Proxmox Backup Server 3.0 and Mail Gateway 8.0: Updated with New Debian Version

Proxmox Backup Server 3.0 and Mail Gateway 8.0 with new Debian version

Proxmox Server Solutions GmbH has released new versions of Proxmox Backup Server and Mail Gateway, following the release of Proxmox Virtual Environment (VE) 8.0. These three products, which are open source and free to use, have been upgraded to the new Debian GNU/Linux 12 “Bookworm”.

The updated Proxmox base system includes changes such as an updated userland with debian-typical changes, an update to Linux kernel 6.1, and ZFS 2.1.12. Additionally, all products now have a text-based user interface (TUI) for installation ISOs, which can help resolve potential problems with the graphical installer on older or newer hardware.

Proxmox Backup Server 3.0 brings improvements to tape handling. For example, tape backup/restore tasks now appear in the WebGUI’s “Task Summary”, and when restoring individual snapshots, the Backup Server now shows a list of all required tapes in advance. If a tape is missing in the autochanger, the Backup Server will wait until the tape has been inserted instead of aborting.

User accounts with repeated failed login attempts via TFA/TOTP are now blocked if authentication with the second factor fails. This provides an extra layer of security even if an attacker knows a user’s password.

As for the Mail Gateway 8.0, it now uses Apache SpamAssassin 4.0.0 and a PostgreSQL 15.3 database. The Proxmox developers have also optimized some default values for new installations. Any improvements, changes, and potential issues when switching from previous Proxmox versions are clearly documented in the roadmap and wikis for each product.

Both Proxmox Backup Server 3.0 and Mail Gateway 8.0 are available as free open source software. There is also the option to access the Enterprise Repository, which is priced at €495 per year for the Backup Server and €165 per year for the Mail Gateway. Professional support is available for both products, with prices ranging from €990 to €3960 per year for the Backup Server and from €460 to €1650 per year for the Mail Gateway.
