Command Line NTBackup Won't Backup Files Using UNC Naming

   ntbackup backup \\server1\share\<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
