Office 365 (OneDrive for Business) - File Restore
Files Restore is a complete self-service recovery solution that allows administrators and end users to restore files from any point in time during the last 30 days. If a user suspects their files have been compromised, they can investigate file changes and allow content owners to go back in time to any second in the last 30 days. Now your users and your administrators can rewind changes using activity data to find the exact moment to revert to.
