Proxmox Backup Server 2.1: Update provides more convenient management functions

Proxmox Server Solutions has released the Proxmox Backup Server 2.1. The update mainly improves the backup management functions. Like the virtualization platform PVE 7.1, the open source backup software is based on Debian GNU / Linux 11.1 Bullseye with a current Linux kernel 5.13 and OpenZFS 2.1.

In order to prevent the accidental deletion of particularly important backups during clean-up operations, users will be able to provide dedicated protection in the future. A backup marked in this way can only be deleted if the marking has been canceled manually beforehand. Filters that build on each other also allow users to determine how sync and tape backup jobs are processed. Filter options are, for example, backup types (host, VM, container), group membership or regular expressions (Regex).

With the Proxmox Backup Server 2.1, users can also specify exactly how much bandwidth should be available for incoming (backups) or outgoing (restores) network traffic. The settings can also be applied to specific network segments or to specific time periods.

The support of OpenID Connect (OIDC) for single sign-on and 2FA / MFA already introduced with the Proxmox Backup Server 2.0 has been further improved. In the graphical WebGUI there is a new panel for managing the data traffic, some graphs are now also with a higher resolution. Anyone who still works with tape backups will be happy about the new display of the next tape media label.

If problems arise, the new tool proxmox-backup-debug helps with checking datastore files and enables an integrity test of the chunks.

The Proxmox Backup Server enables entire hosts or the virtual machines or containers on a Proxmox VE server or cluster to be backed up and restored using incremental and fully deduplicated backups. With the aim of developing the most secure and modern software possible, the developers decided to write the backup server in Rust in the press release on the new version.

The Proxmox Backup Server 2.1 is freely available as open source software and is under the GNU AGPLv3. An installation image can be found on the Manufacturer’s download page. Proxmox Server Solutions GmbH offers optional enterprise support including technical support from EUR 449 per year and server – the size of the backup memory used and the number of backup clients are unlimited. Just last week the manufacturer released version 7.1 of its Proxmox Virtual Environment.
