Proxmox Backup and the and the vzdump hook script
My setup I use the Proxmox Backup Server to create backups of my VMs. The Proxmox Backup Server runs as a VM on a different (TrueNAS) server. The server is connected to a PDU. Therefore the PDU Outlets must be switched on and off… Here is my (preliminary) vzdump hook script #!/bin/bash #set -x remote_user="<remote-user>" remote_host="<remote-host>" backup_host="<proxmox-backup-server>" remote_storage="vaultpbs" replication_process_name="zettarepl:" check_backup_task="ssh ${remote_user}@${backup_host} proxmox-backup-manager task list" check_replication_task="ssh ${remote_user}@${remote_host} pgrep -f ${replication_process_name}" shutdown_backup_host="ssh ${remote_user}@${backup_host} shutdown -P now" shutdown_remote_host="ssh ${remote_user}@${remote_host} shutdown -P now" if [ "$1" == "job-init" ]; then logger "Backup starts.

Before backing up the VMs Switching on the server Wait until the server is running Activate the remote_storage - backup destination After the backup of the VMs Check whether other processes are running on the backup server other Proxmox backup processes or (TrueNAS) replication processes Shutdown of the PBS VM Shutdown of the server Deactivate the remote_storage - backup destination Switch off the PDU outlets Add the script to the backup job After creating the script, it needs to be activated so that it is used during a backup job. ...
