I've been using eFa for 3 years now and I'm loving it.

Currently I am running eFa 4 on centos 7.
Recently I have had some troubles with some of my physical hosts, so I've been thinking is there an easy (lazy) way to do periodically configuration export. The idea is that I don't want to (for various reasons) do backup of my whole appliance, but simple config backup and export, so if anything bad happens I can quickly install centos 8 minimal and run eFa installer, then import the backup config, and presto change-o I have eFa running up again

I would like to be able to do this automatically with cron and some bash script, but what are the steps (commands)?
Has anyone tried something like this?
Thank you.
