Remote Blob Storage Affects Database Backup

Microsoft SharePoint Server content resides in your content databases, unless you’re using Remote Blob Storage. RBS externalizes your content and gets it out of Microsoft SQL Server. In such a scenario, SQL Server database backups aren’t adequate for disaster recovery. Different vendors implement RBS in various ways. If you decide to use RBS, you should consult the vendor for the best way to back up your externalized content.
