Vault doesn't gzip images before going to tape.

Vault is using the NBU core to perform all of the duplication functions.  At 
its simpliest level it is merely automating several manual tasks.  It uses 
bpduplicate to identify the candidate images based on the selection criteria in 
the dup_param file and then it creates a BID file which it uses to then begin 
the duplication process.  I don't know of any switch with bpduplicate that does 
compression at the software level, and believe me, I have gone through this guy 
with considerable effort.

As for #2, true...and unfortunately I can't help you much there Jeff, sorry.
