Allow for restoration of individual files/folders in SharePoint Online and hold more than 14 days backup.
Allow individual files/folders to be restored from backup in SharePoint Online instead of it only being an entire site collection backed up (which, if done, you lose any changes to the site since the backup date). Also, keep more than 14 days of backup for SharePoint online sites.
The recycle bin is designed to temporaily keep the deleted files/folders and give you an opportunity to recover the files/folders. And there are two stages of recycle bin, so when a user purges the file in the user’s recycle bin, the file or folder is still available for site admin to restore.
