I am running PBS as a VM in Proxmox, I have a cluster with 3 nodes, and PBS in running on one of them, I have an external USB drive with USB passthrough to the VM, everything works fine, backing up all the different VMs across all nodes in the cluster.
Today I tried to backup the PBS VM, I know, it sounds non-sense, but I wanted to try, in theory If the backup process takes a Snapshot of the VM without doing anything to it, it should work.
Initially it failed when issuing the quest-agent 'fs-freeze' command, that makes sense, because while backing up the PBS VM, itself (PBS VM) received an instruction to freeze itself, and that broke the backup process, no issues here.
Then I decided to remove the qemu-guest-agent from the PBS VM and try again, in this scenario the backup of the PBS VM on PBS worked fine, because a Snapshot was taken without impacting the running PBS VM.
So, my question is, please could you explain what is happening here? Are my assumptions (as described above) correct? Is everything working as per design? Should I do it differently? Thank you
