Hello, I am reading the documentation and so far I manged to install proxmox client for backup server on Ubuntu 20.04 which is not an virtual machine and I succesfuly backed up it from host side to proxmox backup server, however I can't see in documentation how to set up incremental backup for this machine. Since it is not an VM, how can I use incremental backup and is it even possible to do so with physical hosts? Do I need to run proxmox client from host with crontab or what?
