That’s not what I’m talking about, I mean for your content as well as following/follower npub list
Discussion
Your NPUB is public by being public anyone has public access to your history. DM’s as well.
No one can view my DMs via public key
Oh I see. In that case Nostrgram keeps your history of follow list. You can restore from there. Everything else you can broadcast to different relays for backup so that if one goes down you can sync from others.
I think that’s for if a glitch causes you to unfollow or lose followers. You’d have to be able to download the following/follower list to really restore to a new npub should you lose access to the existing one as you can’t force the refollow
