What is everyone doing? SELinux? AppArmor? Something else?
I currently leave my nextcloud exposed to the Internet. It runs in a VM behind an nginx reverse proxy on the VM itself, and then my OPNSense router runs nginx with WAF rules. I enforce 2fa and don’t allow sign-ups.
My goal is protecting against ransomware and zerodays (as much as possible). I don’t do random clicking on links in emails or anything like that, but I’m not sure how people get hit with ransomware. I keep nextcloud updated (subscribed to RSS update feed) frequently and the VM updates everyday and reboots when necessary. I’m running the latest php-fpm and that just comes from repos so it gets updated too. HTTPS on the lan with certificates maintained by my router, and LE certs for the Internet side.
Beside hiding this thing behind a VPN (which I’m not prepared to do currently), is there anything else I’m overlooking?

I’ve used rclone with backblaze B2 very successfully. rclone is easy to configure and can encrypt everything locally before uploading, and B2 is dirt cheap and has retention policies so I can easily manage (per storage pool) how long deleted/changed files should be retained. works well.
also once you get something set up. make sure to test run a restore! a backup solution is only good if you make sure it works :)
As a person who used to be “the backup guy” at a company, truer words are rarely spoken. Always test the backups otherwise it’s an exercise in futility.
