What to backup so I can keep digitally signing with a gpg key pair (self.asklemmy)

Hey so I'm new to the world of gpg/pgp. Using a test gpg key pair I created, the goal was to digitally sign a odf so I was wondering what do I backup so I could keep signing digitally using this key in case shit hits the fan and my computer no longer works? Using seahorse, I perfer it to the terminal, the options are to either export the public key or the secret key and I'm honestly confused should I do both or just the secret key? I did notice people also just take a copy of their .gnupg directory but I feel thats just to backup all of their keys including imported ones rather than a singular one. Any help is appreciated preferably as if you were talking to a 5 year old

The TLDR: Just created a gpg key pair now how do I back it up?

Been using PGP for years, everything you said is correct. Create two keys so you have an extra one and make sure your second key is able to decrypt all files (just add it as a recipient).
