I have a question on how to mirror a FreeBSD
installation / system.
This environment will have two identical / separate
systems referred to as “System A” and “System B”
- I want to install FreeBSD on to “System A”
- Once that installation is complete with selected
ports and custom applications, I want to make an exact
duplicate of “System A” on “System B”
I don’t want to do this with drives in the same
system, rather I would like to “clone” “System A”
Also, it would be nice to be able to do this as a
“mirroring” solution to keep a clone over time of the
system in the case of failure of either “System A” or
“System B”
Is this possible to do? If so, any direction on how I
would do this would be welcome.
Is there a port / application that enables this?
Thank you in advance!

I use rsync to mirror and freevrrpd for failover via heartbeat.
Freevrrpd should be in ports. Freevrrpd gives both systems the same
virtual ip so you will need to avoid rsyncing the configuration file for
it. There is a nice feature that makes you trigger a script when one
system goes down to initialize configurations on the system taking over.
Mind you, if you are using firewall as part of the system you will need
to alias the interfaces and use dns names in configuration files.
Just my nickels worth
