Yes !!! ... this is what were waiting for, in spite of that proxmox
already have pretty good out-of-the-box backup solution, we missed inc
& diff backups ...
After putting very good zfs support (since then every my prox setup has
been based on ) this is (imho) next big big step
So big congrats to the team !!!
Now I will shortly describe my usual cluster setups ... and will have
one question about fitting PBS into it
- my cluster - 3 nodes -> 2 nodes are redundant VM hosts and 3rd node
is quorum and BACKUP one !
Thank to ZFS we actually have quasi inc backup (and the very very fast
one -- snapshot repl etc etc ) This 3rd quorum/bck node has very big
zfs 10 raid as backup repository ...
But ... due to zfs I can protect just one Prox host (standalone) with
other prox backup server very efficiently and the most important
benefits in scenarios above are: (imho)
1. very efficient backup (pve-zsync / storage (cluster) sync etc ...)
2. Every backed-up VM is ready to run ! (on very that backup node ...
after snapshot cloning etc etc ) ... So this could be considered as DR
solution also
So since you are about to develop true and serious backup server (huge
respect :) that can actually replace my 3rd backup node , the question
would be:
Can PBS play quorum role ? If yes, perfect ... I do not need 4th
server , othervise 4th server (as such) is needed in smallest HA
solution ...
or ...
Can PBS "be" host also ? ... than I could install prox-qouroum VM
... etc
Thank you very much in advance

Subject: [PVE-User] Proxmox Backup Server (beta)
Message-ID: <[email protected]>
Content-Type: text/plain; charset=utf-8; format=flowed
We are proud to announce the first beta release of our new Proxmox Backup
Server.
It's an enterprise-class client-server backup software that backups virtual
machines, containers, and physical hosts. It is specially optimized for the
Proxmox Virtual Environment platform and allows you to backup and replicate
your data securely. It provides easy management with a command line and
web-based user interface, and is licensed under the GNU Affero General Public
License v3 (GNU AGPL, v3).
Proxmox Backup Server supports incremental backups, deduplication, compression
and authenticated encryption. Using Rust https://www.rust-lang.org/ as
implementation language guarantees high performance, low resource usage, and a
safe, high quality code base. It features strong encryption done on the client
side. Thus, it?s possible to backup data to not fully trusted targets.
Main Features
Support for Proxmox VE:
The Proxmox Virtual Environment is fully supported and you can easily backup
virtual machines (supporting QEMU dirty bitmaps -
https://www.qemu.org/docs/master/interop/bitmaps.html) and containers.
Performance:
The whole software stack is written in Rust https://www.rust-lang.org/, to
provide high speed and memory efficiency.
Deduplication:
Periodic backups produce large amounts of duplicate data. The deduplication
layer avoids redundancy and minimizes the used storage space.
Incremental backups:
Changes between backups are typically low. Reading and sending only the delta
reduces storage and network impact of backups.
Data Integrity:
The built in SHA-256 https://en.wikipedia.org/wiki/SHA-2 checksum algorithm
assures the accuracy and consistency of your backups.
Remote Sync:
It is possible to efficiently synchronize data to remote sites. Only deltas
containing new data are transferred.
Compression:
The ultra fast Zstandard compression is able to compress several gigabytes of
data per second.
Encryption:
Backups can be encrypted on the client-side using AES-256 in Galois/Counter
Mode (GCM https://en.wikipedia.org/wiki/Galois/Counter_Mode). This
authenticated encryption mode provides very high performance on modern hardware.
Web interface:
Manage Proxmox backups with the integrated web-based user interface.
Open Source:
No secrets. Proxmox Backup Server is free and open-source software. The source
code is licensed under AGPL, v3.
Support:
Enterprise support will be available from Proxmox.
And of course - Backups can be restored!

FAQ
Q: How does this integrate into Proxmox VE?
A: Just add your Proxmox Backup Server storage as new storage backup target to
your Proxmox VE. Make sure that you have at least pve-manager 6.2-9 installed.
Q: What will happen with the existing Proxmox VE backup (vzdump)?
A: You can still use vzdump. The new backup is an additional but very powerful
way to backup and restore your VMs and container.
Q: Can I already backup my other Debian servers (file backup agent)?
A: Yes, just install the Proxmox Backup Client
(https://pbs.proxmox.com/docs/installation.html#install-proxmox-backup-client-on-debian).
Q: Are there already backup agents for other distributions?
A: Not packaged yet, but using a statically linked binary should work in most
cases on modern Linux OS (work in progress).
Q: Is there any recommended server hardware for the Proxmox Backup Server?
A: Use enterprise class server hardware with enough disks for the (big) ZFS
pool holding your backup data. The Backup Server should be in the same
datacenter as your Proxmox VE hosts.
Q: Where can I get more information about coming feature updates?
A: Follow the announcement forum, pbs-devel mailing list
https://lists.proxmox.com/cgi-bin/mailman/listinfo/pbs-devel, and subscribe to
our newsletter https://www.proxmox.com/news.
