[pbs-devel] Proxmox Backup Server 2.0 released!

[Martin Maurer]

Hi all,

We are excited to announce the next major release v2.0 of Proxmox Backup Server! This version is based on Debian 11 (codename "Bullseye"), but using the newer Linux kernel 5.11, and including OpenZFS 2.0.

Highlights
- Tape Backup is stable and supported
- Support for OpenID Connect providing Single Sign-On (SSO)
- Full integration of Let's Encrypt/ACME in the front- and backend
- Management of APT repositories via GUI: ability to enable and disable repositories
- Single file-restore support for VMs that use ZFS, or LVM internally - accessible from GUI
- ExtJS JavaScript framework to the latest GPL release 7.0
- Improved Proxmox installer with improved ISO detection, switch_root instead of chroot, zstd compression
- Live-restore feature allows for starting a VM, as soon as the restore starts (with Proxmox VE)
- Countless bugfixes and smaller improvements are included as well, see the full release notes for details.

Thanks to all of you who were testing, bug reporting, and patch submitting. It helps a lot to get all the support and feedback!

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 7.0.

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 on https://forum.proxmox.com/forums/announcements.7/ 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.
