I'm trying to get jitsi working on an OpenVZ 7 server from flipperhost and having to wipe the server and restart to fix lots of repository issues and other obstacles. I may do this 7 times in an hour depending on where and how I fail as I'm documenting what I'm doing.
This means that I'm rerunning certbot and generating new (old) credentials each time - which obviously has a limit.
Can I copy my certificates 'somewhere' and then restore them to my system as if I reran certbot on a virgin install (no nginx/no apache) and then have them 'work'?
What files do I copy off and then back on and are there any other steps I need to take?
