Hello,

Does anyone have a link to a windows FD binary that supports windows NT 4.0?

For one of my customers, I support a windows NT 4.0 (SP6?) machine. This
device is mission critical for my customer to operate a CNC milling
machine. I've taken what steps I can to isolate the machine from the
network. It has a dedicated path back to my rocky linux 9 server, for
filesharing purposes. Frequently modified files (CAD drawings, gcode
machine tool path files) are stored on the fileshare. Generally, the files
and configuration for this device don't change very much, so an old system
image has generally proven suitable for backup purposes.

However, this is changing for reasons unrelated to the machine itself
(explained below). Recently an application on the NT 4.0 machine suffered
corruption in one of its INI files. I was able to restore a suitable backup
from my system image, but I'd like to back up the drive on a more frequent
basis if possible. Some of the corrupted application files weren't found in
my system image, and while I got away with it this time I'd like better
protection.

I already use bacula to back up the fileserver. Is an NT 4.0 windows binary
out there somewhere? My googling only found 13.0.4 and 15.0.2 windows
binaries on bacula.org. I did find references to NT support in the bacula
5.x manual, so maybe a bacula 5.x windows fd binary could work?

I've seen discussion of issues backing up user workstations recently on the
list, and I suspect that even if I do have a suitable binary, I will face
similar issues with this NT host. The NT computer is turned on along with
the milling machine, when the main power switch is thrown. The system runs
on 386 era hardware, so is quite single thread limited. Even if I configure
backup jobs to run automatically once the machine starts or while it is
turned on, I am concerned that the FD could hog resources that the
controller needs to do its job of instructing the hardware on where to go.

It occurs to me that I could try to train the operator of this machine to
manually run a backup. Unfortunately, the operator is elderly, and has
somewhat diminished capacity. In this last year, backups have become much
more important because of this. I am concerned that if I rely on this
operator to run backups, the backups may not run.

Finally, even if you don't have any information on this, please, if you
think you're 'slipping' mentally, go to a doctor. My customer has
unknowningly been having micro-strokes for years, and only this year did he
finally have a big one. Turns out he really was 'slipping' as he's feared
since I met him in 2017. Now he's substantially worse off than before. The
doctor determined that he'd had 4 strokes because there were 4 different
areas in his brain with reduced activity. Only one of them had happened
recently. If he'd managed to prevent even this most recent stroke he'd be
so much better off.
