I assumed we could both run Duplicati, connect over Tailscale and bing bong boom, send files back and forth. But Dupicati only allows uploads and only to its cloud service, not to other Dupicati instances.
Requirements: Needs to be docker, preferably something with a Web GUI. My friend is not tech savvy and I am not physically close enough to help troubleshoot.
PS- I am not committed to Dupicati it just is the most recommended. I’m open to anything simple and encrypted!
Kopia(UI) is a client you run on your system, yes. It’s not containerized or web-managed, though I think there might be a web UI you could host for managing the CLI version. The Docker container on your pal’s setup would just be presenting you with a network folder that you point the backup system at.
