Failover/DR question

[xiguy99]

I’d like to use one of my 3 XI licenses for failover/disaster recovery. Is it just a matter of rsyncing specific files as a cron job? Is there a list somewhere of what files I would need to copy?

I make a backup of the nagios 01 system via the backup script, scp the file to the 02 system and restore it.
You can scp or rsync the perfdats if you want that on 02.
You'll want to remove the service and host files on 02 before restoring, restore, then run th reconfigure script.
