For something on the timescale of a year I would just keep the system that you already have up and running. It it were much longer than that I'd go with a bank vault that contains the access keys and something like tarsnap and yet another backup with another cloud provider.

I'm assuming all my electronics fries, papers burn and memory goes away. (to be safe)

Bank vault might be a good idea (assuming they id me fine)

Store one copy in a gmail account, and another on imgur.

And tattoo the site+username+pass on your thigh.

Good thinking!

I wonder if a system like this would be good for your general problem:

Generate a random seed sentence of so many words. From the secret seed + site domain name generate a password

Store piece of paper with:

Algorithm (could be public in github too) Seed word Site names

Wouldn't biometrics be good use case here since OP doesn't want to remember it?

Yes if you can get a biometric that you can keep secret, and can easily access.

Finger prints aren't very good (they end up everywhere!). Retina scan? Not very cheap I'm guessing. Face? Definitely not secret.

Yes!! Is there a solution like that?

For a year? a burned CD in a safe deposit box. Also a USB key there for convenience. Basically paying for physical security of the devices/data.
