[pbs-devel] Proxmox Backup Server 3.4 released!

[Thomas Lamprecht]

Hello all!

Thanks to our amazing community, we’re rolling out our newest software
update for Proxmox Backup Server 3.4. Your feedback has been instrumental
in shaping these improvements.

This version is based on Debian 12.10 ("Bookworm") but uses the Linux
kernel 6.8.12-9 as stable default and kernel 6.14 as opt-in, and comes
with ZFS 2.2.7 with compatibility patches for Kernel 6.14.

Here are the highlights

- Optimized performance for Garbage Collection
- Granular backup snapshot selection for sync jobs
- Easier backups of arbitrary Linux hosts with new Static build of CLI client
- Increased throughput for tape backup
- Countless improvements for better performance and usability

You can find all details in the full release notes and we are looking forward to your feedback!

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" that contains a
   statically linked build of the client executable that is not dependent
   on specific versions of the dynamic libraries used, see
   https://pbs.proxmox.com/docs/installation.html#client-installation

Q: What will happen with the existing backup tool (vzdump) in Proxmox VE?
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.
