None of my services are exposed to the public internet and are only accessed by myself through tailscale. One scenario, which still concerns me is "Away from home, access to none of my devices, need to use public/other computer to access files". Short of downloading tailscale to said computer (which I likely wouldn't want to do/may not be possible, what would be the best way to have a backup entry way? Linode VPS with guacamole and tailscale to remote into a machine on the network? Something different entirely? Let my know what you use/would suggest

I would like to back up my nextcloud data using duplicati, but I absolutely can‘t figure out how to give Duplicati access to the Nextcloud volume. Both are running fine in separate Docker containers. I can’t figure out how to properly mount the volume, below is my current compose for duplicati. Do I need to mount the volume as source? Does it need to be declared or mapped separately? ``` --- version: "2.1" services: duplicati: image: lscr.io/linuxserver/duplicati:latest container_name: duplicati environment: - PUID=1000 - PGID=1000 - TZ=XXX - CLI_ARGS= #optional volumes: - /path/to/appdata/config:/config - /path/to/backups:/backups - /path/to/source:/var/lib/docker/volumes/073ac2751cd65ffd84750e578c38482905c3c7e4851a8cbb0bbbc5c33a285e84 ports: - 8200:8200 restart: unless-stopped ```

I want to upgrade my Pis to something more reliable and not SD-card based and refurbished thinclients/SFF workstations seem to be a viable route. Does anyone have a cheap source for used hardware like this in Germany? I feel like the usual esm-computer, green-IT etc. are a bit overpriced.
