Script for automated backups in the SQL Server with DD boost

How can I use the command line ddbmsqlsv.exe with xp_cmdshell in SQL script for backup all databases in instance?

I try:

DECLARE @name VARCHAR(50)

DECLARE @path VARCHAR(1000)

DECLARE @server VARCHAR(1000)

SELECT  convert(varchar,SERVERPROPERTY('MachineName'))

DECLARE db_cursor CURSOR FOR 

SELECT name

FROM master.dbo.sysdatabases

WHERE name NOT IN ('master','model','msdb','tempdb')  -- exclude these databases

OPEN db_cursor  

FETCH NEXT FROM db_cursor INTO @name  

WHILE @@FETCH_STATUS = 0  

BEGIN  

  set @path='C:\Scripts\ddboost.bat  '+@name

  --print @path

  execute xp_cmdshell @path

        FETCH NEXT FROM db_cursor INTO @name  

END  

CLOSE db_cursor  

DEALLOCATE db_cursor

---

In ddboost.bat I have:

ddbmsqlsv.exe -c SERVER  -l full -a NSR_DFA_SI=TRUE -a NSR_DFA_SI_USE_DD=TRUE -a NSR_DFA_SI_DD_HOST=dddomain.com -a NSR_DFA_SI_DD_USER=user  -a NSR_DFA_SI_DEVICE_PATH=/SERVER MSSQL:%1

But when a execute the SQL, this error occurs:

ddbmsqlsv.exe -c SERVER  -l full -a NSR_DFA_SI=TRUE -a NSR_DFA_SI_USE_DD=TRUE -a NSR_DFA_SI_DD_HOST=ddboost.com -a NSR_DFA_SI_DD_USER=user  -a NSR_DFA_SI_DEVICE_PATH=/SERVER

In command line (cmd) I execute command without problems. It's works!

What's wrong with the combination xp_cmdshell and ddbmsqlsv.exe?
