Hi Fred -

We don't use any cluster software.  Our backup server is just a full copy
of our data and nothing more.  So in the event of a failure of the master
our server clients don't automatically fail over or anything nifty like
that.  This filer isn't customer facing, so in the event of a failure of
the master there is no customer impact.  We use a slightly modified zrep to
handle the replication between the two.

thanks,
liam
