Here is my setup:

  • I have two proxmox installations (totally not related) on totally different locations
  • on both instances I have a few CTs and VMs
  • on both instances I run “backup job” where I create backup to a external USB drive - this is a “first” backup from where I can quickly restore if needed

What I want:

  • I want to have a separate (off-site) backup
  • I have Raspberry PI with 5TB USB storage
  • I want to use this raspi for both Proxmoxs

What would be the best solution for this?

What I was thinking (I don’t think this is the most elegant solution):

  • install tailscale on raspi
    • (same on both proxmoxs)
    • create CT and install tailscale on it
    • in some interval push backup file form proxmox to CT and then this CT pushes backup over tailscale to raspi
