If you're getting 417GB onto a 400GB tape, you're getting compression.
You're just not getting MUCH of it.
What kind of data are you backing up? Not all data compresses well.
English text compresses about 4:1 on average. Binaries, typically not
much at all. Digital images, digital video, zip archives, MP3 audio?
Forget it. Databases? Sometimes you get lucky and get 10%-15%
compression, sometimes they don't compress at all.
