DAT drives make very little noise if you keep the data streaming to
them as fast as they can handle it.  If you don't they may make
clicking noises every now and then.

I'd highly recommend you look into amanda.  I use it here, and as long
as you're willing to spring for more tapes than you probably
originally intended, it does a wonderful job.  I also recommend
turning off the drive's hardware compression and letting amanda handle
it with gzip (unless CPU time is a big deal).
