Recently a new restore feature has been rolled out to SharePoint online (Office 365) called “Files Restore”. This self-recovery option allows administrators and site owners to restore deleted files from any point during the last 30 days.
This can be used as a self-service to restore the files and folders in the library you suspect have been compromised by end-user deletion, file corruption, or malware infection – to any point in the past 30 days.
