[pbs-devel] Proxmox Backup Server 2.3 available

[Martin Maurer <martin@proxmox.com>]

Hi all,

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 - 
https://pbs.proxmox.com/docs/prune-simulator/index.html.

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 on 
https://pbs.proxmox.com/docs/storage.html#ransomware-protection-recovery

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.

A big THANK YOU to our community! We are really grateful for all the 
support and feedback, testing, bug reporting and patch submitting.

FREQUENTLY ASKED QUESTIONS

Q: Can I upgrade Proxmox Backup Server 2.x to 2.3 with GUI (or apt)?
A: Yes

Q: How does this integrate into Proxmox Virtual Environment?
A: Just add a Proxmox Backup Server datastore as a new storage target in 
your Proxmox VE. Make sure that you run the latest Proxmox VE 7.x.

Q: How do I install the proxmox-backup-client on my Debian or Ubuntu server?
A: We provide a "Proxmox Backup Client-only Repository", see 
https://pbs.proxmox.com/docs/installation.html#client-installation

Q: What will happen with the existing backup tool (vzdump) in Proxmox 
Virtual Environment?
A: You can still use vzdump. The new backup is an additional, but very 
powerful way to backup and restore your VMs and containers.

Q: Is there any recommended server hardware for the Proxmox Backup Server?
A: We recommend enterprise-grade server hardware components, with fast 
local SSD/NVMe storage. Access and response times from rotating drives 
will slow down all backup server operations. See 
https://pbs.proxmox.com/docs/installation.html#recommended-server-system-requirements

Q: Can I install Proxmox Backup Server on Debian, in a VM, as LXC or 
alongside with Proxmox VE?
A: Yes, but all this is not the recommended setup (expert use only).

Q: Where can I get more information about upcoming features?
A: Follow the announcement forum and pbs-devel mailing list 
https://lists.proxmox.com/cgi-bin/mailman/listinfo/pbs-devel, and 
subscribe to our newsletter https://www.proxmox.com/news and see 
https://pbs.proxmox.com/wiki/index.php/Roadmap.
