Feature Request - Proxmox VE 9.0 / LVM Support

[jpolansky]

With the recent release of the Proxmox VE 9.0 Beta, they added support for snapshots on LVM block storage. You can see the release notes here: https://pve.proxmox.com/wiki/Roadmap#Pr ... 9.0_BETA_1

I am currently trying to get away from VMWare and into Proxmox, but until Veeam is able to take backups of VMs on LVM storage, I am unable to switch. I use fibre channel for my storage, and my only option for fibre channel in Proxmox is LVM.

I tried taking backups of my VMs using Veeam but it failed, and I also opened a support case to see if this was possible. (Case # 07776941)

Is there any plan to support this in the future?

+1 for supporting backing up Proxmox VM's stored on LVMs which is now supported in v9 beta released on July 18th; and it seems they have a very fast beta cycle of ~3 weeks based on the past two major releases. Any eta from Veeam on supporting this? thank you!

Hi,

Our general goal is to support a new product version within 90 days of its general availability date. However, implementing support for new features is a separate topic.

The earliest release vehicle for Proxmox 9 would be our VDP v13 release in Q4 2025. This timeline depends on when Proxmox goes GA and the amount of code changes required, particularly to support new functionality.

Best,
Fabian

Proxmox VE 9.0 is now in Stable release.
Hopefully now veeam will release their official plan to support V9.

I just upgraded my Homelab to Proxmox 9.

Two specific VMs are not backing up:

VM-NAME : Failed to perform backup: Failed to map disks

The other 8 VMs backup fine.
I'm using a local NVME data store on this server...

EDIT: it looks like changing Default (i440fx) from "latest" to "8.2", fixes the issue.

The machine type of V10 does not work.. You should be good to use the 9.2+PVE1.
10 is new for PVE 9, so it looks like this support will need to be added in a future update from veeam.

Hi!

I don't see V10 that you mentioned...

Workaraound:
Liunx VM , change Hardware > Machine from Default(i440fx) to I440fx Version 9.2
it works

[f.neumann]

It‘s within VM->Hardware->Machine->Edit->Advanced->Version.
Having ‚latest‘ selected will result in „Failed to perform backup: failed to map disks“-Error in Veeam 12.3.
Changing to „9.2+PVE1“ or lower seams to “fix” this error for now.

Hello,

afaik Veeam backups work on shared LVM with Promox v8, the only thing whats missing in Proxmox v8 and shared LVMs are snaphots (which are not required for backups).

"Veeam Backup for Proxmox VE does not support backup of VMs that store their disks in the BTRFS and custom storage. All other Proxmox VE storage types are supported."
