An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

Today i tried to restore the backup Database to another SQL Server 2008 R2, but i got the error as

"An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)"

Additional information:
The media family on device 'Backupfile.bak' is incorrectly formed. SQL Server cannot process this media family.

The backup was corrupted. The file was transferred using FTP in text mode rather than binary mode.
