Hey folks, Vladan here. If you've followed my blog for any length of time, you know I'm always keeping an eye on backup and recovery solutions that make life easier for virtualization admins — especially those managing VMware vSphere, mixed environments, or even emerging hypervisors like Proxmox VE. NAKIVO Backup & Replication has been a solid, lightweight alternative to the big players for years, with strong agentless support, good performance, and excellent value. Nakivo Backup can be installed on Linux, Windows or compatible NAS device so it is very flexible and adapts to many situations.

Just released on March 10, 2026, NAKIVO Backup & Replication v11.2 brings timely compatibility updates and a security tweak that's increasingly important. This is exactly the kind of incremental release that keeps your jobs running smoothly during upgrades. Let's break down what's new, why it matters for real-world admins, and how it fits into typical VMware/Proxmox setups.

Before we go, let me remind you that you can also use Nakivo to migrate your workloads from VMware to Proxmox. Simply take your backups and do a restore to your new hypervisor.

Full Support for VMware vSphere 9

The headline for most readers here: NAKIVO v11.2 now fully supports VMware vSphere 9 (including vCenter Server 9.0.1.0, ESXi 9.0.1.0, and VDDK 9.0.1.0).If you're planning (or already doing) a vSphere 9 upgrade — especially now that features are bundled under VMware vSphere Foundation (VVF) 9.0 rather than standalone Standard/Enterprise Plus editions — this means no more waiting for backup compatibility or running in partial/limited mode.

(For more on the licensing shift, check my earlier post on VMware vSphere 9 Standard and Enterprise Plus – Not Anymore?.)

Key capabilities that carry over unchanged:

  • Agentless image-based backup and replication — leverages Changed Block Tracking (CBT) for efficient incrementals.
  • Fast, deduplicated, compressed backups — great for reducing storage footprint on repositories.
  • Instant VM recovery, granular file-level, and application-object recovery (e.g., Exchange, SQL items).
  • Built-in DR with VM replication, failover/failback, and Site Recovery orchestration for non-disruptive testing.
  • Ransomware resilience — immutability on supported targets (S3-compatible, cloud object storage like AWS S3, Wasabi, Azure Blob, Backblaze B2; dedup appliances like HPE StoreOnce, NEC HYDRAstor, Dell EMC Data Domain), AES-256 encryption (source, transit, rest), air-gapped options (tape, detached USB/NAS), and pre-recovery malware scanning.

In practice, if your environment is on vSphere 8.x and you're eyeing 9 for the latest security patches, performance tweaks, or new hardware support, you can upgrade VMware first and then point NAKIVO to it without breaking jobs. (NAKIVO was quick to add initial vSphere 9 compatibility back in 11.04 — see my note on vSphere 9.0 Supported by Nakivo 11.04 — and this 11.2 release solidifies full production readiness.)

Proxmox VE 9.0 Full Support + 9.1 Compatibility

NAKIVO continues to invest in Proxmox VE — now with full support for Proxmox VE 9.0 and compatibility for 9.1.For those running Proxmox (often in homelabs, edge sites, or cost-sensitive production — and increasingly as a VMware alternative):

  • Agentless backup/replication at the host level — no guest agents needed.
  • Block-level incrementals via native/propriety change tracking (similar to CBT).
  • Instant recovery of VMs, templates, files, or app objects.
  • Replication for quick DR, plus automated verification with screenshot reports.
  • Same ransomware features: encryption, immutability, air-gapped copies.

This keeps Proxmox users protected during upgrades without workflow changes. If you're using Proxmox alongside VMware (hybrid setups are more common now), NAKIVO's single pane of glass simplifies management — and their Proxmox support has been evolving steadily (e.g., replication and backup-copy jobs added in earlier releases like v11.1).

HPE StoreOnce Enhancements

Added full support for HPE StoreOnce VSA Gen 5 — better integration for deduplication appliances. If your repo is on StoreOnce, expect smoother performance and compatibility in v11.2.OAuth 2.0 for Secure Email NotificationsA smart security-focused addition: OAuth 2.0 support in email settings (replacing deprecated Basic Auth).

This is huge for compliance and modern email providers (Google Workspace, Microsoft 365). No more storing plain passwords for SMTP alerts — use token-based auth instead. It aligns well with broader ransomware resilience strategies, like the malware scanning and immutable backups I've covered in depth before (e.g., in Diving Deep into Nakivo Backup & Replication: Lesser-Known Features…).

Performance & Core Tweaks Under the Hood

The release upgrades the platform to Java SE 24 and latest Spring Framework — expect better overall stability, security patches, and minor performance gains in backup/restore throughput.Combined with existing strengths (LAN-free transfers, network acceleration, global dedup, variable compression, log truncation for SQL/Exchange), backups should stay fast — especially on NAS-based deployments.

Final Thoughts

NAKIVO v11.2 is a “keep you current” release — essential if you're on/going to vSphere 9 or Proxmox 9.x, and the OAuth 2.0 shift is a welcome proactive security move. For admins juggling upgrades, tight budgets, or mixed hypervisors, it ensures continuity without drama. If you're already on NAKIVO, update soon (check helpcenter.nakivo.com for full release notes). New? The 15-day trial lets you test vSphere 9/Proxmox support hands-on.
