Storing encryption keys for backup drives (lemmy.world)

I'm planning to setup backup on my nas with the 3-2-1 backup rule.

For the backup disks I want full disk encryption, but I also want to be really sure that I don't lose the encryption keys if I lose my phone and computer where I have my password manager.

What is a good practice to store the encryption key(s)?

One thought I had was to have an unencrypted partition on the backup disks that stores an encrypted keepass database with the key.

Any tips or experiences are welcome.

PS. I want to avoid cloud-based options.

Also, keep in mind that really good passwords can be easy to remember or recover. Pick your favourite book at home, get the last word of the first 10 chapters and put all of them together. You get a password that is impossible to bruteforce, literally written in your home but impossible to guess for anyone else but you. Of course it won't be easy to type. But is still a good main password for a password manager which stores all the others.
