VIENNA, Austria – April 15, 2021 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") has today announced the release of Proxmox Backup Server 1.1. The new version is based on Debian Buster 10.9, but using a newer, long-term supported Linux kernel (5.4.106), and including ZFS 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 to back up and restore virtual machines, containers, and physical hosts. The client-server software supports incremental, fully deduplicated backups, and significantly reduces network load, required storage space and, as a result, total infrastructure cost. It seamlessly integrates into the virtualization management platform Proxmox Virtual Environment (Proxmox VE), allowing users to simply add a server as a new storage target.
The new Proxmox tape backup, available as a technology preview in Proxmox Backup Server 1.1, provides an easy way to copy datastore content to tapes. Despite its age, digital magnetic tape continues to provide an easy and economical way for large amounts of data to be archived. Be it for compliance reasons or peace of mind, tape backup makes sense in any effective enterprise backup plan. The existence of WORM (write once read many) tapes, the low cost per unit, and the fast sequential write speeds are all clear benefits of tape based storage.
Proxmox Backup Server supports all Linear Tape-Open generation drives (LTO-4 and later), thus, it includes hardware encryption. Further details of what the Proxmox tape backup system offers are:
With Proxmox Backup Server 1.1, users can now set up Two-Factor Authentication (TFA) which adds another layer of security to the authentication process, making it harder for cybercriminals to access the network and take over accounts. The following second factors are available:
The two-factor authentication can be activated or configured via the GUI, by the users themselves or by a system administrator. TFA is complemented by the existing, token-based authentication for granting access to Proxmox Backup Server resources, for example, when configuring a Proxmox Backup Server storage in a Proxmox VE set up.
Responses from the API of Proxmox Backup Server can get quite large, but can generally be compressed well. By adding support for deflate Content-Encoding, bandwidth utilization, transfer speed, and response times have been improved, especially over bandwidth constricted links.
Downloading a directory from a file-level backup will now produce a compressed ZIP archive, reducing bandwidth and local space required.
Following the massive increase in deployments after the first stable release (1.0), a couple of bugs were reported by the community, which have now been fixed:
Proxmox Backup Server is free and open-source software, published under the GNU Affero General Public License, v3. The downloadable ISO image can be installed on bare-metal. For a production setup, dedicated hardware is recommended. Proxmox Backup Server 1.1 is now available for download at https://www.proxmox.com/downloads
The backup server from Proxmox comes stocked with all the essential management tools, as well as an easy-to-use, web-based user interface. This allows for simple, out-of-the-box management of the server, either through the command line or a standard web browser.
For enterprise users, Proxmox Server Solutions GmbH 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 449 per server, including unlimited backup storage and unlimited backup-clients.
