Well if the site is not complex then something like Grav these days is much better IMHO
I've been eyeing Grav for a while. It does look very interesting. ANy guesses as to pros and cons vs. WordPress? Beyond the obvious flat file vs database differences...
Ever since discovering Wiki.js, I like the idea of using git for versioning backups and deployments.
You can automate backups of the MariaDB, though. Not all that much different. Lighter, on big loads. GIT is actually a very heavy process. Great for tiny things, but bad for big ones.
