FAQ

Q: Can I upgrade the latest Proxmox Backup Server 2.x to 3.2 with apt?
A: Yes, please follow the upgrade instructions on https://pbs.proxmox.com/wiki/index.php/Upgrade_from_2_to_3

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 8.2.

Q: Is Proxmox Backup Server still compatible with older clients or Proxmox VE releases?
A: We are actively testing compatibility between all currently supported major versions, including the previous version. Full compatibility with even older (major) client versions is supported only on a best effort basis.

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 and see https://pbs.proxmox.com/wiki/index.php/Roadmap.

is PVE 8.2 a hard minimum for PBS 3.2.2 ?
If Yes why ?

is PVE 8.2 a hard minimum for PBS 3.2.2 ?

No, Proxmox VE 7 still works fine with Proxmox Backup Server 3.2.
And even Proxmox VE 6, except of course using newer features like namespaces, but the general backup/restore tasks should work fine.

A: Yes, but all this is not the recommended setup (expert use only).

I began to understand why installing PBS on the same physical server as PVE was not a very good idea. I have an issue with a disk containing de backups datastore and I don't know how to replace it without making my PVE crashing...
