Give LZO compression a try, it's about as fast as your disk will
provide the data, a bit less efficient than gzip but we've found it a
good tradeoff for lan-based backups to disk. 

A while back there was a discussion on this list about a windows fd
client providing LZO support, you may want to search the archives as I
don't have the link at hand ATM.

Both client and server need lzo compression enabled, so make sure to
build bacula with that option if your distro package doesn't provide
lzo support out of the box. 

All the best, Uwe
