Backup and Rapid Recovery
Enhancing Operational Resilience
Visibility, Management, and Reporting Through a Single Centralized Panel
At the core of Salvador’s rapid recovery capability is its advanced backup technology, designed to capture the entire system without compromise.
This technology creates a complete full-image backup of the system, including the operating system, drivers, data files, and user-specific settings.
Since backups are stored within an air-gapped (offline and isolated) environment, they remain fully protected against cyber threats such as unauthorized access, encryption, or deletion.
Salvador continuously monitors systems and backups 24/7 to instantly detect potential threats. When suspicious activity is identified, the system automatically switches to quarantine mode and prevents malicious content from being backed up. This ensures that infected data cannot compromise backup integrity.
At the same time, real-time notifications sent to both users and administrators enable rapid response and immediate action.
Recovery drills with Salvador can be performed in a seamless, fast, and extremely simple way.
Without shutting down your workstation, you can connect the Salvador unit to a different device and initiate boot directly from the system. This allows recovery scenarios to be tested without impacting the live environment.
Advanced Persistent Threats (APT) are among the most critical cyber risks, capable of infiltrating systems, remaining undetected for long periods, and even targeting backup infrastructures.
Salvador’s air-gapped architecture completely isolates recovery copies during an attack, physically preventing unauthorized access. As a result, even if the system becomes infected, backup data remains securely protected.
The second and third backup copies are secured through a patented offline protection layer and can only be accessed through authorized Salvador software. Additionally, since the disks remain invisible to the operating system, malicious software cannot access or compromise the backups.
Traditional Disaster Recovery (DR) solutions are primarily designed to recover data against physical disasters such as earthquakes, floods, or fires. However, since these systems typically operate in an online environment, they can remain vulnerable to cyberattacks.
Salvador, on the other hand, is specifically designed to provide protection against ransomware attacks and advanced cyber threats such as APT (Advanced Persistent Threats).
Salvador provides fast deployment and centralized management capabilities for distributed environments, enabling easy operation across large-scale infrastructures.

Centralized Backup and Complete Data Visibility
Uninterrupted Data Protection and Minimum Data Loss
Real-Time Monitoring and Automated Verification
OT and ICS environments are critical infrastructures with zero tolerance for downtime. In these environments, data loss or system outages can lead to production losses, operational disruptions, and significant financial damage.
Salvador’s centralized backup platform eliminates the risk of data loss by managing all systems from a single point. All endpoints are continuously monitored, backed up, and verified.
This enables organizations to achieve fast and reliable recovery during potential crisis situations while maintaining uninterrupted operational continuity.
One of the biggest challenges in distributed and multi-site OT environments is the inability to centrally manage and control all systems. The Salvador platform consolidates all OT and ICS systems across different locations into a single centralized management panel.
This enables organizations to:
• Monitor all sites from a single interface
• Centrally manage backup processes
• Analyze the status of each location in real time
As a result, organizations gain complete control and visibility across distributed infrastructures.
The Salvador platform continuously monitors all systems through its real-time monitoring capabilities. Abnormal behavior, unauthorized data changes, or suspicious activities are instantly detected.
Thanks to this early warning mechanism:
• Cyberattacks are identified before they can spread
• Response times are minimized
• Data integrity is preserved
This approach enables organizations to operate with a proactive security model rather than a reactive one.
In industrial environments, data volumes grow rapidly, and traditional solutions often fail to handle this scale efficiently. The Salvador platform operates seamlessly in high-volume data environments through its scalable architecture and SAN/NAS integration capabilities.
With an infrastructure that can scale up to petabyte-level capacity:
• Large data sets are securely stored
• No performance degradation occurs
• The infrastructure can be easily expanded based on operational needs
This makes the platform a future-ready and investment-protected solution.
In large-scale organizations, managing hundreds or even thousands of systems creates a significant operational burden. The Salvador platform simplifies this process through its centralized management and bulk deployment capabilities.
Thanks to its plug-and-play architecture and automation features:
• Systems can be deployed rapidly
• Policies can be applied centrally in bulk
• All processes can be managed from a single panel
This reduces the workload for both IT and OT teams while establishing a standardized, secure, and scalable infrastructure across the organization.
