Backing Up Proxmox with Veeam

[MeCJay12]

Hello! I swear that I've done this before but for some reason on my new Proxmox 8.1.4 system I'm having trouble installing Veeam and backing up the OS. I first tried to install Veeam like I normally do on Linux systems (command below) but when I ran a backup I get the error

Veeam snapshot kernel module not found

I tried unstalling the veeam package and reinstalling with the veeam-nosnap package and now I'm getting

Insufficient free space for a snapshot in a volume group: pve

Is anyone out there backing up Proxmox with Veeam that can point me in the right direction? I use Veeam to backup everything else so I'm hoping to not make a special backup system just for Proxmox.

wget https://download2.veeam.com/veeam-release-deb_1.0.8_amd64.deb && sudo dpkg -i ./veeam-* && sudo apt-get -y update && sudo apt-get -y install veeam cifs-utils && sudo rm veeam-release* && sudo apt -y upgrade && sudo veeam

you only want to backup OS but NOT VMs, correct ?

then for veeam agent should apply what applies for debian 12 bookworm

for backing up VMs, veeam is not ready for primetime yet. but it's probably on the way....

Yes, to backup the host itself. I have used Veeam on Debian before but I haven't run into these issues before so I was wondering if there was someone who has used Veeam with Proxmox and resolved these issues.

veeeam agent 6 supports debian 12 as i see at https://helpcenter.veeam.com/docs/agentforlinux/userguide/system_requirements.html?ver=60

proxmox is a little bit special, as it isn't using debian kernel but kernel from ubuntu. maybe this is the problem.

I'm sure the OP sorted the issue out, but leaving this here just in case anyone stumbles onto this post, like me:
[GUIDE] Proxmox incremental backups with Veeam

TLDR:
download the deb file for their website (a free, non-corporate email account is enough) and install it:
Veeam downloads
dpkg -i veeam-release-deb_1.0.9_amd64.deb && apt update -y && apt install veeam -y

As a side note, for backing up just the proxmox host you don't need to bother downloading/installing their platform. You can use the agent as a standalone. Just run veeam once installed, it has a UI.

Thank you for that guide. It helped with my standalone machines. I was running veeam-nosnap on them to get around the headers not being installed without realizing. Regardless, the issue I had with the pve volume group being out of space is still happening. It seems to be related to Proxmox running in HA or centralized management since this issue is only happen on my 2 HA nodes and none of my 3 standalone nodes.

To be honest, I was just looking for a way to backup the proxmox host itself, then I remembered I'm quite happy with veeam on windows so I've stumbled on this post.

Now I have a combination of veeam (full backup) , syncback(backup folders on a different drive of same host) , syncthing (replicating filders across hosts) for backing up, on top of proxmox schedule backups for vms, and truenas snapshots for the storage of said vm backups... Oh, the joys of a home lab
