I wonder if you really mean backup using C# with the question, but if you do, then you:
- open the connection with working connection string
- create a SqlCommand object
- define a backup command in T-SQL
- execute the command using ExecuteNonQuery
- handle possible errors
- close the connection
- dispose the connection

And the backup command itself: BACKUP (Transact-SQL)[^]

i am sure that this below link will help you a lot.
LINK
just read and follow instruction.

here is code spinet.

To BACKUP and RESTORE DataBase through SQLCMD.EXE :
PATH OF EXE:- C:\Program Files\Microsoft SQL Server\100\Tools\binn\SQLCMD.EXE

sqlcmd -S.\SQLExpress
1> BACKUP DATABASE dbName TO DISK = 'path'
2> GO
An alternative, single-line backup command:

sqlcmd -S.\SQLExpress -Q"BACKUP DATABASE dbName  TO DISK = 'path'"
(Note that you must enclose the path within quotes)

To Restore:

sqlcmd -S.\SQLExpress
1> RESTORE DATABASE dbName FROM DISK = 'path'
2> GO

For Restore with REPLACING EXISTING DATABASE
1> RESTORE DATABASE dbName FROM DISK = 'path'
2> WITH REPLACE
3> GO

If you can connect to the database using this string in order to view records, then you should also be able to backup the database: Since you don't specify how you are doing that we can't debug that part for you, but there is an example here: http://www.geekpedia.com/tutorial180_Backup-and-restore-SQL-databases.html[^]
