Personally, I put the encryption key on a CD (several copies) and on a 
brand new disk on key (again, several copies), and store them in a safe 
I rented at a bank. I also have some other copies (this time the key is 
itself encrypted) which I store at my lawyer's safe.

Then again, my company makes a living from selling online backups. I 
will readily grant that that procedure is somewhat of an overkill.....
