Yeah.  It will most likely work on any system that's been successfully 
running 0.20, so it's not really bad for someone to expect it to do so.  
And, the likelihood of its failing on the "one or two" systems that will 
actually need the backup to go back to a 0.20 DB is rather 
small--perhaps close to negligible.

I'm just mainly looking to put a disclaimer in here so I don't get 
blamed when things go wrong.  :)

That's great.  I hope once 0.22 comes out, you'll be able to disable 
that in preference to a built-in database backup that ensures it occurs 
when it won't affect recordings and that should ensure data integrity.  
Perhaps if I quit my job so I'd have more time to spend on all the 
things I want to do for Myth...
