The new FILESTREAM funcationality in the SQL Server 2008 allows you to configure a VARBINARY(max) column, so that the actual data in stored in the file system/storage area rather than within the database.
To enable FILESTREAM feature you must configure SQL Server Service for that instance.
sp_configure 'filestream_access_level' , 2
go
Reconfigure
Note : Database Mirroring is not compatiable with FILESTREAM data
