I‘ve got 2 Machines with Proxmox on both installed. One hosts my data and media and runs Services like Jellyfin, NAS,… The other one is a Mini-PC that hosts my Services like Adguard, Home Assistant,…

Whats the best way to Backup the data and configs of those 2 machines? Installing Proxmox Backup Server on each and store the Backups on a seperate HDD? Or would it be better if a move all the services to a single machine and use the second only for backups?

thank you!

    My Mainboard only supports a single nvme-drive. thats why i store the os and the data of my vm/lxc on it. everything else are good old hdd. is it possible to restore this drive, if i install pbs as a lxc on this very drive?

    sorry, i tried to read through some guids already and the more i read the more im confused /(

      You should not be able to restore the whole drive, like you would restore a VM. This is because you would first need to have Proxmox VE already running to restore the drive which runs Proxmox VE.

      If your NVME drive dies, you would have to do what I outlined above:

      • get new NVME drive, install in server
      • install Proxmox VE manually
      • install Proxmox BS manually (either lxc container or VM)
      • give Proxmox BS access to backups on external HDD
      • restore whatever you backed up

      Though, to reiterate, I do not know anything about lxc containers.

      I did go through the Proxmox VE backup settings on my server, but I could not find a way to backup lxc containers, only VMs. So maybe Proxmox VE does not support backing up lxc containers? Or maybe it just does not show any lxc container backup option because I do not run any lxc containers?

      I did find this github about Proxmox VE and LXC containers, but I didn’t test it and it only has 1 star, so I’d be wary.

      As a tipp: Even if your motherboard only supports 1 NVME drive, you might still be able to use multiple. You could buy a PCIe card with M.2 NVME slots, if you have any unused PCIe slots on your mainboard. With this, you should still be able to have a RAID setup.

        thx for that write up. seems i didnt understand you correctly the first time (english is not my native language). i already used all pci-slots with sata extensions and a nic. its just a mini atx board with a n100 cpu, so my options are limited. i could mirror the disk to a sata ssd though.
