I know there's no 100% in security. But for business users (yes that is a range of use cases), if they are on Windows 10, they have My Documents pointing to a OneDrive (or GDrive, DropBox, Box, etc.) share, and that share has versioning turned on - then would recovering from Ransomware be pretty fast and easy?
In case of Ransomware then just reinstall a clean Windows, point to OneDrive, and for all files, go to the last unencrypted version of the files.
Assuming all other data is hosted (email is hosted Outlook or Google, Salesforce, etc.) then isn't it a quick and easy recovery. For the users (servers is a very different problem).
Or am I missing something?
Note: I am not asking for an opinion here (a no-no on the site). I am asking what specific issues would remain in this situation.
