SharePoint natively stores Binary Large Objectsi (BLOBs) — the documents and other types of unstructured data that are the actual content in SharePoint — as well as their associated metadata, within the Microsoft SQL Server relational database.

This white paper discusses alternatives to traditional SharePoint backup strategies that can help organizations achieve their Recover Point Objectives using native SharePoint and SQL backup tools.
