I feel like this is what 'owning' your data means.
Love this! Great work guys! umbrel (npub1agh…mhct)
quotingIntroducing a new feature in our Nostr Relay app for Umbrel 🚀
nevent1q…srzd
Now you can sync the private relay on your Umbrel with your public relays, and back up your past & future Nostr activity, even if the connection between your client (like Damus) and your private relay goes down.
Just enter your NIP-05 or npub, and you’re all set!✨
