Hello,
im used to start9, but curious about umbrel for my non-btc stuff ( nextcloud, jellyfin, etc) as it seems easy enough to access that stuff via tailscale over clearnet...which would be pretty cool.
my backup is with the backup capabilities of umbrel, or lack thereof. if i load ubuntu onto an old mini computer of mine, install umbrel, and then mirror the umbrel folder onto an external hard drive...is that effectively how one would backup the media?
This post might be more relevant and engaging in the ~lightning territory.
