Darkreading.com reported that "Based on responses from more than 1,000 IT professionals, business executives, and backup administrators, Barracuda found that 40% of IT organizations surveyed don't use third-party backup tools to protect Office 365 data."

SharePoint and OneDrive are unable to retrieve single items/files; they must restore an entire instance.
It's unlikely that such short retention policies meet most compliance requirements.
