Ask HN: Where do you store the backup of your password store

I've been using a desktop based password manager for years (KeePass). It dawned on me a few months ago: I backup my password store on a personal FTP account which access is protected by a complicated password that I can only retrieve from the password store itself.

So if I were to loose access to my primary password store (say, in a house fire), I would loose access to the backup as well. I have a few copies of it on a laptop and USB drive now but if they are all in the fire it wouldn't help.

Asking to reset that FTP password wouldn't work either since my primary mail address for confirmation purposes is also behind a password that is only in the store.

The only solutions I can think of is to use a second memorable master password to protect access to the backups. (Or the same master password since if it is compromised the backups are useless anyway). Or a memorable password for the recovery address.

What is everyone else doing?
