I’m using Arq (https://www.arqbackup.com/) to back up all my computer to my unused dropbox cloud storage (you get 2TB storage and I only use 100GB, hence 1,9TB free backup storage 
). Arq works with pretty much any cloud storage (except iCloud) and backs up hourly any folders you specify. So next to versioning i have a full hourly backup of my vault.
Edit: Mac & Windows. I’m not affiliated There’s also free alternatives, but less end-user friendly: Duplicacy (https://duplicacy.com/)
