Install Proxmox Backup Client on AMD64
This will work for any OS capable of installing .deb
files such as Ubuntu and Debian
Installation
Start by getting the GPG key
wget http://download.proxmox.com/debian/proxmox-ve-release-6.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg
Then add the APT repository to your system
echo "deb http://download.proxmox.com/debian/pbs-client buster main" >> /etc/apt/sources.list.d/pbs-client.list
Then update your APT cache

apt install proxmox-backup-client

export PBS_USER_STRING=''
export PBS_SERVER=''
export PBS_DATASTORE=''
export PBS_REPOSITORY="${PBS_USER_STRING}@${PBS_SERVER}:${PBS_DATASTORE}"
export PBS_HOSTNAME="$(hostname -s)"
echo "Running Backup for $PBS_HOSTNAME ..."
proxmox-backup-client backup root.pxar:/
echo "Done."
