backup-failover server

Hi.
How do I implement backup-failover active-passive in nagios XI Enterprise?
I have another computer with the same HW as the productive nagios

Here is a document that goes over a few options for high availability. If you're not running Nagios XI on a hypervisor like ESXi, then one of the open source solutions may be suited to your environment.

There's also what we call "MA" or Medium Availability options that you can do that perform copies of configs from one server to another, update databases with appropriate information as needed, and then have one box monitor the other in an active/passive manner. This way, if the passive box sees that the active box is not responding, it can start monitoring with the last known good configs, and generally take over where the master left off. They won't be in perfect sync, but at least your stuff will be monitored. Moving things back is as simple as the secondary (which is now active) checking to see if the primary (which is now passive) is available again, and then reversing the process.

Self-serving advertisement here: There are a few caveats here and it's more complicated than a forum post, but our company does assist with this sort of thing for customers if that's something you're interested in pursuing.

Good info, thanks for jumping in, Eric!

mralvarezm, does this give you enough information to get started? Did you have any more questions on this topic?
