*If* NT Backup is implementing the (old) Reel-to-reel 'labeled tapes'
format it might, *IF* the other backup tool is ALSO using the (old)
Reel-to-reel 'labeled tapes' format. Too big IFs and a big also -- none
of which are likely. So it seems more likely that there is another flavor
of NT Backup floating around somewhere in your past... One that creates
compressed NT Backup sets. Or else the tapes are crupted somehow.

What's the precise error message it gives?

Ooh, I remember that. It was _very_ useful for spanning floppies.

ok.

>(6,7,8,9, Win1, Win2)?
Maybe. I remember having trouble with different versions of CPBackup
and having to keep a copy of the program used to make floppy sets with
each set because of version incompatibilities. Don't know whather that
applies to tapes though.
>Is there any chance it was still made using NT Backup?
Well, as you say later, NT backup recognises the tapes and their labels
and descriptions, they were probably written with that.
Is it possible that the tape drive has been changed or had hardware
compression disabled? (I can't remember if QIC drives supported
hardware compression.) i.e. could this be a _hardware_ compression
problem?

There's plenty of free Windows tar utilities. A "tar -tv //./tape0"
will soon tell you. There's a choice of graphical ones and command line
ones.
I installed one called Tar98 years ago, just found it and it still seems
to work (on XP), but I don't have a tape drive installed any more. (It
looks for a Windows device //./tape0, so if you have that, it should
work.) It comes with utilities called Tapedump, Tapefeatures, and
Tapeutility which might be useful.
>Is it likely that NT Backup could show such descriptions, if the

Very unlikely in my opinion. NTBackup usually says something along the
lines of "unrecognized, unformatted or blank tape" when it encounters a
tape format it doesn't recognise.
Can you boot a Linux live CD and do a "file /dev/st0"? That may give
you some clues.

Ok, some new information.
Today I restored NTBackup from WinNT 3.1 and WinNT 3.5 installations.
While WinNT 3.5 shows the same message as the WinNT4 version (I'm
german and thus use german NT, so I can only give MY translations in
english):
Dieser Satz ist komprimiert und kann weder angezeigt noch
wiederhergestellt werden.
This set is compressed and cannot be displayed or restored.
The NTBackup of NT 3.1 says (this was the SDK version which apparently
was in english):
Images backups connot be viewed or restored.
While this could well be a translation error in the German NT version,
in the line descibing the backup set NT3.5 and 4 say:
E: Satz 1 Band 1 norm 04.10.97 14:33:19 E:\Privat...
While the 3.1 version says:
E: Set 1 Tape 1 image 04.10.97 14:33:19 E:\Privat...
So what to think about this?
I never heard of NTBackup doing Image Backups, although the is a /SNAP
command line option, but what that does, I don't really know.
Maybe I should go on asking this in some Windows NT forum?
Because its more a WinNT problem than a SCSI problem!?

I was going to mention in my last reply, but forgot, that NTBackup isn't
written by Microsoft. They bought in a backup utility from someone
else, but I can't remember who. Programs like Backup Exec have changed
owners/hands so many times.
There were, round about that time, several competing backup utilities,
but Backup Exec and Novastor are the only ones I recall.
The point is, I'm starting to wonder, with NTBackup reporting that it
cannot restore image backups, whether you have a tape written by a
later, further developed, version of the program that was bought in and
labelled NT Backup, i.e. one that supports compression and image backup.
I did have a quick Google to se if I could find out which company
supplied NT Backup to M$ but couldn't spot it.
Perhaps get a trial copy of Backup Exec and see what it makes of your
tapes?

Me neither.

I think a crosspost to a Windows group would be a good idea, yes. It'd
be interesting to see how you get on.

Oh, that's an easy one:
NT 3.1, NT Backup shows in the About dialog "Backup Version 1.0
Revison 3.16 SCSI Tape 1.0 (c) 1993 Conner Software."
NT 3.5, NT Backup shows "Microsoft Windows NT Bandsicherung Version
4.0 Copyright (c), 1993-1994 Arcada Software Inc."
NT 4, NT Backup shows "Microsoft Windows NT Bandsicherung Version 4.0
Copyright (c), 1993-1996 Seagate Software Inc."

That'll be Backup Exec then. Nothing else it could be. See if you can
find a version on http://www.oldversion.com/, if not, it shouldn't be
too hard to track down a copy.

Conner was eventually acquired by Seagate (perhaps by Arcada in the
interim), so I'm not sure that they should be considered totally
foreign. Of course it has happened that even within one company a new
version of a program cannot use files created by an earlier version.

The strange thing is, I connot remember to have ever used anything
else then CPBackup (mainly floppies) and NTBackup.
Yet, there is some small chance, that I used some version of Backup
Exec I "copied" from work.
On www.oldversion.com I couldn't find ANY sort of backup software.
Maybe i'm blind...
I wasted all the day for searching for some backup/restore software,
that could read tapes written in compressed MTF (MS tape format)
format.
There are a lot of tools for reading (corrupted) BKF files, but only
from disk, which doesn't help me much.
I FOUND some backup programs, but they all didn't run on WinNT4.

If you can install cygwin you would have dd, which would let you copy
the tape to disk and then use the 'tools for reading (corrupted) BKF
files'.
