no, in sense of configuration. this is a known limitation of gzip 
compression. if you're on LAN (gigabit) you might wan't to disable it if 
you backup to tape (use tapes hardware compression) or if you backup to 
file, use a compressed filesystem (maybe: http://miio.net/wordpress/
projects/fusecompress/ -  LZO is fast)

yes in sense of coding: you could write a patch. :)
