Hey there,

we're having an issue with ntbackup. The program runs fine if we start
the backup from the GUI. However, using the schedular or the commandline
gives an error the device or medium is not found (freely translated from
dutch 'Kan het aangewezen medium of back-upapparaat niet vinden. De
back-upbewerking wordt afgebroken.').

I think it has to do with the issue with had with the tape drive (a
compaq dat 20/40). This was probably a defect in the SCSI controller.
You could some commands (like selftest from HP tape tools, or eject from
removable storage) fine, however any command that would read or write to
the tape would cause the device to freeze up and dissapear from the
device manager as well. At first I thought it might be a driver issue,
so I downloaded the driver from compaq and installed that. Same issue,
so I replaced the SCSI card and then it functioned fine (I had also
removed the Compaq/HP driver so back to the microsoft driver).

Anyways, now the cli doesn't find the tape drive thus, whilst it works
fine from GUI. I think it might be looking for the old tape drive, or
perhaps on the old controller, but don't know where to remove it.

Anyone know how to fix this?

TIA

Hmm how wierd... You might give Peter Weston's mt for Windows tool a
try and see if it can see and operate your tape drive. It's a command
like tape control program that is handy to have around anyways, as it
does useful things like seek to a certain block, eject, rewind,
retension, etc. You can get it here: http://www.holistech.co.uk/sw/mt/mt.html
.. Whether it errors or works, that might give you a clue as to what
is going on. I'd also suggest (if you haven't already) making sure
that backup to file works from the command line with ntbackup. If
that works you can probably be safe assuming that there is nothing
wrong with ntbacukp running jobs from the command line. HTH

Still have to try the tool, but the ntbackup GUI works fine for tape
(the cli/schedular just doesn't). Also backup2file works w/o any problems.

Anyways thx for the re'
