or launch denial-of-service attacks. A key trend involves evading EDR by pivoting through unmonitored devices, such as IoT endpoints or legacy systems, allowing initial access without triggering alerts.
In the EU context, these tactics exploit gaps in traditional defenses, leading to higher downtime costs—often exceeding €10,000 per minute for critical sectors like healthcare or finance. Reports from ENISA highlight the rise of ransomware-as-a-service (RaaS) models, enabling less skilled actors to deploy advanced payloads. This surge underscores the need for proactive measures, as attacks can compromise systems in under 30 minutes, far outpacing scheduled backup cycles.
Businesses must recognize the operational chaos from failed restores: lost productivity, regulatory scrutiny, and potential board liability. By understanding these tactics, IT leaders can prioritize strategies that close vulnerability windows and ensure continuity.
Continuous vs Traditional Backups
Traditional backups, typically run on nightly or weekly schedules, leave organizations exposed during the intervals between captures. If an attack occurs mid-day, hours of data could be lost, resulting in an RPO of several hours or more. This model relies on predictable windows, which attackers can timestamp and exploit, especially in environments with high data velocity.
In contrast, continuous backup models capture changes in near real-time, often every 15-60 minutes through filesystem-level tracking and automated snapshots. This approach drastically reduces RPO with continuous models, limiting potential data loss to minutes rather than hours. For EU-based operations, this aligns with NIS2's emphasis on uptime and resilience, avoiding the pitfalls of US hyperscaler dependencies that might compromise data sovereignty.
The shift offers practical benefits, such as no scheduled downtime and maintained system performance. While traditional methods suffice for low-change environments, continuous models excel in dynamic setups like Microsoft 365 or endpoints, providing immutable copies that resist tampering.
Implementation for Endpoints
Endpoints remain a prime entry point for ransomware, making targeted implementation essential. Start by assessing your environment: identify critical devices, such as laptops and servers, and map data flows to pinpoint high-risk areas. Integrate change-tracking tools that monitor file modifications in real-time, replicating data to secure, EU-only storage locations like those in the Netherlands or Germany.
For effective EU endpoint protection, configure air-gapped or immutable repositories to prevent encryption propagation. This setup ensures that even if an endpoint is compromised, recovery points remain intact. Testing is crucial—conduct quarterly simulations to verify RTO and RPO targets, generating logs for audit compliance under ISO 27001 or NEN 7510.
Partnering with managed services can streamline this, offering expertise in endpoint detection without vendor lock-in. For more on securing devices, explore our endpoint backup solutions tailored for regulated industries.
Retention Automation
Automating retention policies is key to managing the data volume in continuous models. Set rules based on compliance needs, such as GDPR's data minimization principles, where older snapshots are aged off after predefined periods—e.g., 30 days for operational data or longer for archival.
Use intelligent automation to classify data by criticality, applying tiered retention: short-term for endpoints and extended for core workloads. This not only optimizes storage but also ensures traceability, with automated logs providing evidence for NIS2 audits. Avoid manual interventions that introduce errors; instead, leverage scripts that enforce write-once-read-many (WORM) standards for immutability.
In practice, this reduces administrative overhead while maintaining cyber resilience, allowing teams to focus on threat monitoring rather than policy enforcement.
Cost Offsets
While continuous models require more storage and bandwidth upfront, several factors offset these expenses. Reduced downtime translates to lower opportunity costs—organizations avoid the millions in losses from extended outages. Additionally, meeting NIS2 and cyber insurance requirements can lower premiums, as provable low RPO demonstrates robust controls.
Efficiency gains include eliminating backup windows, enabling 24/7 operations without performance dips. For EU firms, using sovereign storage avoids hidden fees from non-compliant providers. Over time, automation and scalable solutions, like those for Google Workspace, further amortize costs through predictable SLAs.

Conclusion and Next Steps
As ransomware tactics advance into 2025, adopting continuous backup ransomware approaches is essential for minimizing risks and ensuring compliance. By reducing RPO with continuous models, businesses can achieve faster recoveries, protect endpoints, and maintain EU data sovereignty—ultimately safeguarding against fines, reputational damage, and insurability challenges.

Frequently asked questions
What are the main ransomware tactics expected in 2025? +
Ransomware in 2025 will likely focus on evasion through unmonitored devices and in-memory execution to bypass EDR. Attackers are shifting to RaaS for broader reach, incorporating AI for targeted extortion. This increases the speed of compromises, often under 30 minutes. Organizations need near-real-time defenses to counter these. Compliance frameworks like NIS2 stress the importance of low RPO to limit impact.
How does continuous backup reduce RPO compared to traditional methods? +
Continuous backup captures data changes frequently, dropping RPO from hours to minutes via automated snapshots. Traditional schedules leave gaps exploitable by attackers. This model uses change-tracking for efficiency without disrupting operations. It provides immutable copies for reliable restores. For EU endpoints, it ensures sovereignty and audit-proof recovery evidence.
Why is EU endpoint protection critical under NIS2? +
NIS2 mandates robust continuity measures, including low RPO for critical sectors to avoid downtime. Endpoints are vulnerable to evasion tactics, risking data breaches. EU-focused protection emphasizes sovereign storage to comply with GDPR. It helps demonstrate duty of care to auditors and insurers. Failing this can lead to fines and operational halts.
