BUG: NTBackup can't backup individual files from a batch file or via a command prompt

ID: Q216789

The information in this article applies to:

Microsoft Windows NT Server version 4.0
Microsoft Windows NT Workstation version 4.0
Microsoft Windows 2000 Professional
Microsoft Windows 2000 Server
Microsoft Windows 2000 Advanced Server

SYMPTOMS

When you run NTBackup from the command line or from a batch file, and you specify a single file to be backed up, (for example: ntbackup backup c:\xfer\test.txt /D "Test One" /l "c:\backup.log"), you will consistently get the following error condition:

You do not have permission to access portions of specified path\filename.

CAUSE

By design, NTBackup can only back up directories when using a batch file or through a command prompt.

RESOLUTION

To work around this problem, specify the directory in which the file you want to back up resides, for example:


   ntbackup backup c:\xfer /d "Test Two" /l "c:\backup.log"

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0.
