  Hi.

  I have MS SQLServer 2005

  I'm trying to backup database to named pipe.

  I use SQL statement

  BACKUP DATABASE [mydb] TO  DISK = N'\\.\pipe\mytest1' WITH NOFORMAT, NOINIT,  NAME = N'mydb-Full Database Backup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10

   

  Obviously when I tried to execute this command I received an error

  "Cannot open backup device '\\.\pipe\mytest1'"

  I think this is because the pipe was not created.

  I wrote command line application that creates pipe '\\.\pipe\mytest1'.

  I used CreateNamedPipe() Windows API function

  I executed this command line application and immediately after this executed BACKUP DATABASE SQL statement

  I received another error

  "Cannot open backup device '\\.\pipe\mytest1'. Operating system error 231(All pipe instances are busy.). "

   

  What is the problem?

  May be I opened pipe a wrong way?

  May be problem is in SQL statement?

  Is there another way to backup database into named pipe?

   

  Thanks for advance.

  Try it like this.  When connecting to the server, force a Named Pipe connection.  Afterwards, just do you're backup to the drive\path.

  Instead of <servername>

  try

  np:<servername>

  in the Connect To dialog box.
