Proxmox Backup Server 2.0 available

VIENNA, Austria – July 13, 2021 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") has today announced the next major version 2.0 of its new open-source server backup solution. This version is based on Debian 11 “Bullseye”, but using the newer Linux kernel 5.11, and including OpenZFS 2.0. The whole software stack is written in Rust – a modern, fast, and memory-efficient language.

Proxmox Backup Server is an enterprise backup solution, capable of backing up and restoring VMs, containers, and physical hosts. By supporting incremental, fully deduplicated backups, the open-source backup solution significantly reduces network load, required storage space and, as a result, total cost of infrastructure. With the integrated web interface, users can easily manage and monitor all backup tasks from a single pane of glass and quickly recover single files, archives, and entire VMs in case of a disaster.

What's new in Proxmox Backup Server 2.0

• Proxmox Tape Backup: Proxmox tape backup, which was released as a technology preview in Proxmox Backup Server 1.1, is now stable, providing an easy way to copy datastore content to tapes. Digital magnetic tape makes sense in any effective enterprise backup plan, especially for archiving large amounts of data. Proxmox Backup Server supports Linear Tape-Open generation 5 (LTO-5) or later drives (with best-effort support for LTO-4), including support for hardware encryption. The user space tape driver and support for autoloaders (pmtx) are also written in Rust.
• Support for the open protocol standard OpenID Connect, providing Single Sign-On (SSO). It is possible to integrate external authorization servers, either using existing public services or your own identity and access management solution, for example, Keycloak or LemonLDAP::NG.
• HTTP Proxy: Support for setting a HTTP Proxy for package updates and subscription check requests has been added.
• Full integration of Let's Encrypt/ACME in the back and front end, with stand-alone and DNS plugins available. This enables administrators to easily create and deploy valid and trusted certificates for their domains with the Let's Encrypt certificate authority.
• Management of APT repositories via GUI: The new 'Repositories' panel shows an in-depth status report, as well as a list of all configured repositories. The new panel provides an overview of all package repository configurations, warns about potential misconfigurations, and allows users to enable and disable a repository.
• Update of the ExtJS JavaScript framework to the latest GPL release 7.0.
• Improved Proxmox Installer: The Proxmox installer now has improved ISO detection, and can automatically detect HiDPI screens and increase console font and GUI scaling accordingly.
• Single file-restore support for VMs that use ZFS or LVM internally. The unified, single-file restore has been extended to support restoring files from LVM(-thin) volumes and ZFS zpools that are contained within a VM archive. This functionality is accessible from the Proxmox VE GUI.
