Files deleted from SharePoint Online go into a Recycle Bin and can be recovered locally for up to 93 days and by Microsoft for a further 14 days.
If lots of your SharePoint or Microsoft Teams files get deleted, overwritten, corrupted, or infected by malware, you can restore an entire shared document library to a previous time within the last 30 days. The restore will undo all the actions that occurred on both files and folders.
With online version history, you can see and restore older versions of your files stored in SharePoint Online.Share
