In some cases, though, it makes sense.  Sometimes one just can't spare the 
cycles on the clients, or compression makes the whole thing just take too 
long.

But, yes, HW compression does involve one lying to amanda, and that lie 
just being a guess based on your estimates of how well your data 
compresses.
