TITLE   :Command Line NTBackup Won't Backup Files Using UNC Naming
PRODUCT :Windows NT
PROD/VER:3.10
OPER/SYS:WINDOWS
KEYWORDS:

-----------------------------------------------------------------------
The information in this article applies to:
 
 - Microsoft Windows NT operating system version 3.1
 - Microsoft Windows NT Advanced Server version 3.1
-----------------------------------------------------------------------
 
Windows NT Backup (NTBACKUP.EXE) does not support uniform naming
convention (UNC) naming for paths. For example, when issuing the
command
 
   ntbackup backup \\server1\share\<dirname>
 
Windows NT Backup will not backup any files in the specified
directory, even though files exist in the directory (\<dirname>).
 
MORE INFORMATION
================
 
This might be an issue for someone (such as a network administrator)
who wants to make nightly backups using the AT command (which
schedules programs to run on a computer at a specified time and date).
 
For example, you may want to issue the following command
 
   AT 3:30am backup.bat
 
where the contents of the BACKUP.BAT file are the following:
 
   ntbackup backup \\server1\share\sys
 
When you are using UNC naming conventions, you can avoid mapping a
drive letter to a network resource; however, Windows NT Backup does
not support UNC naming. 

In the above example, then, the correct contents for the BACKUP.BAT is
the following:
 
   rem Disconnect the current network resource if it exists.
   net use o: /d
   rem Connect to the correct network resource for the backup.
   net use o: \\server1\share
   rem Run the backup to the network resource.
   ntbackup backup o:\sys
   rem Disconnect the current network resource.
   net use o: /d
