backup mail server

[Jared Watkins]

How long have you been using this setup... and have you ever had any 
problem... or needed to do a failover.. or a failback? Do you dedicate 
nics for the replication.. are they GB?  Do you have any stats on the 
typical data rates for the replication under normal load?  

I've thought about using this setup as a poor mans san for a simple hot 
spare...  but I've not known of anyone actually doing it in production.. 
so I'm interested to know your experiences.  I'll assume you are running 
on hardware raid.. and doing backups... but what about using the LVM and 
snapshots?

Much thanks you brave soul...
Jared
