The biggest problem with this is that you're most likely looking for 
off-site replication:  a fire/tornado/theft would affect both members of 
the cluster.  And doing DRDB over a slow connection (i.e. WAN) is going to 
*seriously* slow down your backups...

That's why so *very* many of us have asked these same questions so *many* 
times.  What I think many of us (read:  ME!) would like is a way to 
replicate a backup from one server to another without hammering the host 
that needs to be backed up twice.  After all, the fact that it needs to be 
backed up means that it does real, valuable work;  whereas the backup 
servers spend most of their time idle, just *begging* to replicate data 
somewhere else...  :)
