Q110481: Backup Doesn’t Back Up Entire Hard Disk or Create Log File

Article: Q110481
Product(s): Microsoft Windows NT
Version(s): 3.1
Operating System(s): 
Keyword(s): kbtool
Last Modified: 08-AUG-2001

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Advanced Server, version 3.1 
- Microsoft Windows NT Workstation version 3.1 
-------------------------------------------------------------------------------

SYMPTOMS
========

NTBACKUP.EXE does not back up the entire hard disk drive when issued from the
command line or from a batch file. Also, the following error may appear:

  You do not have permission to access portions of \xxx Please see the owner or
  administrator to get permission. Error reading alternate file data.

where "xxx" will be part of the subdirectory path name.

If you use the command line statement:

  NTBACKUP backup C:\<directory path> /B /L "C:\BACKUP.LOG"

NTBackup will back up the specified directory, but will not back up the local
registry as specified by the /B switch. If the specified directory is not the
root directory, the following error message will appear in the status box:

  You do not have permission to access portions of \xxx. Please see the owner
  or administrator to get permission. Error reading alternate file data.

NTBACKUP.EXE will also create an empty log file with a size of 2 bytes and write
it in the \\WINNT directory instead of the path specified by the /L switch.

CAUSE
=====

In Service Pack 2 for Windows NT, NTBACKUP.EXE was modified to recognize
Unicode. This caused a regression problem where it did not parse command line
parameters correctly.

RESOLUTION
==========

Service Pack 2 has been re-released with a correction for this problem.

If you applied the previous Service Pack 2 before 1/31/94, you need to update
Windows NT to the new version.

To determine if you have the new Service Pack 2 on a running system, at a command
prompt type "WINVER".

If WINVER shows that the release is:

  Build 528: CSD003  - you have the old Service Pack 2.

If WINVER shows that the release is:

  Build 528: Service Pack 2  - you have the new Service Pack 2.

STATUS
======

Microsoft has confirmed this to be a problem in Windows NT and Windows NT
Advanced Server version 3.1. This problem has been corrected in the latest U.S.
Service Pack for Windows NT and Windows NT Advanced Server version 3.1. For
