We had no end of trouble when we were using required interface. We finally
just made it so that we always used the name of the backup interface in the
class and in the bp.confs (both for servers and clients). We have a few
clients that back up over the production network. We enter them in the class
with the production interface name and we use the production interface of
the server in the local bp.conf.

We haven't had any problems backing up or restoring since we did this.

We also have quite a few interfaces on our backup server, and Cris's 
solution works well from the server perspective.  What I don't have as 
good a handle on is when both client and server have multiple interfaces 
and we want backups and restores to go through a secondary interface on 
both client and server.  I don't have a cookbook approach that always 
works, and for many boxes our group doesn't do the administration.  I 
usually end up with a combination of using REQUIRED_INTERFACE in the 
bp.conf, altnames entries so the restores work regardless of which 
interface the requests come through, /etc/hosts or DNS entries and 
client names for the specific interfaces.  But usually the approach is 
to keep trying different things until it works.  If someone has a 
cookbook/checklist they use for this, it would be majorly appreciated!  
Thanks....Gerrit
