Title: NAKIVO Backup & Replication v11.2: Ransomware Defense, Real-Time Replication, vSphere 9, and Proxmox VE 9.x Support

Date: April 18, 2026

1. Overview

• NAKIVO announces the general availability of NAKIVO Backup & Replication v11.2, a release focused on fast, reliable, and proactive data protection.
• The update centers on automated real-time replication, expanded compatibility with newer VMware vSphere and Proxmox VE versions, and modern authentication mechanisms to enable faster, safer recovery.
• The release aims to help IT teams shorten recovery times, meet evolving infrastructure needs, and strengthen ransomware resilience without adding complexity to existing workflows.
• The product remains deployed by tens of thousands of organizations across hundreds of countries, reflecting a broad demand for streamlined protection across virtual, physical, cloud, and SaaS environments.

1. Automated Real-Time Replication

• Core capability: an automated real-time replication engine that keeps replica VMs synchronized with production workloads.
• Benefit: failover to a near-current replica within minutes after hardware failures, ransomware events, or human error, reducing downtime and data loss.
• Impact: addresses the critical gap between the last scheduled backup and the moment of failure, which is often exposed in traditional backup strategies.
• Practical outcome: organizations can sustain business continuity with minimal disruption even in high-stakes environments where every minute of downtime carries measurable costs.

1. VMware vSphere 9 and Proxmox VE 9.x Support

• Rationale: keeping backup infrastructure aligned with the latest hypervisor versions is essential for reliability, security, and fast disaster recovery.
• Scope: v11.2 delivers enhanced compatibility for VMware vSphere 9 and Proxmox VE 9.x, ensuring smooth operation alongside ongoing platform upgrades.
• Licensing context: the update positions NAKIVO to align with VMware’s evolving licensing directions, while maintaining robust operational readiness.

3.1 Full VMware vSphere 9 Support

• What’s included: comprehensive, production-ready support for vSphere 9, including vCenter Server 9.0.1.0, ESXi 9.0.1.0, and VDDK 9.0.1.0.
• Maturity: after earlier compatibility releases, v11.2 offers full readiness to upgrade VMware infrastructure with confidence that protection workflows remain stable.
• Capabilities available under vSphere 9:
• Agentless image-based backup and replication using Changed Block Tracking (CBT) for efficient incremental backups
• Instant VM recovery to restore workloads within minutes
• Granular file-level and application-object recovery for Exchange and SQL workloads without full VM restoration
• Built-in disaster recovery orchestration with failover, failback, and non-disruptive testing via Site Recovery
• Ransomware resilience through immutable backups, AES-256 encryption, air-gapped copies, and pre-recovery malware scanning
• Fast, deduplicated, and compressed backups to minimize storage footprint across repositories
• Implication: the VMware upgrade path is supported without introducing new risk to existing backup jobs, enabling smoother transitions for administrators planning vSphere 9 adoption.

3.2 Proxmox VE 9.0 and 9.1 Support

• Status: NAKIVO v11.2 provides full compatibility with Proxmox VE 9.0, with Proxmox VE 9.1 already within scope for future readiness.
• Core benefits for Proxmox users:
• Agentless host-level backup and replication that avoids guest agents and reduces VM overhead
• Block-level incrementals via native change tracking, delivering efficiency comparable to CBT in VMware environments
• Instant VM and file-level recovery for rapid restoration of entire VMs or individual files
• Automated verification with screenshot confirmation to validate recoverability without manual intervention
• Immutable backups on S3-compatible and object storage targets, including AWS S3, Wasabi, Azure Blob, and Backblaze B2
• AES-256 encryption at source, in transit, and at rest, with air-gapped options via tape or detached storage
• Impact: for hybrid environments that combine VMware and Proxmox, a unified management interface provides a single workflow, reducing complexity as infrastructure grows.

1. Ransomware Defense Across the Board

• Architecture-wide protection: ransomware defense is integrated into the core of the solution, not treated as a standalone feature.
• Immutability and coverage: backups can be made immutable across a broad set of targets, including AWS S3, Wasabi, Azure Blob, Backblaze B2, HPE StoreOnce, NEC HYDRAstor, and Dell EMC Data Domain.
• Pre-recovery malware scanning: scans are performed before restoration to catch threats early and prevent reinfection.
• Air-gapped options: offline copies via tape, detached storage, or isolated NAS provide a last line of defense when network-connected copies are compromised.
• Perspective from leadership: the emphasis is on compatibility, security, and consistent performance as virtualization platforms evolve, ensuring a smooth security posture during infrastructure modernization.
• Real-world note: users report rapid recovery times and storage savings through data deduplication, reinforcing the operational value of the platform in ransomware scenarios.

1. OAuth 2.0 Authentication and Related Security Enhancements

• Email notifications: v11.2 introduces native OAuth 2.0 authentication for email alerts, replacing legacy basic authentication used by many providers.
• Security benefit: token-based authentication eliminates stored plain-text credentials, delivering a meaningful compliance and security improvement for regulated environments.
• Platform improvements: updates to HPE StoreOnce with VSA Gen 5, together with Java SE 24 and the latest Spring Framework, contribute to improved deduplication performance, security patches, and overall backup/restore throughput—benefits that compound in high-frequency backup environments.
• Wider impact: these changes reduce credential exposure risk and align notification pathways with modern security standards.

1. Enhanced MSP Direct Connect for Multi-Tenant Management

• Multi-tenant efficiency: the MSP Direct Connect interface has been enhanced to provide single-pane visibility across multiple tenants.
• Operational impact: MSPs can manage larger service portfolios with reduced overhead, faster response times, and simplified governance across diverse customer environments.
• Strategic value: the improvement supports growth of managed service offerings without proportionally expanding administrative burden.

1. Availability and How to Access

• Availability: NAKIVO Backup & Replication v11.2 is available now.
• Access options:
• Free trial: fully featured 15-day trial to evaluate capabilities
• Product datasheet: detailed technical documentation and feature summaries
• Customer success stories: real-world implementations and outcomes from existing users
• Practical takeaway: organizations planning upgrades to VMware vSphere 9, Proxmox VE 9.x, or multi-hypervisor deployments can leverage v11.2 to maintain compatibility and strengthen protection without disruption.
