@WbrJr I'm on Manjaro Linux but principles are the same. I have an SSD boot drive and a 4TB hard drive for /home data etc. I also have a second 4TB drive for backups:
Timeshift app - does snapshots of OS to backup drive. I have 4x hourly snapshots, 2 daily ones, and one weekly one. This allows easy roll back from any updates or upgrades that went wrong.
luckyBackup app - does a full rsync backup daily of /home data and configs. There are other rsync apps too, and you can opt for versions it you have space. But usually I've been fine with recovering anything I deleted or overwrote by mistake. I do this more for hard drive failure. I do also have one additional 1TB drive I keep in a safe. I connect this myself once a month or so for an offline backup.
