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 that this is a problem in Windows NT version 4.0.
