Since I'm a big user of proxmox and all my systems are debian-based I recently began to use proxmox backup server also for my physical machines! It's quite fast, supports defuplication and I can donwload or mount backup archives.
It sadly lacks a good ux, but I'm still evaulating it because pbs is a tool that I'm already using heavily, so I don't mind reducing the amount of individual software needed to carry on my work.
