My primary 'backup', or easy recovery method is that I use ZFS, and take snapshots via sanoid frequently. I have a mydumper jump making backups of my mariadb server. I use syncoid to doing sends to external storage. So most things can just be fixed by copying the files from an older snapshot.

I also have a completely separate backups of my system made using borg to storage I have at borgbase.com, but this only happens a couple times a week, and is only my 'important' data and not large things like downloaded video/music/etc. I am thinking about switching borg out for restic though, since restic is also compatible with borgbase.
