Proxmox 2.3 "Backup Server"

We are pleased to announce version 2.3 of Proxmox Backup Server! It's based on Debian 11.5 (codename Bullseye), uses the newer Linux kernel 5.15 as stable default and kernel 5.19 as opt-in, and includes ZFS 2.1.6. We have expanded the prune job system and you can now limit pruning to namespaces. Tipp: test your planned retention options and backup schedules in advance with our built-in prune-simulator. Ransomware protection: Backup features such as fine-grained access control, data integrity verification, and the possibility to create off-site backups through remote sync and tape backups help planning a ransomware defense strategy and ensure that critical data stays protected. Read details in the documentation. We have included many GUI enhancements and further improved the client and back-end on many parts. Countless bugfixes and smaller improvements are included as well, see the full release notes for details. Official announcement Download Proxmox
