I just finished reading the WIKI on Backup/Restore and Disaster Recovery (Single Machine). Our configuration is split. We have a separate machine designated as our MTA and another machine for our Server/Mail Store/LDAP etc. If the MTA goes down all I need to do is to reinstall with the same version and apply my custom configuration changes which I have saved in CVS.
However I recall that during a multi server installation that you need to install the LDAP / Mail Store machine first. So now I am looking at what happens if our LDAP / Mail Store machine goes belly up.
What other things do I have to take in consideration when reinstalling this server since I already have an existing MTA box installed? (Assume I would follow the instructions from the Disaster Recovery of a single server machine)
