Being new and very bad in English, please apologize in advance for faults or other clumsiness.
I have two servers with ip failover, the premeir is used for production, the second in case of crash the first.
I use an ip failover to be able to switch from one to another without having to change the DNS. The ip is mounted by hand it is not load balancer.
On the first I set up for test, a certificate let’s encrypt (previously I used startcom good it was a bad choice considering what happens today).
My question is about the second server, should I just copy the / etc / letsencrypt / folder to the second server, or should I do otherwise?
I specify that I made the backups on a third server.
Thank you in advance for your help.
