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

    (on Proxmox side) why is this better then just doing backups to external hard drive? there is the same functionality but with hassle of running additional service.

    Can you give me a bit more details in “The rpi could pull both storages…” part?
