The MS-DOS 5.0 BACKUP command cannot perform a backup to a Novell NetWare drive. If you attempt to do so, the following error message may be displayed:

Cannot backup to a drive which is ASSIGNed JOINed or SUBSTed
Microsoft has confirmed this to be a problem with MS-DOS 5.0. We are researching this problem and will post new information as it becomes available.

You can backup from a NetWare drive to another NetWare drive, or from a NetWare drive to a local drive. A workaround may be to use the NetWare NBACKUP command.

The BACKUP command from MS-DOS versions 3.x or 4.x usually works correctly with a NetWare drive.
