Proxmox VE 7.2 with many innovations for backups

Proxmox Server Solutions GmbH from Vienna has released version 7.2 of its Proxmox virtual environment. Proxmox VE is an open source HA and cluster-aware solution for running Linux containers and virtual machines simultaneously. It is based on Debian GNU/Linux and can be administered via a central web interface.

The new 7.2 version is based on Debian GNU/Linux 11.3 “Bullseye”, which Proxmox developers have given Linux kernel 5.15.30. Proxmox VE delivers thin Linux containers through LXC 4.0.12, full virtual machines running under KVM/QEMU 6.2.0. In addition to the classic file systems available under Debian GNU/Linux, the Viennese deliver the modern ZFS 2.1.4 with Proxmox VE 7.2 and use its functions. Like all other components, the distributed storage solution Ceph Pacific 16.2.7 (optional Ceph Octopus 15.2.16 until mid-2022) comes from the open source camp.

Proxmox VE uses note templates to better document backups and make them easier to find. Templates can contain variables (e.g. {{node}} : {{guestname}} - ({{vmid}}), which the system automatically populates with the appropriate values ​​when creating the backup.

When creating a backup process, it is now also possible to use a new hook called “job-init” to run tasks before the actual backup has started – for example starting a backup server. special storage. When restoring, the administrator can overwrite more settings than before with individual values.

Proxmox developers use “perlmod” to import their own Rust code from other Proxmox projects as Perl packages. What seems a bit cumbersome has a practical use, because the Proxmox Backup Server “Next Event Scheduling” code has already been ported to Proxmox VE 7.2 via “perlmod”. The Backup Server module has advanced scheduling and allows for more extensive settings.

Proxmox VE 7.2 is again a little more comfortable than its previous versions. With “proxmox-boot-tool kernel pin” you can specify which Linux kernel should be used once (or permanently) on the next boot. Those who frequently create new Linux containers or full fledged VMs will appreciate the ability to customize the ranges for the setup wizard’s unique VMID suggestions. If the upper value and the lower value are identical, the automatic system does not suggest any value, but always asks for a manual entry.

Individual container volumes or VM hard disks can be made accessible to another guest through the web GUI, the connection point (bus/mount point) can be changed.

All innovations are listed in the Proxmox VE 7.2 release notes. The Proxmox 7.2 virtual environment is now available for free download and can be used at no additional cost. Businesses can book extended enterprise support from 95 euros per year (net) and CPU.
