A large chunk of data stored in a database, which is usually recognized by its location and size instead of its structure is known as a binary large object (BLOB) in SharePoint 2013. These BLOBs are mostly unstructured data and we can store them in SharePoint content database with structured data or associated metadata. We often refer them as unstructured data i.e. audio and video files.
These BLOBs are usually very large in size and they are incontrovertible. Each version of the BLOB must be stored with new copy of the same therefore database usages can be increased very quickly. These BLOBs can utilize lots of server resources and can consume enormous space. This is the reason the total size of its BLOB can be expanded quickly and become larger than structured data and document metadata in the database. Remote Blob Storage (RBS) is the best way to move BLOB data away from the SQL server database.
RBS consists of following components:
* RBS client library :
The BLOB storage with SharePoint 2013, RBS provider components and SQL server are coordinated by RBS client library that consist of managed library.
* Remote BLOB storage provider :
The RBS provider communicates with the BLOB store, which consist of a managed library and a set of native libraries i.e. SQL FILESTREAM provider
* BLOB Store :
BLOB data are stored in an entity called a BLOB store. This can be a file server with a SMB, SQL server DB, or content addressable storage (CAS).

SQL Server 2008, SQL Server 2008 R2 and SQL server R2 Express comes with incorporated add – on pack of RBS, Remote Blob Storage is SQL server library API. BLOBs can be stored outside of the content database in SharePoint 2013 by using this RBS feature. We can reduce immense storage space on SQL server database by externally storing the BLOBSs. The SQL server database can store only the metadata for each BLOB and that BLOB is stored in the RBS store.
