Hello Proxmox,
Thank you for creating this new product. It looks great. It's also good timing
as I'm getting ready to revamp our backup strategy.
I was planning on doing something like described below, and I'm wondering if
PBS can do this.
We have one Hypervisor (we are very small)
I have two ZFS storage pools.
dpool- for running VM's
bpool- for backing up our VM's
both are SAS attached HDD's.
Right now I use pve-zsync to backup the VM's to bpool on a 15 minute, daily,
weekly, and monthly basis.
I WANT to send the weekly snapshots to an offsite pool. I was going to use zfs
send to do this.
Can PBS backup to our local zfs pool, and then sync to the remote server. If
so, does it use zfs send?
Finally, can I somehow move the snapshots that pve-zsync is currently creating
to PBS? Versus destroying them and starting over again?
Thanks,
Daniel

Subject: [PVE-User] Proxmox Backup Server (beta)
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.
