It doesn't really matter, in the long-run.  "Supported" doesn't mean 
they'll fly out and recover your data if it screws up.

(There are places that will "guarantee" that, but they are um... a 
little pricey, and they want complete control of your backups.  GRIN...)

I say: Use whatever you're comfortable with.

And by comfortable, I mean... that you've actually restored data from 
and know you can recover to whatever level (bare-metal, filesystems 
only, etc) you want.

Familiarity and knowledge about how your backup system works (and 
documenting it such that someone else could follow it if you were "hit 
by a bus") is more important than using some fancy "supported" backup 
system.
