> Support for Proxmox VE:

> Performance:

> Deduplication:
> Periodic backups produce large amounts of duplicate data. The

> Incremental backups:
> Changes between backups are typically low. Reading and sending only

> Data Integrity:

> Compression:
> The ultra fast Zstandard compression is able to compress several

> 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

> Web interface:

>
> 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
