Content uploaded to Microsoft SharePoint is stored within a content database on the SQL Server. As more content is added to these databases, they become increasingly difficult to manage. SharePoint Storage Manager manages content database growth in SharePoint by storing Binary Large Objects (BLOBs) in a BLOB storage location, leaving only the corresponding metadata in the content database. SharePoint Storage Manager uses SQL server Remote BLOB Storage (RBS) technology and hierarchical storage management (HSM) to migrate rarely used files to lower-cost storage devices.
Use SharePoint Storage Manager to improve SharePoint and backup performance, reduce storage consumption through deduplication and archiving, and manage tiered storage.
Regardless of your BLOB data protection and archiving policies for SharePoint, Storage Manager protects all necessary components in an application-consistent state from a single policy-management structure. Protection includes the following objects:
- SharePoint farm components, including web sites, web applications, solutions, service applications, and so on
- Documents and metadata stored in content databases
- BLOB data stored on the file system
The SharePoint Storage Manager feature is supported for the following applications:
- SharePoint 2010 (or later)
- SQL Server 2008 R2 Enterprise (or later)
- SQL Server 2012 SP2 (or later)
