I currently use Borg for all my backups. To have a remote backup I placed my old Synology NAS at a family member and connected it to tailscale (via a tailscale docker container). That way I could also can do Borg backups to that remote NAS.
Though I have problems with the stability of the tailscale connection from the NAS. And honestly, I’m a bit tired to fix these problems.
I would like to have a self hosted backup solution, that can reach the synology NAS. I would like to avoid port forwarding at my family members network (for obvious reasons). I have a VPS in the internet that I can use for a common self hosted contact point (like I setup headscale there instead of using official Tailscale servers).
What would be your way for handling these remote backups?
Never had an issue with Tailscale and have been using it for years.
