Hot Spare Server For Icewarp
To set up a hot spare for Icewarp Mail Server you can follow the steps below. This would require both servers to be licensed if you want instant fail over. The other option is to activate the license online for the secondary server after the primary server goes down. This would cause a little downtime in between the registering of the secondary server and the crashing of the primary.
You would need a central file storage server so both servers are sharing the same data and mail boxes. With it set up in this manner the primary server can go down and the secondary server will then step up and take the load until the primary server is back online. This will not cause any issues with users as you will be seeing the same mail boxes and data since you are on a central storage path. You would need to store all the users in a database so both servers connect to this database for the information. The below steps will walk you through the setup.
You can set one server up with this information pointing to the file server and database and then apply the back up file to the secondary server instead of going through each step again.
