[pbs-devel] Proxmox Backup Server 3.3 released!

[Thomas Lamprecht <t.lamprecht@proxmox.com>]

Hello all!

We’re excited to share the newest release of Proxmox Backup Server 3.3, packed
with updates and improvements inspired by your valuable input!

This version is based on Debian 12.8 ("Bookworm") but uses the newer Linux
kernel 6.8.12-4 as stable default and kernel 6.11 as opt-in, and ZFS 2.2.6
(with compatibility patches for Kernel 6.11).

Here are some of the highlights

- New push direction for remote synchronization jobs
- Support for removable datastores
- New webhook notification target
- New change detection modes for speeding up file-based host and container
  backups
- Countless improvements for general client and backend usability

As always, we’d love to hear your thoughts. Check out the full release notes
and share your feedback below!

FAQ
Q: Can I upgrade the latest Proxmox Backup Server 2.x to 3.3 with apt??
A: Yes, please follow the upgrade instructions on
   https://pbs.proxmox.com/wiki/index.php/Upgrade_from_2_to_3

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 8.2.

Q: Is Proxmox Backup Server still compatible with older clients or Proxmox VE
   releases?
A: We are actively testing compatibility between all currently supported major
   versions, including the previous version. Full compatibility with even
   older (major) client versions is supported only on a best effort basis.

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.

Best regards
Thomas Lamprecht
