Autoback of SQL Database using C#.net Application

Backing Up a Whole Database
BACKUP DATABASE { database_name | @database_name_var } 
  TO  [ ,...n ] 
  [  ] [ next-mirror-to ]
  [ WITH { DIFFERENTIAL |  [ ,...n ] } ]
[;]

Backing Up Specific Files or Filegroups
BACKUP DATABASE { database_name | @database_name_var } 
  [ ,...n ] 
  TO  [ ,...n ] 
  [  ] [ next-mirror-to ]
  [ WITH { DIFFERENTIAL |  [ ,...n ] } ]
[;]

Creating a Partial Backup
BACKUP DATABASE { database_name | @database_name_var } 
 READ_WRITE_FILEGROUPS [ ,  [ ,...n ] ]
  TO  [ ,...n ] 
  [  ] [ next-mirror-to ]
  [ WITH { DIFFERENTIAL |  [ ,...n ] } ]
[;]
Backing Up the Transaction Log (full and bulk-logged recovery models)
BACKUP LOG { database_name | @database_name_var } 
  TO  [ ,...n ] 
  [  ] [ next-mirror-to ]
  [ WITH {  |  } [ ,...n ] ]
