VIENNA, Austria – April 10, 2025 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") today announced the release of Proxmox Backup Server version 3.4. Designed to address enterprise data protection needs, this latest version of the open-source backup solution introduces new capabilities that further improve performance and usability.
Highlights in Proxmox Backup Server 3.4
Optimized Performance for Garbage Collection (GC): To increase storage efficiency through deduplication, backup data in Proxmox Backup Server is saved as chunks. In order to free up storage space after backup snapshots have been deleted, a garbage collection (GC) process identifies and cleans up unreferenced backup data chunks. This version 3.4 optimizes the GC mechanism and integrates a cache to reduce the number of expensive file metadata updates. While this enhancement increases memory usage, it substantially reduces execution time, resulting in faster and more efficient garbage collection. The caching mechanism can be fine-tuned on a per-datastore basis.
Granular backup snapshot selection for sync jobs: Offsite backups are of great interest for data security and therefore Proxmox Backup Server provides sync jobs to push or pull backup snapshots to and from remote Proxmox Backup Server instances. Group filters already allow the selection of which backup groups should be synchronized. In this latest version, the selection functionality has been extended to allow exclusive synchronization of encrypted or verified backup snapshots.
Static build of Proxmox Backup client: While Proxmox Backup Server is tightly integrated with Proxmox VE, its command-line client can also be used outside of Proxmox VE. A new statically-linked binary of the command-line client makes it easier to create file-level backups of arbitrary Linux hosts.
Increased throughput for tape backup: Since version 3.4, Proxmox Backup Server now allows to increase the number of worker threads when reading chunks during tape backup, which can significantly increase the throughput in certain setups.
Latest versions of open-source technologies: This version is based on Debian 12.10 (“Bookworm”), but uses a newer Linux kernel 6.8.12-9 and includes ZFS 2.2.7 (with compatibility patches for Kernel 6.14). While the kernel 6.8.12-9 is the stable default, Linux kernel 6.14 can optionally be installed for better support of the latest hardware.
Proxmox Backup Server seamlessly integrates into Proxmox Virtual Environment—users just need to add a datastore of Proxmox Backup Server as a new storage backup target to Proxmox VE.
Availability
Proxmox Backup Server 3.4 is now available for download. Users can either update their version of the solution or install the ISO image on bare-metal using the Installation Wizard. Distribution upgrades from older versions of Proxmox Backup Server are possible via APT. Optionally, Proxmox Backup Server can be installed on top of Debian.
License: Proxmox Backup Server is free and open-source software, published under the GNU AGPLv3.
Enterprise Support: For enterprise users, Proxmox Server Solutions offers a subscription-based support model, which provides access to the extensively tested Enterprise Repository, with regular updates via the web interface, as well as technical support on a subscription basis. Prices start at EUR 540 per server, including unlimited backup storage and unlimited backup-clients.

VIENNA, Austria – April 09, 2025 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") today released version 8.4 of its server virtualization management platform, Proxmox Virtual Environment. This version comes with a range of improvements and new features.
Highlights in Proxmox VE 8.4
Live migration with mediated devices: Mediated devices allow physical hardware resources to be partitioned into multiple virtual devices. It is now possible to migrate running virtual machines (VMs) which have mediated devices such as NVIDIA vGPU in use. Within a cluster, live migration to another node is possible if hardware and driver support for live migration is equally available on the target node. An available platform with support for live migration is NVIDIA vGPU. Additionally, the new ‘pve-nvidia-vgpu-helper’ tool simplifies the setup of NVIDIA vGPU drivers.
API for third-party backup solutions: Proxmox VE now provides an API simplifying the development of plugins by external backup solution providers. Third party backup solutions can now directly implement backup and restore functionalities in Proxmox VE, and make use of advanced features. Third-party backup providers can implement a plugin that is fully integrated in the backup stack and in the web interface of Proxmox VE. This gives third-party backup solutions the opportunity to enhance the efficiency, reliability, and manageability of their backup and restore features in Proxmox VE.
Virtiofs directory passthrough: Version 8.4 offers the functionality to share files and directories directly between a host and the VMs running on that host. This is achieved through the use of virtiofs, which allows VM guests to access host files and directories without the overhead of a network file system. Modern Linux guests support virtiofs out of the box while Windows guests need additional software to use this feature.
Latest versions of open-source technologies: Proxmox VE 8.4 is based on Debian 12.10 (“Bookworm”), but uses the Linux kernel 6.8.12 as stable default and the newer kernel 6.14 as opt-in. This version of Proxmox VE includes updates to the latest versions of leading open-source technologies for virtual environments like QEMU 9.2.0, LXC 6.0.0, ZFS 2.2.7 with compatibility patches for kernel 6.14, and Ceph Squid 19.2.1 as stable option.
Further enhancements include more robust backup fleecing, improvements in the software-defined networking (SDN) stack, and additional options in the ISO installer.
Availability
Proxmox VE 8.4 is now available for download. The ISO image contains the complete feature-set and can be installed on bare-metal. Distribution upgrades from older versions of Proxmox VE are possible with apt. It’s also possible to install Proxmox VE 8.4 on top of Debian. Proxmox Virtual Environment is free and open-source software, published under the GNU Affero General Public License, v3.
