I've tried to run this console command:

SqlCmd -E -S MyServer –Q “BACKUP DATABASE [MyDB] TO DISK=’D:BackupsMyDB.bak'”

But it did not work!

Please help )

Everyone, even non-registered users could send Bitcoin Tips to YOU if they are inspired by your answer!

Basically there are two steps:

Create a stored procedure in your master db. See msft link or if it's broken try here:

USE [master]
GO
/****** Object:  StoredProcedure [dbo].[sp_BackupDatabases]    Script Date: 5/25/2013 2:38:32 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

  1. Run this code from the console and make backups:

sqlcmd -S YOURSERVERNAME\SQLEXPRESS -E -Q "EXEC spBackupDatabases @backupLocation='C:\SQLBackup\', @backupType='F'" 1>c:\SQL_Backup\backup.log

To create a full database backup

  • Execute the BACKUP DATABASE statement to create the full database backup, specifying:

       o    The name of the database to back up.
    
    
       o    The backup device where the full database backup is written.
    
    
    The basic Transact-SQL syntax for a full database backup is:
     BACKUP DATABASE database
     TO backup_device [ ,...n ]
     [ WITH with_options [ ,...o ] ] ;
    

    enter image description here

         2. Optionally, specify one or more WITH options. A few basic WITH options are described here.    For information about all the WITH options, see BACKUP (Transact-SQL).
    
    
    
         o  Basic backup set WITH options:
    
    
        { COMPRESSION | NO_COMPRESSION }
    
    
        In SQL Server 2008 Enterprise and later only, specifies whether backup compression is performed                  on this backup, overriding the server-level default.
    
    
      Note:The server-level default is set by using the backup compression default option.
    
    
        DESCRIPTION = { 'text' | @text_variable }
    
    
        Specifies the free-form text that describes the backup set. The string can have a maximum of 255                 characters.
    
    
       NAME = { backup_set_name | @backup_set_name_var }
    
    
       Specifies the name of the backup set. Names can have a maximum of 128 characters. If NAME is not specified, it is blank.
    
    
      o Basic backup set WITH options:
    
    
       By default, BACKUP appends the backup to an existing media set, preserving existing backup sets.   To explicitly specify this, use the NOINIT option. For more information, see Appending to Existing Backup Sets.
    
    
        Alternatively, to format the backup media, use the FORMAT option:
    
    
        FORMAT [ , MEDIANAME= { media_name | @media_name_variable } ] [ , MEDIADESCRIPTION = { text |@text_variable } ]
    
    
      Use the FORMAT clause when you are using media for the first time or you want to overwrite all existing data. Optionally, assign the new media a media name and description.
    

Important : Use extreme caution when you are using the FORMAT clause of the BACKUP statement because this destroys any backups that were previously stored on the backup media.

            Example
          A. Backing up to a disk device

          The following example backs up the complete AdventureWorks2008R2 database to disk, by using   FORMAT to create a new media set.

          USE AdventureWorks2008R2;

          GO

         BACKUP DATABASE AdventureWorks2008R2

          TO DISK = 'Z:\SQLServerBackups\AdventureWorks2008R2.Bak'
           WITH FORMAT,

           MEDIANAME = 'Z_SQLServerBackups',

           NAME = 'Full Backup of AdventureWorks2008R2'

            GO

           B. Backing up to a tape device

           The following example backs up the complete AdventureWorks2008R2 database to tape, appending the backup to the previous backups.

           USE AdventureWorks2008R2;    

            GO

           BACKUP DATABASE AdventureWorks2008R2

           TO TAPE = '\\.\Tape0'

          WITH NOINIT,  

         NAME = 'Full Backup of AdventureWorks2008R2';

         GO

         C. Backing up to a logical tape device

         The following example creates a logical backup device for a tape drive. The example then backs up the complete AdventureWorks2008R2 database to that device.

       -- Create a logical backup device, 

       -- AdventureWorks2008R2_Bak_Tape, for tape device \\.\tape0.
          USE master;

             C. Backing up to a logical tape device

            The following example creates a logical backup device for a tape drive. The example then backs up              the complete AdventureWorks2008R2 database to that device.

          -- Create a logical backup device, 

          -- AdventureWorks2008R2_Bak_Tape, for tape device \\.\tape0.
              USE master;
