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. :)
