Ah - I missed that it was in the Archive-specific configuration section but
just noticed it. That makes sense.
Incidentally, the '-9' gzip takes a bit more CPU but isn't
substantially more effective. Since CPU isn't exactly lacking in this
case it is cranked to -9 just to
save any disk space possible since it's still not taxing the processors.
