[pbs-devel] Proxmox Backup Server 2.2 available

[Martin Maurer]

Hi all,

We are excited to announce version 2.2 of our Proxmox Backup Server! 
It's based on Debian 11.3 (codename "Bullseye"), but using the newer 
Linux kernel 5.15, and including ZFS 2.1.4.

We have a new namespace feature which allows you to simplify backup 
management from multiple sources on-premises, remotely, and in the 
cloud, by organizing backups into "namespaces" within a single datastore.

The new “read-only” and “offline” maintenance modes allow for safer 
maintenance work on a datastore.

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 dist-upgrade Proxmox Backup Server 1.1 to 2.x with apt?
A: Please follow the upgrade instructions on 
https://pbs.proxmox.com/wiki/index.php/Upgrade_from_1.1_to_2.x

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 7.2.

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.

As long as the backups stay in the same datastore it's relatively easy,
as that's just moving around folders. For cross datastore you need to use
sync-to-local-remote for now, as otherwise data chunk can be missing.

You could do the following on the CLI, note that it'd be best to enable
the new offline maintenance mode to avoid interfering with the PBS daemons,
as this example ignores locking completely.

# change pwd to datastore root dir, e.g.:
cd /mnt/datastore
# create the namespace "foo" manually (or via gui, which doesn't needs the ns/ prefix)
mkdir -p ns/foo

# ensure folder have correct owners to avoid issues on prune/delete
chown -R backup:backup ns

# move all groups of type vm, ct and host
mv vm ct host ns/foo

# or, move just a single group:
# first create the backup group type in the NS, if not already presen
mkdir ns/foo/vm
chown -R backup:backup ns/foo/vm
# move the group
mv vm/101 ns/foo/vm/

# or a deeper namespace "foo/bar"
mkdir -p ns/foo/ns/bar
chown -R backup:backup ns
