Sorry, I'm not sure exactly what you're describing here:

* What does "backup a different snapshot" mean?

* "to help protect against corrupted data in the latest lazy mode backup": 
  MinimumFileAge is supposed to do this for you, so the chance of a 
  corrupted file in a lazy backup is actually lower than with a forced 
  snapshot of all files unless the moment of that snapshot is carefully 

* "picking which change level to restore from": what's a change level? 
  lazy vs snapshot?

Cheers, Chris.
