As an aside, using pre-compiled amanda packages often leads to no end of 
troubles.  Since amanda configures a lot of stuff at compile time, you're 
left guesssing what values the packager chose.  The standard 
recommendation is to compile it yourself.

That depends on your tape drive and OS.  On some OSes and with some 
drives, it's via device names -- /dev/rmt/0n doesn't use compression and 
/dev/rmt/0cn does.  With some tape drives and OSes, you use 'mt' to toggle 
either the compression flag ('mt compression 1') or set the correct 
density ('mt setdensity 0x8c' for an Exabyte 8mm, e.g.).
