What is the best way to bind my journal?

I was using composition notebooks, but I am searching for a very durable alternative that will allow me to remove the pages for making copies. I back my notebook up.

There are ledgers with durable covers, but I fear that the paper will stop being produced, and I don’t want to store paper or change systems again someday.

I am looking for a “last notebook” that I will not need to change.
