Proxmox Veeam B&R recognize moved VM within a cluster?

[liwicom]

Hi all,

We are currently testing Proxmox 12.2 on a test cluster with three nodes. We've encountered an issue where, if we move a VM within the same cluster from one node to another, the backup fails because the configuration file cannot be found.

Our setup uses ZFS, and we replicate VMs for failover and load distribution.

Is there any plan for the Proxmox V2 plugin to allow Veeam to recognize a moved VM within a cluster when not using shared storage, similar to how it works when backing up a VM with VMware and vCenter Server?

Thanks for your efforts,


Andreas

Hi everybody,

In my test, the time between backups was too short when I moved the VM. However, after rescanning the Proxmox nodes in the backup infrastructure, Veeam Backup & Replication updates the VM's location, and the backup completes successfully.

I believe this location update happens periodically, so everything is fine—Veeam does track where the VM is located; it just needs a bit of time to do so.

Thanks, everyone, for your efforts!

For future reference, automatic infrastructure rescan happens every 15 minutes.

I have a 2-node cluster. VM named 'Certbot' on hyper3. Migrated to hyper6. Created a backup job containing only that guest. Ran the job ok. Migrated back to hyper3. Tried to run job again. Failed as follows:

2/12/2026 11:51:28 AM :: Certbot : Configuration file 'nodes/hyper6/qemu-server/100.conf' does not exist

If it makes a difference, disks were on local-zfs storage, so migration was slow (as expected). I've noticed when I add VMs to a job, it requires me to pick them from the host - they are not visible at cluster level (which I vaguely remember from vsphere and hyper-v). Is this expected? If so, this seems like a major deficiency, no? If someone can't migrated guests to different nodes without editing jobs, ouch!

Hello Dan,

I’ve moved your question to the existing topic.
Please try rescanning the Proxmox VE hosts in the Veeam Backup & Replication infrastructure.

Ah, ok. I’ll keep an eye out.
