everyone listens to the forums and the trollbox

Hello everyone,

I am trying to improve my online security by using 2 factor authentication through Google Authentication. I've set it up for MtGox and BTCT but I am concerned about what will happen if I lose my phone or it gets stolen. I will lose access to absolutely everything! Or I install  a ROM on top of the phone and lose all my data because I forget to backup.

What is a commonly accepted way of backing up one's Google Authenticator database? Ideally it would be a single file that I can load back into Google Authenticator or something that will be stored offline somewhere (putting it in cloud storage might not make sense in this case).

Thanks in advance.

I was robbed last weekend of about 4.7 BTC's.  My bitcoin client was corrupted when I opened it after a weekend away and would not sync.  After repeated efforts to re install it it still would not sync.  Finally I was able to install a new version on a different user on my computer and download the entire blockchain again and then open my backup.dat only to find a 0.00 balance.  I'm done with bitcoin. 

Ah, you actually mentioned QT  

edit: I still can't seem to figure out how, though...
