My laptop (1Tb MBP) is backed up via both Carbon Copy Cloner (for a bootable backup) and Timemachine (for a snapshot backup) to a USB-C external RAID enclosure:

I have one at home and another in work (both encrypted)

My laptop also has an encrypted, snapshot cloud backup to Backblaze B2 storage using Arq Backup:

I use Resilio Sync to sync my documents folder between my laptop and a Synology NAS (with RAID). My NAS also downloads periodic backups of AWS S3, email, Github etc.

This NAS is backed up locally to a standard external drive as well as Synology's own cloud backup service "C2" using Hyper Backup

Although this seems extreme, I've actually had to make use of all the services at one point or another.
