v12 Detection Capability Review: Separation of Detection and Response

During the v12 era, Veeam's malware detection primarily relied on two mechanisms:

• Inline Entropy Scan - Real-time analysis of data block entropy changes during backup to detect encryption behavior
• Index Scan - Analysis of abnormal behavior patterns through file system indexing

The characteristic of these two features was that detection was separate from handling - the system could detect threats in real-time, but the response process required manual intervention. In practical use of v12, this mechanism had several clear limitations:

• Low response automation: After detecting suspicious activity, it mainly relied on administrators to handle it manually
• Limited platform support: Detection capabilities were primarily focused on Windows environments
• Insufficient depth analysis: Lacked further threat analysis capabilities after detecting threats

I believe v13 shows substantial progress in this detection capability, beginning the evolution from "detection" to "intelligent response."

What’s New in Veeam v13 Malware Detection

In VBR v13, malware detection is now an integral part of every backup and recovery workflow.

Key Enhancements Include:

• Real-time malware scanning during backup and restore operations.

• Integration with antivirus and EDR tools for automated threat analysis.

• Anomaly detection that flags unusual changes in data patterns.

• Centralized reporting dashboard to monitor all alerts from one console.

V13 Active Response Mechanism: From Detection to Automatic Protection

Proactive investigation: Enhanced threat verification methods

The most important improvement in v13 is the introduction of active backup scanning mechanism. The core concept of this feature is: once suspicious activity is detected during backup, the system immediately triggers more in-depth signature scanning rather than waiting for users to make additional manual judgments.

Software settings:

1. Open the VBR console, go to the top-left Hamburger menu → Malware Detection Setting
2. In the original Signature Detection settings, v13 adds new Proactive investigation options:

The first checkbox enables the active scanning mechanism, while the second option provides further processing, allowing the system to automatically resolve malware incidents based on scan results.

Actual usage effects:

In a simulated ransomware attack test environment, when backup jobs detected large-scale file encryption:

• v12 detected malware: Marked backup as Suspicious, sent alerts, waited for administrator handling
• v13 detected malware: Immediately triggered signature scanning, after confirming threats directly marked as Infected or if no threat was found, re-marked as Clean.

During the v12 era, I frequently heard from customers who discovered Veeam reporting backup archives as Suspicious status but didn't know how to proceed or what was happening. Now with v13's options, we can immediately trigger detection through Veeam without waiting, truly identifying whether problems exist.

Cross-Platform Unified Protection: Linux and Cloud Environments Are No Longer Forgotten Corners

Comprehensive Support for Linux Environments

Another breakthrough in v13 is the full coverage of malware detection capabilities on the Linux platform, which I consider an important part of comprehensive Linux support.

Linux Detection Capabilities:

1. Suspicious file system activity analysis - Same detection logic as the Windows platform
2. Veeam Threat Hunter scanning - Signature-based malware detection
3. YARA rule support - Custom threat detection rules

Key Configuration Points for Practical Use:

For malware detection in Linux environments, pay attention to several special configurations:

1. File system selection: Special characteristics of certain file systems (like Btrfs, ZFS) may affect detection accuracy
2. Permission management: Ensure backup agents have sufficient permissions to read all files requiring detection
3. Performance impact: In resource-constrained Linux environments, detection frequency adjustments may be necessary

Specific Operational Steps:

For agent-based Linux backups, malware detection configuration is basically consistent with Windows environments. It's primarily configured globally through the VBR console's Malware Detection settings, then enabled in specific backup jobs.

Security Protection for Cloud Backups

As more users adopt public cloud, cloud environment security becomes crucial. v13 extends malware detection capabilities to cloud backups:

Supported Cloud Platforms:

• Veeam Backup for Microsoft Azure
• Veeam Backup for AWS
• Veeam Backup for Google Cloud

Usage and configuration, including supported capabilities, are essentially identical to Linux and won't be repeated here.

Antivirus Integration for Linux Mount Servers

v13 supports Linux Server as a Mount Server - this is a fully functional Mount Server. The Secure Restore and Security Scan capabilities available on Windows Mount Servers have been extended to Linux Mount Servers, with equal support for Veeam Threat Hunter signature scanning:

Announced Supported Antivirus Solutions for Linux Versions:

• ClamAV - Open source and free, suitable for budget-conscious environments
• ESET - Commercial solution with strong detection capabilities
• Sophos - Enterprise-grade protection with a user-friendly management interface

Configuration Example:

Using ClamAV as an example, you need to install ClamAV on the Linux mount server, then select the appropriate Linux server in the VBR console's Backup Infrastructure → Mount Servers. During use, both scan backup and Secure restore can call the antivirus software for scanning.

Summary and Recommendations

v13's malware detection capabilities represent a qualitative leap from passive detection to active protection. Several recommendations for actual deployment:

• Gradual implementation: First, validate all new features in test environments before gradually rolling out to production
• Performance monitoring: Closely monitor the impact of new features on backup performance, making adjustments when necessary
• Strategy optimization: Customize detection strategies according to business characteristics, avoiding one-size-fits-all configurations
• Regular drills: Conduct regular malware detection drills to ensure response process effectiveness

These improvements in v13 show us the new positioning of backup systems in overall security architecture - no longer just passive data protectors, but active participants in security defenses. In practical use, proper configuration of these features can significantly enhance an organization's ability to counter modern threats like ransomware attacks.

The Veeam Backup & Replication v13 Malware Detection feature marks a major leap in data protection and cyber resilience.

By combining real-time malware scanning, immutable backups, and AI-powered anomaly detection, Veeam v13 provides the strongest defense yet against ransomware and data corruption.

Stay ahead of cyber threats — upgrade to VBR v13 and protect your backups with confidence.

An Alternative Method to Defend Against Ransomware – Advanced Data Protection Strategies

Introduction

Ransomware remains one of the biggest cybersecurity threats to businesses today. Even organizations with strong firewalls and antivirus software are not immune.

To ensure full resilience, IT administrators must explore alternative methods to defend against ransomware, going beyond traditional endpoint protection to secure data backups, isolate networks, and strengthen recovery plans.

1. The Rising Threat of Ransomware

According to Cybersecurity Ventures, ransomware attacks are expected to cost businesses over $265 billion annually by 2031. Attackers target backups, encrypt data, and demand payment, leaving companies helpless without recovery options.

Traditional defenses (antivirus, intrusion detection) are no longer enough — you need a layered, backup-driven defense strategy.

2. Alternative Ransomware Defense: Immutable Backups

Immutable backups are the backbone of a modern ransomware protection plan. These backups cannot be modified or deleted, even by administrators.

Best practices:

• Store critical backups in immutable storage (e.g., Veeam Hardened Repositories or cloud object storage).

• Use air-gapped or offline backup copies.

• Test recovery regularly to ensure data integrity.

3. Offline Storage

Today, I want to share an unconventional data storage method with everyone: using a rotating system of external hard drives for backup storage. This approach is quite creative and rarely used by administrators. Typically, such rotation methods are more common with optical discs and tapes, and are rarely used with external hard drives. It's important to note that this method isn't a foolproof solution that lets you rest easy; it's more of an unconventional workaround for using offline drives.

Scenario and Requirements:

- A portable hard drive enclosure that allows for easy drive swapping—the faster, the better. Generally, interfaces like USB 3, USB-C, or eSATA are good choices, with USB 3 and USB-C being more universal.

- Multiple high-capacity mechanical hard drives, preferably 7200 RPM SATA drives, which are usually compatible with these portable enclosures.

- Backup data is written to each drive in rotation based on a set cycle, and the backup administrator removes the drives periodically for offline storage.

Achieved Outcomes:

- As long as the data hasn't been tampered with or encrypted before going offline, the data on the drive is secure once offline.

- The backup data on each drive is self-contained and doesn't depend on other drives.

- Each drive contains its own metadata configuration file for reading information during data usage.

- Compared to tapes, this method has advantages: data usage and restoration are more straightforward.

4. Network Isolation and Zero Trust Architecture

Prevent ransomware from spreading by implementing Zero Trust principles:

• Limit network access with role-based security.

• Segment networks to isolate critical workloads.

• Disable unnecessary protocols like SMB and RDP.

📌 Refer to CISA’s Zero Trust Maturity Model for detailed recommendations.

5. Leverage Backup Software with Built-in Security

Tools like Veeam Backup & Replication or Vinchin Backup & Recovery offer ransomware defense through:

• Immutable repositories

• Encrypted backups

• Multi-factor authentication for console access

• Built-in anomaly detection

Conclusion

The best way to defend against ransomware isn’t just prevention—it’s resilient recovery. By combining immutable backups, network isolation, and layered protection, organizations can guarantee data safety even after an attack.

The future of cybersecurity depends on proactive data protection — make sure your backup and recovery strategies are ready.
