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!

    Is there a benefit for splitting your services on 2 hosts?

    I don’t know about OPs situation, but I have a mini-PC as proxmox hypervisor too addition to my main server. Mini-PC is located middle-ish of the house as it’s running home assistant with ZWA-2 and the location helps a lot with Z-wave coverage. But added benefit is that I can (within the pretty strict resource limits) move VMs to the mini-pc when doing maintenance on main server. It’s pretty handy to move PiHole and some other small stuff to another host so that everything on network still functions even if one hypervisor is down.

      Interesting. I do not know a lot about Home Assistant devices, but I thought they would just be communicating via standard WIFI + data encryption. I definitely didn’t suspect there to be a whole new standard of wireless communication to that.

      I understand the thing about downtime, running pihole myself. My setup is rather simple and centralized on purpose and I don’t really mind the few minutes of “filtered DNS” downtime while pihole and pve are rebooting. As my UniFi Dream Router 7 is the firewall / gateway / DHCP server anyway, I just use pihole as primary DNS and 1.1.1.1 as secondary DNS. It’s not filtering “bad domains” via DNS, sure, but I got adblock origin and other browser extensions dealing with whatever comes along anyway.

      But, yeah, for redundancy and always-online-production-setups it’s actually great having a secondary pve as a temporary stop-gap. Plus, it’s a nice and kinda fancy setup, of course. Always appreciated in selfhosted :)

      while the machines are physicaly next to esch other i also runy whole home automation over zwave. the reason i have 2 machines currently is that the media server used to run truenas and i virtualized everything there. since truenas deprecated its public build repository i wanted to replace it with open media vault, but since i dont really used shares i figured that proxmox would be better suited. so i set up a machine where i host all the services until i figure out how i want to run my media-server.

      i still need to find a way to setup a simple sambashare via a web gui and a good backup solution.
