Just a bit of complaint: if you need to highlight how important it is to make a backup or set up automatic backups, tell the users how to do that or at least lead them to a page which explains how.
This is one of the (small) gripes I have with Fedora (at least the KDE Spin, not sure about the GNOME edition): it doesn’t really have an “official” way to handle backups. Distros like Linux Mint do a better job here.
Yes, you can use pretty much anything and I ended up using Restic, but it’s not great for your average “office” user who would rather just have an entry in the system settings where they can configure a reliable backup easily. Then add a restore process to the installer.
Apple’s Time Machine is a good template in terms of UX I’d say, it’s built-in, easy to setup and also easy to restore either single files/folders or a whole system with an option in the setup assistant.
