NAKIVO has released Backup & Replication 11.2.2, adding full support for VMware vSphere 9.1, broader operating system coverage for physical machine backups and several fixes for existing backup and replication workflows.
For administrators preparing a vSphere upgrade, compatibility is the main news. Proxmox users also get fixes affecting replication network mapping and Transporter connectivity.
Here is a closer look at what has changed.
Full support for VMware vSphere 9.1
The headline addition in NAKIVO 11.2.2 is full support for VMware vSphere 9.1, extending platform compatibility to environments moving to the newer VMware release. Official release notes.
If a vSphere upgrade is on your schedule, check backup compatibility before starting. Updating the backup platform first gives you an opportunity to verify protection and recovery before changing the underlying infrastructure.
Proxmox: continued support, with fixes that matter
Version 11.2.2 resolves two issues affecting Proxmox environments. Network mapping during replication could fail in certain configurations, while a Proxmox Transporter node could receive an inaccessible IP address.
Both fixes are relevant if you use replication for disaster recovery, where connectivity and the correct destination network are essential to bringing replicated VMs online.
For readers catching up with recent releases, full Proxmox VE 9.2 support arrived in version 11.2.1. It remains available in 11.2.2, alongside the existing backup and recovery functionality. Version 11.2.1 release notes.
We covered those capabilities in more detail in Proxmox VE and NAKIVO Backup & Replication 11.1 – a perfect match.
More operating systems supported for physical backup
Virtualization gets much of the attention, but physical servers and workstations remain part of many backup plans. A single machine running a specialist application can be just as important as an entire group of VMs.
Version 11.2.2 expands physical machine backup support to include:
- Debian 13
- Red Hat Enterprise Linux 10, Rocky Linux 10, Oracle Linux 10 and AlmaLinux 10
- Ubuntu 25.10 and Ubuntu 26.04 LTS
- SUSE Linux Enterprise Server 16
- Windows 10 IoT
- Windows 11 26H1
Bare Metal Recovery also gains support for RAID volumes as recovery targets.
That is a welcome addition for physical recovery planning. Before relying on it, I would still test the recovery media against the intended hardware. Discovering a storage or driver problem during a planned test is far easier to deal with than discovering it while a production server is down.
Physical machine backup receives a substantial compatibility update. Newly supported operating systems include:
- Debian 13
- Red Hat Enterprise Linux 10
- Rocky Linux 10
- Oracle Linux 10
- AlmaLinux 10
- Ubuntu 25.10 and Ubuntu 26.04 LTS
- SUSE Linux Enterprise Server 16
- Windows 10 IoT
- Windows 11 26H1
The release also adds RAID volumes as targets for Bare Metal Recovery, expanding recovery options for physical systems.
These additions will be useful for organisations refreshing physical servers and workstations while keeping them within their existing backup setup.
Updated storage platform compatibility
NAKIVO 11.2.2 adds support for the following storage platform versions:
- HPE StoreOnce VSA Gen4 4.3.13
- HPE StoreOnce VSA Gen5 5.2.0
- QNAP QuTS hero h6.0.0.3500
- QNAP QTS 5.2.9.3499
If you run NAKIVO alongside these platforms, review the supported versions before updating your storage environment.
Buffalo NAS deployment support on Windows and improvements to the NAS subscription licensing interface were introduced in the preceding 11.2.1 release.
Scheduling, licensing and configuration fixes
Several fixes address issues that could interrupt protection or make jobs harder to manage.
The scheduler could start jobs on unexpected days, and jobs linked by schedule could be skipped. Version 11.2.2 addresses both behaviours.
Licensing fixes cover Microsoft 365 shared mailbox backups, file share jobs that could become disabled and installation problems affecting some NAS-only subscription licences.
Other changes resolve cases where:
- Exported product configurations could remain unencrypted.
- A Nutanix AHV disk was not backed up after being re-enabled in a job.
- Tenant alarms were missing from the Master Tenant dashboard.
- Date-range reports showed information only for the latest failure.
For existing customers, these fixes may be just as relevant as the new platform support, particularly if they match an issue already under investigation.
Compatibility notes before updating
There are a few limitations to review before scheduling the upgrade.
ARM v7 installations cannot move to the 11.2 line. NAKIVO also announces that Windows 8 and 8.1 will no longer receive vendor support starting with version 11.3.
A known issue affects configuration imports on multi-tenant installations using PostgreSQL. It can cause empty pages or tenant errors; a fix is available through NAKIVO support.
Administrators using VMware Real-Time Replication should also check the I/O filter instructions. Replacing an unsigned filter with a certified bundle carrying the same version number requires a manual update.
Conclusion
v11.2.2 is a solid maintenance release. The headline items – vSphere 9.1, VCF 9.1 and Proxmox VE 9.1/9.2 – are exactly what customers in mixed or migrating environments need: you can upgrade your hypervisors without waiting for your backup vendor. The broad OS updates for physical machines, clearer NAS licensing and the security fix round it off.
NAKIVO continues to deliver what has always been its strength: frequent, practical updates without product silos or complicated licensing. If you’re evaluating it – especially for Proxmox or for a NAS-based deployment – the 15-day free trial is the easiest way to validate it in your own environment.
