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.
