I currently use Google Drive as my provider and they provide 30 days of revisions with the option to increase that. In the event of an incident I would just call them up and request a rollback to X hours/days ago.
For backups you can look into Duplicati, Duplicity or Veeam Endpoint Backup and many other solutions. I currently use the Veeam offering and am very satisfied by the incremental backups.
I also use windows file history, to another CloudDrive, but that is for protection against my own stupidity.
Keeping backups in the way you described becomes mighty space hungry if you store any amount of data (Over 3TB in my case).
In the end the best protection from ransoware is not running random .exes and clicking fishy links.
Domen got a reaction from Christopher (Drashna) in File version history for ransomware protection?
