StoneFly + HYCU: Engineered for Secure, Fast Recovery

DR365H is an all-in-one backup and disaster recovery solution that combines StoneFly’s enterprise-grade software-defined storage with HYCU’s agentless, application-aware data protection—designed to secure your data, simplify operations, and ensure fast, predictable recovery.

Built for modern IT environments, DR365H protects virtual machines, physical servers, and cloud workloads without installing agents. Backups are application-consistent, policy-driven, and fully automated—ensuring data integrity without operational overhead.

Security is built into every layer of DR365H. Backups are stored in immutable volumes, air-gapped by design, and isolated from threats using StoneFly’s patented features. Whether recovering a single file or entire systems, DR365H delivers rapid, ransomware-proof recovery when you need it most.

Application-Aware, Agentless, Ransomware-Proof and Always Recoverable

DR365H delivers a fully integrated backup and disaster recovery experience—combining the simplicity of an appliance with the intelligence of agentless, application-aware protection.

How DR365H Delivers End-to-End Backup & Disaster Recovery

The StoneFly DR365H is a fully integrated, turnkey backup and disaster recovery solution that combines StoneFly’s enterprise-grade storage virtualization with HYCU’s agentless, application-aware data protection—all hosted directly on the DR365H appliance. With HYCU running natively on the system, there’s zero latency between the data protection engine and the storage layer, enabling faster backups, instant recovery, and streamlined operations.

Built-in Multi-Layered Ransomware Protection

At the core of DR365H is StoneFly’s patented air-gapped and immutable storage vault, which sets this solution apart:

Air-Gapped vaults can be configured either logically (automated isolation) or physically (isolated hardware), preventing ransomware or unauthorized access from reaching backup copies.

All air-gapped data is also immutable, meaning it cannot be altered, encrypted, or deleted—ensuring the integrity and recoverability of your backups.

This combination of agentless backups, application awareness, immutability, and air-gapping delivers unmatched resilience against ransomware and insider threats.

The DR365H is more than a backup appliance—it’s a fully integrated disaster recovery platform that unifies backup, storage, security, and rapid restore in a single solution. From backup to spin-up, it’s built for speed, simplicity, and peace of mind.

DR365H Key Features:

Enterprise Data Protection & Storage Capabilities

Air-Gapped and Immutable Backups

Patented StoneFly air-gapped vault technology ensures backup data is isolated—physically or logically—and immutable, blocking unauthorized access and ransomware encryption attempts.

Immutable Storage

Backed-up volumes and files are locked from changes for defined retention periods, ensuring compliance and protection from tampering or deletion.

Immutable Snapshots

Schedule point-in-time snapshots that cannot be altered or deleted until expiration, providing reliable recovery rollback options.

Volume Deletion Protection

Prevents accidental or malicious deletion of active or archived volumes with enforced policy-based controls.

Threat Detection and Response

Integrated anomaly detection alerts admins to suspicious behaviors and supports automated remediation workflows for fast containment and recovery.

Secure Connect Fabric

Enables agentless, encrypted backup and recovery for remote and branch office workloads via a secure, policy-driven overlay network.

Hardware-Based Encryption

AES 256-bit encryption at rest and SSL/TLS in transit ensures compliance-grade data security without impacting system performance.

Deduplication

Block-level, inline and post-process deduplication reduces backup storage footprint and optimizes WAN/Cloud bandwidth usage.

Thin Provisioning

Efficiently allocates storage on-demand to reduce unused capacity and improve overall resource utilization.

Direct VM Spin Up

Instantly boot VMs on the DR365H appliance for near-zero RTO and seamless disaster recovery—no need to wait for full restores.

Anti-Ransomware Scanner

Continuously monitors backup data for ransomware signatures and anomalies, enabling early threat detection and faster response.

Sync/Async Replication

Built-in support for synchronous and asynchronous replication across local, remote, and cloud targets for flexible disaster recovery.

Integrated Dual Hardware Controller Appliance (R2)

The R2 appliance integrates dual hardware controllers within a single-node architecture to deliver two isolated environments—one for the HYCU backup server and the other for secure, ransomware-proof target storage. This setup mirrors the experience of running dedicated appliances while minimizing hardware footprint. Each controller operates independently, creating segmented security zones to protect enterprise workloads and data. The result is a high-availability HYCU backup solution that enhances both performance and security in a unified platform.

The secondary controller offers versatile configurations, acting as a recovery module with built-in air-gapped and immutable storage for backup, replication, and archival. It supports up to 64 immediate restore points for rapid recovery, click-to-restore VM capabilities, and automated failover for business continuity. Administrators can also leverage the secondary environment as a secure sandbox for DevOps or backup testing—ensuring clean recoveries without disrupting production systems.
