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?
