I'm running proxmox-ve: 6.0-2 (running kernel: 5.0.21-5-pve) and as far as I understand "man vzdump"
should run /etc/qemu/fsfreeze-hook if the qemu-guest-agent is installed and the kvm config contains "agent: 1". A "qm agent 6207 ping" from the proxmox host results in an entry in /var/log/syslog with "qemu-ga: info: guest-ping called". A "qm agent 6207 fsfreeze-freeze" also starts the script /etc/qemu/fsfreeze-hook inside the VM. But the script is not called if I start a backup from the webgui. Any ideas?snapshot mode
This mode provides the lowest operation downtime, at the cost of a small inconsistency risk. It works by performing a Proxmox VE live backup, in which data
blocks are copied while the VM is running. If the guest agent is enabled (agent: 1) and running, it calls guest-fsfreeze-freeze and guest-fsfreeze-thaw to
