January 26, 20251 yr I have been doing rsync backup between my main and backup servers for years. The backup server is off until powered on via IPMI. It is automated and works great but both servers have been in the same LAN. Ideally, the backup would be offsite in a different location than the source. We recently purchased another home 270 miles away so I am moving my backup server there. Requirements for Off-Site backup: Backup server powered off when we are not in the "remote" home until backup is needed Secure/encrypted connection between LANs at source and backup location Ability to continue to power backup server on/off via IPMI Remain completely automated with no user intervention required as it is now I looked into how to establish a Wireguard, Tailscale or site-to-site VPN connection between the two locations via the backup script. Although I think this is possible, it was not totally straightforward and I was spinning my wheels a bit. UniFi Site Manager already lets me manage both LANs remotely via Teleport as I have UniFi Cloud Gateway Ultra routers/gateways in both locations. While doing some minor configuration changes on both LANs, I came across the Site Magic SD-WAN capability in Site Manager. With a few clicks, I had both LANs linked in a mesh configuration. It was super easy. I can now access devices/resources on either LAN as if they were all local. Site Magic creates Wireguard encrypted tunnels. I have yet to try the backup to a remote server as I have not moved the backup server, but, all indications are it should work seamlessly. [UPDATE]: Remote backup works as expected. I just had to make sure the target server was recognized by the source server for automated SSH purposes. Here are the two sites linked in what I called MadMesh: Requirements to use Site Magic: Ubiquiti routers/gateways from a list of supported devices (the older USG is not supported) At least one gateway with a public IP address (both of mine have public IP). A change in public IP address by ISP is automatically supported. Non-overlapping subnets (mesh configuration) Same owner for all included sites Site Magic SD-WAN supports Hub and Spoke and Mesh configurations Complete description is found here.
