For my webserver, mysqldump to a secured folder, then restic backup the whole /svr folder, then rsync the restic backup to another server. Also have a system that emails me if these things don’t happen daily. The log files are uploaded to a url, the log file is checked for simple errors, and if no file is uploaded in time, email.

Of course, in my case, the url files are uploaded to - and the email server… are the same server I’m backing up… but at least if that becomes a problem, I probably only need the backups I’ve already made to my second server.
