when you make a backup of your profile and follows in iris.to, the resulting JSON file doesn't really contain your full profile data, as far as i can tell. what it seems to contain is:

- all your published relays

- all the people you follow

- your public key

what it doesn't contain:

- display name

- user name

- profile picture

- header picture

- bio/about field

- website

- Lightning address

- NIP-05 address
