I'd suggest trying amanda out.  It can verify backup integrity to the
extent that this is possible without shutting down to single user.  I
have no idea if it will really speed things up for you, but it is
architected to use each component of your network, disk, and tape
subsystems to their best (eg. dumps are done to a holding disk over the
network and from there to tape at the best tape transfer speed, with
optional compression inbetween).  It is also highly automated, making
backups just a little less boring.

(Personally I wouldn't touch BRU with a 100,000 foot pole either! ;-)
