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

Have you looked at Proxmox Backup Server? I have not used it, but I believe it is made to handle remote backups.
Any reason for not using proxmox backup? :)
Where should I install it? I guess raspi is not sutable
On the proxmox hosts alongside pve. Then pull each other’s backup storage (via VPN/ssh tunnel).
The rpi could pull both storages as a second backup, e.g. via rsync. There is a pve port for the rpi, maybe also for pbs.
(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?
Dedup, incremental backups, backup verification
Cronjob with rsync command to copy file contents
